Close Alternative — 82.6% match
based on chemical composition and mechanical property overlap.
EN 10084 C16R (EN 10084:2008) and BS 970 (Part 3) 045A10 (BS 970 (Part 3):1991) are both steel grades.
Both fall under the Carbon Steel category.
EN 10084 C16R is typically used for case hardened machine parts: carburized or carbonitrided, then hardened (clause 3.1), while BS 970 (Part 3) 045A10 is commonly used for bright cold finished bars (cold drawn, turned or precision ground) for general engineering purposes, in straight lengths; case hardening steel, carbon and carbon manganese (table 14).
EN 10084 C16R is defined under European Standard (EN), originating from Europe, while BS 970 (Part 3) 045A10 is defined under British Standards (BS), originating from United Kingdom.
As per chemical composition, EN 10084 C16R vs BS 970 (Part 3) 045A10 is a 82.6% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a close alternative overall at 82.6%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
