Strong Match — 85.9% match
based on chemical composition and mechanical property overlap.
BS 970 EN7 (BS 970:1955) and BS 970 (Part 1) 214A15 (BS 970 (Part 1):1983) are both steel grades.
Both fall under the Free Machining Steel category.
BS 970 EN7 is typically used for bright bars for machining. a semi-free cutting modification of en 6 for certain restricted applications., while BS 970 (Part 1) 214A15 is commonly used for case hardening steel for mechanical and allied engineering purposes (table 11 mechanical properties)..
BS 970 EN7 is defined under British Standards (BS), originating from United Kingdom, while BS 970 (Part 1) 214A15 is defined under British Standards (BS), originating from United Kingdom.
As per chemical composition, BS 970 EN7 vs BS 970 (Part 1) 214A15 is a 85.9% 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 85.9%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
