Steel Castings Sectional Committee, MTD 17

FOREWORDThis Indian Standard (Fifth Revision) was adopted by the Bureau of Indian Standards, after the drawlfinalizedby the Steel Castings Sectional Committee had been approved by the Metallurgical Engineering Division Council.This standard was first published in 1956 and was revised in 1962, 1974, 1982 and 1989. While reviewing thestandard in light of the experience gained during these years the committee has decided that the standard maybe further revised. In this revision various clauses have been aligned with the recent standards on steel castings.Amendments No. 1 and 2 have also been incorporated in this revision.In the preparation of this standard, assistance has been derived from IS0 3755 : 1991 Cast carbon steels forgeneral engineering purposes.For the purpose of deciding whether a particular requirement of this standard is complied with, the final value,observed or calculated, expressing the result of a test or analysis, shall be rounded off in accordance withIS 2 : 1960 Rules for rounding off numerical values (revised). The number of significant places retained inthe rounded off value should be the same as that of the specified value in this standard.

ENGINEERING PURPOSES - SPECIFICATION(Fifth Revision)

1 SCOPEThis standard covers the requirements for carbon steelcastings for general engineering purposes.2 REFERENCESThe Indian Standards listed in Annex A are necessaryadjuncts to this standard.3 TERMINOLOGYFor the purpose of this standard, the followingdefinitions shall apply.3.1 Cast (Melt)The product of any of the following:

a)Wc)

One furnace heat,One crucible heat, orA number of furnace or crucible heats of simi-lar composition mixed in a ladle or tapped inseparate ladles and poured simultaneously formaking a casting.

3.2 BatchA group of castings of one grade of material, cast fromthe same melt and heat-treated together under identicalconditions.4 GRADES4.1 This standard covers a total of eight grades ofcarbon steel castings for general engineering purposes.4.2 Included in 8 grades are 4 grades with chemicalcomposition restricted to ensure ease of welding atthe purchasers end and these grades carry thesuffix W.5 SUPPLY OF MATERIALGeneral requirements relating to supply of steelcastings shall be as laid down in IS 8800.6 MANUFACTURESteel for the castings shall be made by electric arc or

7 PARTICULARS TO BE SPECLFIED WHILEORDERINGFor the benefit of the purchaser, particulars to bespecified while ordering for steel castings to thisspecification are given in Annex B.8 CHEMICAL COMPOSITION8.1 The ladle analysis of steel when carried out eitherby the method specified in IS 228 and its relevant partsor any other established instrumental/chemicalmethods shall be as given in Table 1. In case of disputethe procedure given in IS 228 shall be the refereemethod. However, where the method is not given inIS 228, the referee method shall be as agreed tobetween the purchaser and the manufacturer.8.2 The manufacturer shall carry out analysis from asample of each melt and, if so specified by thepurchaser at the time of enquiry and order, shall supplya test certificate of chemical analysis of the sample ofsteel for each melt.8.3 Product AnalysisIf specified at the time of enquiry and order, productanalysis may be carried out from a test piece or from acasting representing each melt. Drillings for analysisshall be taken from not less than 6 mm beneath thecast surface, and in such a manner as not to impairthe usefulness of any casting selected. The permissiblevariation in product analysis from the limits specifiedin Table 1 shall be as given in IS 660 1.8.4 Residual Elements8.4.1 Elements not specified in Table 1 shall notordinarily be added to the steel and all reasonabicprecautions shall be taken to prevent contaminationfrom scrap, etc, to keep them as low as practicable.8.4.2 Analysis and reporting of the analysis in testcertificate for the residual elements shall be done onlywhen so specified by the purchaser in enquiry and order.However, the manutacturer shall ensure that the residualelements are within the limits, when such limits arespecified by the purchaser in enquiry and order.

On other dimensions, toler-ances specified in IS 4897 shall apply.10 FREEDOM FROM DEFECTS10.1 All castings shall be free from defects that willadversely a&ct machining or utility of castings.10.2 When necessary to remove risers or gates byflame or arc or a combination thereof, or by any otherprocess involving intense heat, care shall be takento make the cut at a sufDcient distance from the bodyof the casting so as to prevent any defect beingintroduced into the casting due to local heating. Anysuch operation is to be done before final heattreatment.10.3 In the event of any casting proving defectivefrom foundry causes in the course of preparation,machining or erection, such a casting may be rejectednotwithstanding any previous certification of satisfac-tory testing and/or inspection.11 FETTLING AND DRESSINGAll castings shall be properly fettled and dressed, andall surfaces shall be thoroughly cleaned.12 HEAT TREATMENT12.1 The castings shall be heat treated in a properlyconstructed furnace, having adequate means oftemperature control, which shall permit the whole of

the castings to be uniformly heated to the necessarytemperature. All castings shall be suitably heat treatedso as to attain the specified mechanical properties.12.2 Unless otherwise specified in enquiry and orderor agreed to between the purchaser and the manufac-turer, all castings shall either be fully annealed ornormalized or normalized and tempered.12.3 Test pieces shall be heat treated along with thecastings they represent.13 MECHANICAL TESTS13.1 The mechanical properties specified are thosewhich are to be obtained from test bars cast eitherseparately fromor attached to the castings to whichthey refer and heat treated as given in 12. The testvalues so exhibited, therefore, represent the quality ofsteel from which the castings have been poured; theydo not necessarily represent the properties of thecastings themselves.13.2 The tensile test shall be carried out inaccordance with IS 1608. The relevant mechanicalproperties shall be asgiven in Table 2.13.3 If specified in enquiry and order, impact testshall be carried out in accordance with IS 1757 andthe values obtained shall conform to the requirementsgiven in Table 2.13.4 Bend TestIf so specified at the time of enquiry and order thebend test shall be carried out in accordance withIS 1599. l&t pieces shall be capable of being bentcold without fracture to an angle given in Table 2 rounda mandrel having a diameter of 50 mm.
