Close Alternative — 83.6% match
based on chemical composition and mechanical property overlap.
BS 970 EN36B (BS 970:1955) and IS 11169 (Part 1) 13Ni14Cr3 (IS 11169 (Part 1):2022) are both steel grades.
Both fall under the Alloy Steel category.
BS 970 EN36B is typically used for case hardened gears and heavily loaded components, while IS 11169 (Part 1) 13Ni14Cr3 is commonly 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).
BS 970 EN36B is defined under British Standards (BS), originating from United Kingdom, while IS 11169 (Part 1) 13Ni14Cr3 is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, BS 970 EN36B vs IS 11169 (Part 1) 13Ni14Cr3 is a 83.6% 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 83.6%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
