Related Material — 69.9% match
based on chemical composition and mechanical property overlap.
BS 970 EN2 (BS 970:1955) and BS 970 (Part 3) 070M55 (BS 970 (Part 3):1991) are both steel grades.
Both fall under the Carbon Steel category.
BS 970 EN2 is typically used for lightly stressed components, case hardened parts, while BS 970 (Part 3) 070M55 is commonly used for used for springs, blades, wear plates, hand tools, shafts, and cutting components..
BS 970 EN2 is defined under British Standards (BS), originating from United Kingdom, while BS 970 (Part 3) 070M55 is defined under British Standards (BS), originating from United Kingdom.
As per chemical composition, BS 970 EN2 vs BS 970 (Part 3) 070M55 is a 81% 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.
