Related Material — 69.9% match
based on chemical composition and mechanical property overlap.
NF A35-552 XC38 (NF A35-552:1986) and BS 970 (Part 3) 070M20 (BS 970 (Part 3):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 3) 070M20 is commonly 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).
NF A35-552 XC38 is defined under Association Francaise de Normalisation (NF), originating from France, while BS 970 (Part 3) 070M20 is defined under British Standards (BS), originating from United Kingdom.
As per chemical composition, NF A35-552 XC38 vs BS 970 (Part 3) 070M20 is a 88.3% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a related material overall at 69.9%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
