Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
EN 10083-1 3C22 (EN 10083-1:1991) and BS 970 (Part 1) 060A78 (BS 970 (Part 1):1991) are both steel grades.
Both fall under the Carbon Steel category.
EN 10083-1 3C22 is typically used for quenched and tempered machine parts; non alloy steels also normalized (clause 1), while BS 970 (Part 1) 060A78 is commonly used for as-rolled, or as-rolled and softened, steel (section two).
EN 10083-1 3C22 is defined under European Standard (EN), originating from Europe, while BS 970 (Part 1) 060A78 is defined under British Standards (BS), originating from United Kingdom.
As per chemical composition, EN 10083-1 3C22 vs BS 970 (Part 1) 060A78 is a 62.7% 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.
