Minimal Match — 48.7% match
based on chemical composition and mechanical property overlap.
BS 970 EN14A (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 EN14A is typically used for bars and billets for forging; forgings and drop-forgings; bars for machining; bright bars. suitable hardened and tempered for 40/50 (q) and 45/55 (r) tons/sq in according to ruling section; purchaser to state normalised, cold drawn or hardened and tempered q or r. when required as plate, sheet or strip order to bs 1449., 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 EN14A 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 EN14A vs IS 11169 (Part 1) 10Ni5Cr4 is a 60.5% match.
As per mechanical properties, the match is 25%.
Combined, this makes them a minimal match overall at 48.7%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
