Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
IS 11169 (Part 1) 45C8 (IS 11169 (Part 1):2022) and BS 970 (Part 1) 045M10 (BS 970 (Part 1):1991) are both steel grades.
Both fall under the Carbon Steel category.
IS 11169 (Part 1) 45C8 is typically used for cold heading and cold extrusion of parts that are quenched and tempered; the standard covers bars, wire rods and wires of 2 to 100 mm (clause 1.1, annex c), while BS 970 (Part 1) 045M10 is commonly used for case hardening steel (section four).
IS 11169 (Part 1) 45C8 is defined under Bureau of Indian Standards (IS), originating from India, while BS 970 (Part 1) 045M10 is defined under British Standards (BS), originating from United Kingdom.
As per chemical composition, IS 11169 (Part 1) 45C8 vs BS 970 (Part 1) 045M10 is a 65% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
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.
