Minimal Match — 32.8% match
based on chemical composition and mechanical property overlap.
BS 970 EN41A (BS 970:1955) and IS 11169 (Part 1) 10Ni5Cr4 (IS 11169 (Part 1):2022) are both steel grades.
Both fall under the Alloy Steel category.
BS 970 EN41A is typically used for bars and billets for forging; forgings and drop-forgings; bars for machining; bright bars. suitable for 45/55 (r), 50/60 (s), 55/65 (t) tons/sq in; selection of en 41a or 41b governed by tensile range required., while IS 11169 (Part 1) 10Ni5Cr4 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 EN41A is defined under British Standards (BS), originating from United Kingdom, while IS 11169 (Part 1) 10Ni5Cr4 is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, BS 970 EN41A vs IS 11169 (Part 1) 10Ni5Cr4 is a 49.1% match.
As per mechanical properties, the match is 0%.
Combined, this makes them a minimal match overall at 32.8%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
