Close Alternative — 80.4% match
based on chemical composition and mechanical property overlap.
EN 10084 14NiCrMo13-4 (EN 10084:2008) and BS 970 EN36C (BS 970:1955) are both steel grades.
Both fall under the Alloy Steel category.
EN 10084 14NiCrMo13-4 is typically used for case hardened machine parts: carburized or carbonitrided, then hardened (clause 3.1), while BS 970 EN36C is commonly used for used for gears, camshafts, pinions, heavy-duty shafts, aerospace transmission parts, and worm drives..
EN 10084 14NiCrMo13-4 is defined under European Standard (EN), originating from Europe, while BS 970 EN36C is defined under British Standards (BS), originating from United Kingdom.
As per chemical composition, EN 10084 14NiCrMo13-4 vs BS 970 EN36C is a 80.4% 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 80.4%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
