Close Alternative — 82.7% match
based on chemical composition and mechanical property overlap.
BS 970 EN14A/1 (BS 970:1955) and BS 970 (Part 3) 045M10 (BS 970 (Part 3):1991) are both steel grades.
Both fall under the Carbon Steel category.
BS 970 EN14A/1 is typically used for bars and billets for forging; forgings and drop-forgings; bars for machining. purchaser to state hot rolled or normalised., 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).
BS 970 EN14A/1 is defined under British Standards (BS), originating from United Kingdom, while BS 970 (Part 3) 045M10 is defined under British Standards (BS), originating from United Kingdom.
As per chemical composition, BS 970 EN14A/1 vs BS 970 (Part 3) 045M10 is a 82.7% 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 82.7%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
