Strong Match — 89.8% match
based on chemical composition and mechanical property overlap.
BS 970 (Part 3) 655M13 (BS 970 (Part 3):1991) and BS 970 EN36B (BS 970:1955) are both steel grades.
Both fall under the Alloy Steel category.
BS 970 (Part 3) 655M13 is typically used for bright cold finished bars (cold drawn, turned or precision ground) for general engineering purposes, in straight lengths; alloy case hardening steel (table 15), while BS 970 EN36B is commonly used for case hardened gears and heavily loaded components.
BS 970 (Part 3) 655M13 is defined under British Standards (BS), originating from United Kingdom, while BS 970 EN36B is defined under British Standards (BS), originating from United Kingdom.
As per chemical composition, BS 970 (Part 3) 655M13 vs BS 970 EN36B is a 89.8% 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 89.8%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
