Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
BS 4659 BH11 (BS 4659:1989) and EN ISO 683-17 100Cr6 (EN ISO 683-17:2014) are both steel grades.
Both fall under the Tool & Die Steels category.
BS 4659 BH11 is typically used for die casting dies, extrusion tooling, while EN ISO 683-17 100Cr6 is commonly used for rolling element bearings, precision components, cold work tooling.
BS 4659 BH11 is defined under British Standards (BS), originating from United Kingdom, while EN ISO 683-17 100Cr6 is defined under European Standard (EN), originating from Europe.
As per chemical composition, BS 4659 BH11 vs EN ISO 683-17 100Cr6 is a 63.1% match.
As per mechanical properties, the match is 0%.
Combined, this makes them a minimal match overall at 35%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
