1. The company

Metrode was founded in 1963 as a privately owned company. In the subsequent years it has grown to become the UK's leadingmanufacturer and supplier of alloyed welding consumables. It is particularly strong in those industries which require the highestintegrity from their welding consumables, such as power generation, chemical and petrochemical, offshore oil and gas, LNG andnuclear. In the last decade the export market has been vigorously developed and Metrode has markets globally. It also has anextensive overseas network of distributors and agents as well as a distribution network covering the whole of the UK. November2006, Metrode joined the Lincoln Electric Company as a business unit within Lincoln Electric Europe.

2. Scope

This handbook is designed to provide information on the company, its products and services and guidance on the correct choice ofwelding consumables.This 2016 edition of the Technical Handbook (revision 13) contains over 100 data sheets covering about 350 arc welding consumables.About half of these are flux covered manual metal arc electrodes. These are complemented by a wide range of solid wires, tubularflux cored and metal cored wires for the other popular arc welding processes. The range has applications for all industriallysignificant steels and alloy systems except for titanium, magnesium, aluminium and rarer metals. Particular emphasis is currentlybeing devoted to developing a strategy with consumables for the power generation industries, offshore oil and gas industries, hightemperature materials in the chemical and petrochemical industries and a diverse range of nickel based alloys. Data sheets forsome fringe products are not included in this handbook, but are available on request.

Technical support is available to help with any aspect of consumable choice, applications or procedural guidance.Field based staff can advise on procedural aspects and factors needed to achieve optimum performance.Facilities are available at Metrode for demonstration, training and evaluation for all the major welding processes which utiliseMetrode consumables.

10. Specifications and certification

Metrode consumables are manufactured to conform with the current issues of BS EN, BS EN ISO or AWS-ASME standards whereapplicable. When incompatible variations exist between different specifications for equivalent types, these are indicated on thedata sheet. Where a product does not strictly conform to a standard the specification is shown in brackets for guidance only.Every batch is certified at least with chemical analysis to BS EN 10204: 3.1, with a few exceptions amongst some hardfacing/maintenance types certified to BS EN 10204: 2.2.Special requirements for batch testing or analysis variants are frequently satisfied with prior agreement.

11. Health and safety

Welding produces fumes and gases which can be dangerous to your health. Arc rays can injure eyes and burn skin. Electricshock can kill.It is important to take suitable precautions when welding, and to follow safe working practices. These should be based uponinformation available from the Welding Manufacturers' Association leaflet and Metrode's Health and Safety booklet which maybe obtained from Metrode or our distributors.

GENERAL EXPLANATORY NOTESEach data sheet is headed with a unique number for easy reference. The same number also appears at the bottom right handcorner of each page of the data sheet.Data sheet revision status is given at the foot of the page.

The Metrode designation in bold type should be used when ordering. It is printed on each electrode, stamped on many TIG wiresand identifies all package labels.Each data sheet is sub-divided under self-explanatory headings, some of which are briefly outlined below.

Materials to be weldedExamples are given of typical base materials for which the consumable may be used. It should not be assumed that this is aguarantee of suitability, and should be used with caution.Reference is made to proprietary alloy names for many base materials and we acknowledge the use of registered trade names fromHaynes International Inc, Special Metals, VDM and RA Materials Ltd.

ApplicationsInformation is given for general guidance and in good faith, but the user should ascertain that the product is suitable for the specific

and intended purpose.

Welding guidelinesBrief guidelines on preheat, post weld heat treatment (PWHT) and any particular procedural requirements are given for each alloy.The user is responsible for establishing a satisfactory welding procedure.

Additional informationUseful background information, procedural notes, precautions and published references are given where appropriate. Technicalprofiles are also available for a number of products.

Specifications, approvalsSee specification notes above. For some products which do not strictly conform to a particular specification, the nearestspecification is shown in brackets for guidance. If a required approval is not shown, contact Metrode

CompositionComposition limits are declared for almost every product in addition to typical values.Where it is possible to meet BS EN, BS EN ISO and AWS-ASME compositions with one product, this is often reflected in tighter datasheet limits than the individual specifications. Whilst in rare cases a batch may not satisfy all these constraints, BS EN ISO or AWS-ASME are normally the default specifications unless agreed otherwise. See also specification notes on previous introductory page.Note that flux covered MMA electrodes and tubular cored wires are defined by all-weld deposit analysis, solid wires by productanalysis, and fluxes by deposit analysis from appropriate combination with relevant solid wires.

All-weld mechanical propertiesMinimum and typical tensile and impact properties are given where applicable to satisfy national specifications or materialrequirements. Caution is generally advised in translating these all-weld (longitudinal) values to joint (transverse) test values.

DATA SHEETS: INTRODUCTION AND EXPLANATORY NOTES

Operating parametersCurrent ranges are based on satisfactory fusion and arc stability. Optimum conditions are influenced by variables such as weldingposition, base material thickness, and heat input considerations, etc. Most electrodes operate smoothly on DC+ (positive electrode)and for those suitable for AC a minimum OCV (open circuit voltage) is given.Welding positions for electrodes are shown pictographically. Where vertical and overhead are indicated this usually applies to3.2mm and smaller sizes, with 4mm practicable with skilled operators and joints with sufficient room for manipulation. Wherevertical down is indicated, this applies to 2.5mm or 3.2 with skilled operators.

Packaging dataFor electrodes, the length, weight per carton (3 tins) and approximate number of pieces per carton are given, but may be subject tochange without notice. For TIG, MIG, SAW and FCW, tube, spool and coil weights are also provided. Contact Metrode for latestinformation if required.Note that Metrode electrodes are supplied in hermetically sealed tins with ring-pull opening. The integrity of this packaging isregularly assessed according to the ASME SFA5.5 procedure. Tins provide a convenient and economic alternative to smaller unitsof vacuum-packed electrodes in 'site packs' which can be supplied to order.Redrying (rebaking or conditioning), handling and storage recommendations are given. Redrying should ensure that the unpackedelectrodes reach the recommended temperature-time conditions.The majority of electrodes and TIG wires are marked individually with both the designation or classification number and batchnumber.

Fume dataTo assist health and safety hazard assessment, welding fume composition is given for each product. Fume itself comprises oxides,silicates or other complex compounds of the elements listed.An occupational exposure limit or standard (OES) is calculated in milligrams per cubic metre breathing zone concentration. Thiscontrol value is 5mg/m3 maximum, or much lower for many alloyed consumables. For example, a significant proportion of thechromium in fume generated by stainless covered electrodes and flux cored wire is present in hexavalent form with a limit of0.05mg/m3, which reduces total fume OES to around 1mg/m3. In fume generated by solid stainless MIG wires, practically allchromium is trivalent and the total fume OES is higher.TIG and submerged arc processes generate too little fume for assessment on this basis.In the UK, COSHH guidance relevant to welding is found in HMSO publications, EH40, EH54 and EH55.

Section A : Low Alloy Steels

LOW ALLOY STEELS INCLUDING THE CrMo CREEP RESISTING CONSUMABLES

METRODE PRODUCTS LTDHANWORTH LANE, CHERTSEYSURREY, KT16 9LL, UKTel: +44(0)1932 566721 / Fax: +44(0)1932 565168Email: [email protected]: www.metrode.com

This section includes consumables suitable for welding general engineering and structural steels, from medium tensile grain-refinedCMn and semi-cryogenic steels (approximately –75°C) to specialised heat and creep-resistant CrMo types reaching the threshold ofstainlessness at 12%Cr.Flux coverings of all electrodes are of all-positional basic low-hydrogen type and employ binders giving high resistance to moistureabsorption. All flux cored wires are rutile all-positional types also with low hydrogen potential. With increasing weld and base metalstrength and hardenability (or carbon equivalent), a hydrogen potential below 5ml/100g weld metal is often an essential proceduralparameter, coupled with preheat where necessary to moderate HAZ hardening or raise safety margins in thicker sections:

For guidance, preheat up to 50°C for CE < 0.40, 100°C for < 0.55, 150°C for < 0.70, 200°C for < 0.80, 250°C for 0.90 or above. However,note that some cases require restricted preheat-interpass and also heat input control to maintain optimum strength and toughness.High joint restraint may require higher preheats.A full discussion of this subject is given in the following publication: N. Bailey, F.R. Coe et al: ‘Welding steels without hydrogencracking’, Abington Publishing, Cambridge, 1993.The necessity for Post Weld Heat Treatment (PWHT) varies with base and weld metal type. PWHT is normally essential to temperthe HAZ below 248HV/22HRC required by NACE for H2S service, for which electrodes giving mandatory < 1%Ni with strength andtoughness are available. Most nickel-bearing electrodes also give excellent as-welded properties at low temperatures. PWHT isessential for creep-resisting Cr-Mo types, although the leaner low carbon variants are sometimes stress-relieved in service when usedfor repairs under local preheat.

APPLICATIONSNominal 0.5% Mo alloying results in improvedelevated temperature performance over that ofCMn steels. Used for the fabrication of vessels andassociated pipework demanding creep rupturestrength and ductility at temperatures up to about

450°C.The Mo content also enhances resistance tohydrogen attack in chemical process plantoperation.

Favourable mechanical properties of both as-welded and stress-relieved weld metal are also

useful in welding structural and general engineering

steels for ambient or sub-zero temperature service.

In this respect these consumables are related to

the higher strength manganese-molybdenum

alloyed steel consumables.

MICROSTRUCTUREIn the stress-relieved condition the microstructureconsists of acicular ferrite with some temperedbainite.

PWHTPWHT to temper the weldment varies accordingto the code; the extremes range from 550°C up to

720°C but the most common range is 630-670°C.For material up to 20mm thick some codes allowthe PWHT to be omitted.

WELDING GUIDELINESPreheat and interpass temperatures are normallyin the range 100-250°C depending upon thicknessbeing welded and restraint.

RELATED ALLOY GROUPSFor high strength structural welding applicationsthe MnMo alloys (A-50) are related.

APPLICATIONSFor elevated temperature service up to 600°C, withcorrosion resistance in superheated steam, hothydrogen gas and high sulphur crude oils.Used primarily for boiler superheaters, heat exchangers,piping and pressure vessels in oil refineries.This weld metal has also been used successfully forsubsequent nitriding, for example in the repair of 3Cr-

1Mo-V and 2Cr-Mo-1A1 (BS En40C, En41) steels used formoulds for injection-moulding of plastics.

MICROSTRUCTUREIn the PWHT condition the microstructure consistsof tempered bainite.

PWHT

PWHT to temper the weldment would normally bein the range 705-760°C (eg. BS2633 & PD5500 710-750°C, ASME B31.3 705-760°C). Minimum holdingtime recommended is two hours. For castings theminimum suggested PWHT temperature is lower,with temperatures as low as 670°C being specified.

WELDING GUIDELINESOwing to the as-deposited hardness (up to 400HV)and the relatively poor fracture resistance of the5CrMo bainitic microstructure, a preheat andminimum interpass temperature of 200°C should

be applied to ensure freedom from hydrogeninduced cold cracking. Properly controlled andhandled electrodes will provide weld metal withhydrogen 150°C) to PWHT ispermissible, followed by NDE. If PWHT will beapplied after complete cool out and NDE, thepreheat temperature should be maintained forsome time after welding, according to thickness,to promote hydrogen dispersal. The latterprecaution is less significant for the TIG and solidwire MAG processes.

APPLICATIONSThese consumables are designed to weld equivalent‘type 91’ 9CrMo steels modified with small additionsof niobium, vanadium and nitrogen to give improvedlong term creep properties.These consumables are specifically intended for highintegrity structural service at elevated temperatureso the minor alloy additions responsible for its creepstrength are kept above the minimum considerednecessary to ensure satisfactory performance. In

this case, weldments will be weakest in the softened(intercritical) HAZ region of parent material, asindicated by so-called ‘type IV’ failure in transverseweld creep tests.Modified 9CrMo steels are now widely used forcomponents such as headers, main steam piping,valves and turbine casings, in fossil fuelled powergenerating plants. They may also find future use inoil refineries and coal liquefaction and gasificationplants.

PWHTMinimum preheat temperature 150°C withmaximum interpass temperature of 300°C; inpractice a preheat-interpass range of 200–300°Cis normal.To ensure full martensite transformation, weldsshall be cooled to ~100°C prior to PWHT.ASME base material codes and AWS consumableclassifications allow PWHT down to 730°C, whilstBS EN consumable classifications specify 750°C.

Optimum properties are obtained with a temperingparameter (P) of around 21 or above, whereP = °C+273 (log t + 20) x 10–3. Maximum PWHTtemperature varies, AWS consumable specificationsare 760°C, BS EN 770°C; BS 1503 allows up to 790°Cfor base material forgings.When compared with directly matching weldmetal, the addition of some nickel and reductionof niobium provides a useful improvement intoughness after conveniently short PWHT at750–760°C. PWHT above 765°C is not generally

recommended for Ni-containing consumables,because some re-hardening could occur due tothe proximity of Ac

1. Some authorities specify weld

metal Ni + Mn < 1.5% to keep Ac 1 high enough to

allow higher PWHT temperature if required.
