Related Material — 69.9% match
based on chemical composition and mechanical property overlap.
UNI 7845 C45 (UNI 7845:1978) and BS 970 (Part 3) 045M10 (BS 970 (Part 3):1991) are both steel grades.
Both fall under the Carbon Steel category.
UNI 7845 C45 is typically used for shafts,axles,gears,studs,bolts,spindles,rollers,general engineering components, 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).
UNI 7845 C45 is defined under Ente Nazionale Italiano di Unificazione (UNI), originating from Italy, while BS 970 (Part 3) 045M10 is defined under British Standards (BS), originating from United Kingdom.
As per chemical composition, UNI 7845 C45 vs BS 970 (Part 3) 045M10 is a 85.3% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a related material overall at 69.9%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
