Strong Match — 98.8% match
based on chemical composition and mechanical property overlap.
EN 10083-1 2C30 (EN 10083-1:1991) and EN 10083-1 C30R (EN 10083-1:1996) are both steel grades.
Both fall under the Carbon Steel category.
EN 10083-1 2C30 is typically used for quenched and tempered machine parts; non alloy steels also normalized (clause 1), while EN 10083-1 C30R is commonly used for quenched and tempered machine parts; also used normalized (clause 1.1, table 10).
EN 10083-1 2C30 is defined under European Standard (EN), originating from Europe, while EN 10083-1 C30R is defined under European Standard (EN), originating from Europe.
As per chemical composition, EN 10083-1 2C30 vs EN 10083-1 C30R is a 98.2% match.
As per mechanical properties, the match is 100%.
Combined, this makes them a strong match overall at 98.8%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
