Minimal Match — 48.5% match
based on chemical composition and mechanical property overlap.
EN 10083-1 38Cr2 (EN 10083-1:1991) and NF A35-565 100C6 are both steel grades.
Both fall under the Alloy Steel category.
EN 10083-1 38Cr2 is typically used for quenched and tempered machine parts; non alloy steels also normalized (clause 1), while NF A35-565 100C6 is commonly used for ball bearings, roller bearings, bearing races, rollers, precision tools, wear resistant parts.
EN 10083-1 38Cr2 is defined under European Standard (EN), originating from Europe, while NF A35-565 100C6 is defined under Association Francaise de Normalisation (NF), originating from France.
As per chemical composition, EN 10083-1 38Cr2 vs NF A35-565 100C6 is a 72.8% match.
As per mechanical properties, the match is 0%.
Combined, this makes them a minimal match overall at 48.5%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
