Close Alternative — 77.5% match
based on chemical composition and mechanical property overlap.
IS 11169 (Part 1) 15Ni5Cr5 (IS 11169 (Part 1):2022) and BS 970 EN36B (BS 970:1955) are both steel grades.
Both fall under the Alloy Steel category.
IS 11169 (Part 1) 15Ni5Cr5 is typically used for cold heading and cold extrusion of parts that are case hardened; the standard covers bars, wire rods and wires of 2 to 100 mm (clause 1.1, annex b), while BS 970 EN36B is commonly used for case hardened gears and heavily loaded components.
IS 11169 (Part 1) 15Ni5Cr5 is defined under Bureau of Indian Standards (IS), originating from India, while BS 970 EN36B is defined under British Standards (BS), originating from United Kingdom.
As per chemical composition, IS 11169 (Part 1) 15Ni5Cr5 vs BS 970 EN36B is a 77.5% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a close alternative overall at 77.5%.
Frequently Compared With IS 11169 (Part 1) 15Ni5Cr5:
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
