IS 11169 (Part 1) 20C8GC vs BS 970 (Part 3) 045M10
Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
IS 11169 (Part 1) 20C8GC (IS 11169 (Part 1):2022) and BS 970 (Part 3) 045M10 (BS 970 (Part 3):1991) are both steel grades.
Both fall under the Carbon Steel category.
IS 11169 (Part 1) 20C8GC 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 3) 045M10 is commonly used for bright cold finished bars (cold drawn, turned or precision ground) for general engineering purposes, in straight lengths; case hardening steel, carbon and carbon manganese (table 14).
IS 11169 (Part 1) 20C8GC is defined under Bureau of Indian Standards (IS), originating from India, while BS 970 (Part 3) 045M10 is defined under British Standards (BS), originating from United Kingdom.
As per chemical composition, IS 11169 (Part 1) 20C8GC vs BS 970 (Part 3) 045M10 is a 56.1% 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%.
Frequently Compared With IS 11169 (Part 1) 20C8GC:
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
