Strong Match — 94.7% match
based on chemical composition and mechanical property overlap.
BS 970 (Part 3) 045M10 (BS 970 (Part 3):1991) and JIS G4051 S10C (JIS G4051:2009) are both steel grades.
Both fall under the Carbon Steel category.
BS 970 (Part 3) 045M10 is typically 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), while JIS G4051 S10C is commonly used for case hardened pins, bushes, small shafts.
BS 970 (Part 3) 045M10 is defined under British Standards (BS), originating from United Kingdom, while JIS G4051 S10C is defined under Japanese Industrial Standards (JIS), originating from Japan.
As per chemical composition, BS 970 (Part 3) 045M10 vs JIS G4051 S10C is a 94.7% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a strong match overall at 94.7%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
