Related Material — 69.9% match
based on chemical composition and mechanical property overlap.
BS 970 (Part 1) 655M13 (BS 970 (Part 1):1991) and EN 10084 16NiCr4 (EN 10084:2008) are both steel grades.
Both fall under the Alloy Steel category.
BS 970 (Part 1) 655M13 is typically used for case hardened gears, heavily loaded shafts, while EN 10084 16NiCr4 is commonly used for case hardened machine parts: carburized or carbonitrided, then hardened (clause 3.1).
BS 970 (Part 1) 655M13 is defined under British Standards (BS), originating from United Kingdom, while EN 10084 16NiCr4 is defined under European Standard (EN), originating from Europe.
As per chemical composition, BS 970 (Part 1) 655M13 vs EN 10084 16NiCr4 is a 70.6% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a related material overall at 69.9%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
