Strong Match — 91.9% match
based on chemical composition and mechanical property overlap.
BS 970 EN16 (BS 970:1955) and BS 970 (Part 3) 605M36 (BS 970 (Part 3):1991) are both steel grades.
Both fall under the Alloy Steel category.
BS 970 EN16 is typically used for high tensile bolts, studs, general engineering, while BS 970 (Part 3) 605M36 is commonly used for bright cold finished bars (cold drawn, turned or precision ground) for general engineering purposes, in straight lengths; alloy direct hardening steel (table 16).
BS 970 EN16 is defined under British Standards (BS), originating from United Kingdom, while BS 970 (Part 3) 605M36 is defined under British Standards (BS), originating from United Kingdom.
As per chemical composition, BS 970 EN16 vs BS 970 (Part 3) 605M36 is a 91.9% 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 91.9%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
