Related Material — 69.9% match
based on chemical composition and mechanical property overlap.
EN 10084 C10R (EN 10084:2008) and BS 970 (Part 1) 060A78 (BS 970 (Part 1):1991) are both steel grades.
Both fall under the Carbon Steel category.
EN 10084 C10R is typically used for case hardened machine parts: carburized or carbonitrided, then hardened (clause 3.1), while BS 970 (Part 1) 060A78 is commonly used for as-rolled, or as-rolled and softened, steel (section two).
EN 10084 C10R 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 10084 C10R vs BS 970 (Part 1) 060A78 is a 79.6% 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.
