Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
IS 11169 (Part 1) 15C4C (IS 11169 (Part 1):2022) and BS 970 (Part 1) 055M15 (BS 970 (Part 1):1991) are both steel grades.
Both fall under the Carbon Steel category.
IS 11169 (Part 1) 15C4C is typically used for cold heading and cold extrusion of parts not heat treated after cold forming; the standard covers bars, wire rods and wires of 2 to 100 mm (clause 1.1, annex a), while BS 970 (Part 1) 055M15 is commonly used for as-rolled, or as-rolled and softened, steel (section two).
IS 11169 (Part 1) 15C4C is defined under Bureau of Indian Standards (IS), originating from India, while BS 970 (Part 1) 055M15 is defined under British Standards (BS), originating from United Kingdom.
As per chemical composition, IS 11169 (Part 1) 15C4C vs BS 970 (Part 1) 055M15 is a 61.1% match.
As per mechanical properties, the match is 0%.
Combined, this makes them a minimal match overall at 35%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
