Strong Match — 91.6% match
based on chemical composition and mechanical property overlap.
BS 970 (Part 1) 216M44 (BS 970 (Part 1):1983) and BS 970 EN8M (BS 970:1955) are both steel grades.
Both fall under the Free Machining Steel category.
BS 970 (Part 1) 216M44 is typically used for through hardening steel for mechanical and allied engineering purposes; supplied in the hardened and tempered conditions of table 6., while BS 970 EN8M is commonly used for high volume turned parts, automotive components.
BS 970 (Part 1) 216M44 is defined under British Standards (BS), originating from United Kingdom, while BS 970 EN8M is defined under British Standards (BS), originating from United Kingdom.
As per chemical composition, BS 970 (Part 1) 216M44 vs BS 970 EN8M is a 91.6% 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 91.6%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
