Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
BS 970 EN36B (BS 970:1955) and NF A35-565 100C6 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 NF A35-565 100C6 is commonly used for ball bearings, roller bearings, bearing races, rollers, precision tools, wear resistant parts.
BS 970 EN36B is defined under British Standards (BS), originating from United Kingdom, while NF A35-565 100C6 is defined under Association Francaise de Normalisation (NF), originating from France.
As per chemical composition, BS 970 EN36B vs NF A35-565 100C6 is a 67.1% 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.
