Minimal Match — 53.6% match
based on chemical composition and mechanical property overlap.
NF A35-552 XC38 (NF A35-552:1986) and BS 970 (Part 1) 055M15 (BS 970 (Part 1):1991) are both steel grades.
Both fall under the Carbon Steel category.
NF A35-552 XC38 is typically used for shafts, pins, connecting rods, machined parts, forgings, agricultural equipment parts, while BS 970 (Part 1) 055M15 is commonly used for as-rolled, or as-rolled and softened, steel (section two).
NF A35-552 XC38 is defined under Association Francaise de Normalisation (NF), originating from France, while BS 970 (Part 1) 055M15 is defined under British Standards (BS), originating from United Kingdom.
As per chemical composition, NF A35-552 XC38 vs BS 970 (Part 1) 055M15 is a 80.4% match.
As per mechanical properties, the match is 0%.
Combined, this makes them a minimal match overall at 53.6%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
