Close Alternative — 76.3% match
based on chemical composition and mechanical property overlap.
EN 10084 15NiCr13 (EN 10084:2008) and BS 970 (Part 1) 655M13 (BS 970 (Part 1):1991) are both steel grades.
Both fall under the Alloy Steel category.
EN 10084 15NiCr13 is typically used for heavily loaded gears, cams, camshafts, while BS 970 (Part 1) 655M13 is commonly used for case hardened gears, heavily loaded shafts.
EN 10084 15NiCr13 is defined under European Standard (EN), originating from Europe, while BS 970 (Part 1) 655M13 is defined under British Standards (BS), originating from United Kingdom.
As per chemical composition, EN 10084 15NiCr13 vs BS 970 (Part 1) 655M13 is a 76.3% 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 76.3%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
