Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
EN 10083-2 C50E (EN 10083-2:2006) and BS 970 (Part 1) 045A10 (BS 970 (Part 1):1991) are both steel grades.
Both fall under the Carbon Steel category.
EN 10083-2 C50E is typically used for quenched and tempered, flame or induction hardened machine parts; can also be used normalized (clause 1), while BS 970 (Part 1) 045A10 is commonly used for case hardening steel (section four).
EN 10083-2 C50E is defined under European Standard (EN), originating from Europe, while BS 970 (Part 1) 045A10 is defined under British Standards (BS), originating from United Kingdom.
As per chemical composition, EN 10083-2 C50E vs BS 970 (Part 1) 045A10 is a 59.4% match.
As per mechanical properties, the match is 0%.
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.
