IS 11169 (Part 1):2022 41Cr2Ni2Mo2 Steel: Specifications & Listings
IS 11169 (Part 1):2022 41Cr2Ni2Mo2: Cold heading quality alloy steel 41Cr2Ni2Mo2 to IS 11169 (Part 1):2022 for quenching and tempering after cold heading or cold extrusion, supplied as wire rod, bars or wire of 2 to 100 mm. Maximum tensile strength annealed, cold drawn and annealed is 640 MPa. It can be ordered with hardenability requirements (H, HH or HL).
Cold heading and cold extrusion of parts that are quenched and tempered; the standard covers bars, wire rods and wires of 2 to 100 mm (clause 1.1, Annex C)
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.

Other composition limitsfrom the table notes and clauses
Values
Maximum unless a range is given (ladle analysis)
Silicon
Lower silicon contents may be agreed when ordering, with due regard to the effect on properties such as hardenability
Ordered with hardenability
Small deviations from these limits are allowed (not for sulphur and phosphorus): up to 0.01 percent for carbon and the Table 1 values for other elements
Deoxidation
Aluminium killed (clause 6.2)
Elements not listed are not added intentionally without the purchaser's agreement, except those used to finish the heat.
