Strong Match — 99.7% match
based on chemical composition and mechanical property overlap.
EN 10083-1 C40E (EN 10083-1:1996) and EN 10083-2 C40E (EN 10083-2:2006) are both steel grades.
Both fall under the Carbon Steel category.
EN 10083-1 C40E is typically used for quenched and tempered machine parts; also used normalized (clause 1.1, table 10), while EN 10083-2 C40E is commonly used for quenched and tempered, flame or induction hardened machine parts; can also be used normalized (clause 1).
EN 10083-1 C40E is defined under European Standard (EN), originating from Europe, while EN 10083-2 C40E is defined under European Standard (EN), originating from Europe.
As per chemical composition, EN 10083-1 C40E vs EN 10083-2 C40E is a 99.6% match.
As per mechanical properties, the match is 100%.
Combined, this makes them a strong match overall at 99.7%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
