Close Alternative — 79.8% match
based on chemical composition and mechanical property overlap.
EN 10084 C16E (EN 10084:2008) and BS 970 (Part 1) 045M10 (BS 970 (Part 1):1991) are both steel grades.
Both fall under the Carbon Steel category.
EN 10084 C16E is typically used for case hardened machine parts: carburized or carbonitrided, then hardened (clause 3.1), while BS 970 (Part 1) 045M10 is commonly used for case hardening steel (section four).
EN 10084 C16E is defined under European Standard (EN), originating from Europe, while BS 970 (Part 1) 045M10 is defined under British Standards (BS), originating from United Kingdom.
As per chemical composition, EN 10084 C16E vs BS 970 (Part 1) 045M10 is a 79.8% 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 79.8%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
