Strong Match — 88.6% match
based on chemical composition and mechanical property overlap.
BS 970 EN2D (BS 970:1955) and BS 970 (Part 1) 045M10 (BS 970 (Part 1):1983) are both steel grades.
Both fall under the Carbon Steel category.
BS 970 EN2D is typically used for bars and billets for forging; forgings and drop-forgings; bars for machining, while BS 970 (Part 1) 045M10 is commonly used for case hardening steel for mechanical and allied engineering purposes (table 11 mechanical properties)..
BS 970 EN2D is defined under British Standards (BS), originating from United Kingdom, while BS 970 (Part 1) 045M10 is defined under British Standards (BS), originating from United Kingdom.
As per chemical composition, BS 970 EN2D vs BS 970 (Part 1) 045M10 is a 88.6% 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 88.6%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
