Close Alternative — 84.9% match
based on chemical composition and mechanical property overlap.
JIS G4051 S22C (JIS G4051:2009) and BS 970 (Part 3) 045A10 (BS 970 (Part 3):1991) are both steel grades.
Both fall under the Carbon Steel category.
JIS G4051 S22C is typically used for lightly stressed components, welded structures, while BS 970 (Part 3) 045A10 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).
JIS G4051 S22C is defined under Japanese Industrial Standards (JIS), originating from Japan, while BS 970 (Part 3) 045A10 is defined under British Standards (BS), originating from United Kingdom.
As per chemical composition, JIS G4051 S22C vs BS 970 (Part 3) 045A10 is a 87.5% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a close alternative overall at 84.9%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
