Corrosion

Metal surfaces in relative motion forced into contact with or without lubricant. Degradation by the

formation of micro-welds between the contacting surfaces.

Wear by relative movement of mineral particles of suitable hardness, shape and texture to remove

material from the metal surface.

Wear by relative movement under pressure of mineral particles of suitable hardness, shape and

texture to remove material from the metal surface, leaving superficial deformation.

As above but in a high-temperature environment, leading generally to softening of the metal or its

constituents.

Repeated high-speed impacts between mineral particles and a material surface. Local destruction

by tearing out of metallic grains.

Tearing out of grains from the metal surface by the formation and implosion of bubbles in a liquid in

rapid motion.

Impact between two materials, one of which provokes deformation or rupture of the surface of the

other. This phenomenon is controlled by the toughness or ductility of the two materials.

Cyclic deformation not exceeding the elastic limit of the material. Degradation over time by

localised stress concentrations.

Cyclic exposure to high temperatures leading to permanent deformation by alternate expansion

and contraction. Alteration of the structure and properties of the material.

Creation of a poorly adhering oxide layer that reforms constantly. Degradation by loss of material

thickness.

Degradation of the material by chemical reaction with its environment. Complex phenomenon

involving numerous parameters.

Repair by resurfacing to the original or specified dimensions.

Application of a corrosion-resistant protective cladding.

Layer of weld metal providing a good metallurgical transition between the base metal and the

coating. For welded joints between similar or dissimilar materials.

Ability of the material to resist impact, heat, friction and abrasion simultaneously for edge retention

of cutting tools.

Ability of a material to increase its surface hardness under the effect of impact or high pressure.

In general, this increases wear resistance.

Suitability for machining by removal of metal shavings, e.g. turning, milling or drilling.

Hardfacing - Cladding - Thermal Arc Spraying

Hardfacing by arc welding is a surfacing operation to extend the service life of industrial components, pre-emptivelyon new components, or as part of a maintenance programme.

The result of significant savings in machine down time and production costs has meant that this process has beenadopted across many industries.

For each industrial application and wear phenomena, there is a Welding Alloys cored welding wire to provide wearresistance. Due to the unrivalled flexibility and ease of application, cored wires are used in many situations inworkshops, on site, for new parts or for repair. An alloy may be deposited by various welding methods;

Open arc welding (O)

Gas shielded welding MIG/MAG (G)

Submerged arc welding (S)

Thermal spraying (as shown by the symbol)

Welding Alloys Quality Control teams are an integral part of the production process at all our production sites,to ensure our continued commitment to delivering high quality, standard-setting welding consumables.

Product Name Composition [%] - Co balance Hardness - 3 layers

Highly resistant to high temperature wear and metal-to-metal abrasion Particular ease of application due to its low cracking tendency Maintains a good level of hardness at high temperatures

Applications: straightening guides, vertical mill rolls and foot rolls in continuous casting

Equivalent alloy to STELLOY 6 with lower carbon Easier machining and reduced cracking tendency Recomended for buffering on large parts or for thick deposits

Combines all the outstanding properties of the cobalt base alloys, including abrasion and erosion resistance

Deposit of intermediate hardness with good machinability Wide field of applications: hot shearing tools, petrochemical and industrial valves, valves and valve s eats of marine engines,

pump sleeves and shafts

Equivalent alloy to STELLOY 6 with higher carbon Allows the required hardness to be obtained on low alloy steels from the first layer

Applications: small valves and valve gates, extrusion dies

Good resistance to abrasion by minerals on account of its high hardness

Particularly suited to the production of cutting tools Applications: wood and paper industries, extrusion screws for filled plastic

Highest hardness of the cobalt base alloy range, offering excellent resistance to abrasion and corrosion Self polishing, promotes scratch free sliding of abrasive materials Applications: rubber kneaders


Shielding Gas Recommendation

STELLOY (Cobalt base)

-The recommended shielding gas is 100% Argon (I1)

- Specific TIG versions available in diameter 1.2 mm and 1.6 mm.
