Close Alternative — 82.1% match
based on chemical composition and mechanical property overlap.
BS 970 EN36B (BS 970:1955) and EN 10084 15NiCr13 (EN 10084:2008) are both steel grades.
Both fall under the Alloy Steel category.
BS 970 EN36B is typically used for case hardened gears and heavily loaded components, while EN 10084 15NiCr13 is commonly used for heavily loaded gears, cams, camshafts.
BS 970 EN36B is defined under British Standards (BS), originating from United Kingdom, while EN 10084 15NiCr13 is defined under European Standard (EN), originating from Europe.
As per chemical composition, BS 970 EN36B vs EN 10084 15NiCr13 is a 82.1% 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 82.1%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
