Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
EN 10083-2 C60 (EN 10083-2:2006) and BS 970 (Part 1) 040A04 (BS 970 (Part 1):1991) are both steel grades.
Both fall under the Carbon Steel category.
EN 10083-2 C60 is typically used for used in springs, knives, wear plates, high-strength wires, and hand tools., while BS 970 (Part 1) 040A04 is commonly used for as-rolled, or as-rolled and softened, steel (section two).
EN 10083-2 C60 is defined under European Standard (EN), originating from Europe, while BS 970 (Part 1) 040A04 is defined under British Standards (BS), originating from United Kingdom.
As per chemical composition, EN 10083-2 C60 vs BS 970 (Part 1) 040A04 is a 60.9% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a minimal match overall at 35%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
