Strong Match — 97.3% match
based on chemical composition and mechanical property overlap.
BS 970 (Part 3) 150M36 (BS 970 (Part 3):1991) and BS 970 EN15 (BS 970:1955) are both steel grades.
Both fall under the Carbon Steel category.
BS 970 (Part 3) 150M36 is typically used for bright cold finished bars (cold drawn, turned or precision ground) for general engineering purposes, in straight lengths; carbon and carbon manganese steel (table 13), while BS 970 EN15 is commonly used for heavy duty shafts, couplings, general engineering.
BS 970 (Part 3) 150M36 is defined under British Standards (BS), originating from United Kingdom, while BS 970 EN15 is defined under British Standards (BS), originating from United Kingdom.
As per chemical composition, BS 970 (Part 3) 150M36 vs BS 970 EN15 is a 97.3% 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 97.3%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
