Minimal Match — 53% match
based on chemical composition and mechanical property overlap.
DIN 17204 36Mn5 (DIN 17204:1990-11) and BS 970 (Part 1) 055M15 (BS 970 (Part 1):1991) are both steel grades.
Both fall under the Carbon Steel category.
DIN 17204 36Mn5 is typically used for unalloyed manganese carbon steel for quenching and tempering, higher manganese content than 28mn6; shafts and machine components requiring higher hardenability and strength, while BS 970 (Part 1) 055M15 is commonly used for as-rolled, or as-rolled and softened, steel (section two).
DIN 17204 36Mn5 is defined under Deutsches Institut fur Normung (DIN), originating from Germany, while BS 970 (Part 1) 055M15 is defined under British Standards (BS), originating from United Kingdom.
As per chemical composition, DIN 17204 36Mn5 vs BS 970 (Part 1) 055M15 is a 79.6% match.
As per mechanical properties, the match is 0%.
Combined, this makes them a minimal match overall at 53%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
