Minimal Match — 53% match
based on chemical composition and mechanical property overlap.
DIN 17200 28Mn6 (DIN 17200:1986) and BS 970 (Part 1) 055M15 (BS 970 (Part 1):1991) are both steel grades.
Both fall under the Carbon Steel category.
DIN 17200 28Mn6 is typically used for unalloyed manganese carbon steel for quenching and tempering; shafts and machine components requiring good hardenability, moderate strength, while BS 970 (Part 1) 055M15 is commonly used for as-rolled, or as-rolled and softened, steel (section two).
DIN 17200 28Mn6 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 17200 28Mn6 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.
