Strong Match — 98.8% match
based on chemical composition and mechanical property overlap.
EN 10084 C10R (EN 10084:2008) and EN 10084 C10E (EN 10084:2008) are both steel grades.
Both fall under the Carbon Steel category.
EN 10084 C10R is typically used for case hardened machine parts: carburized or carbonitrided, then hardened (clause 3.1), while EN 10084 C10E is commonly used for case hardened machine parts: carburized or carbonitrided, then hardened (clause 3.1).
EN 10084 C10R is defined under European Standard (EN), originating from Europe, while EN 10084 C10E is defined under European Standard (EN), originating from Europe.
As per chemical composition, EN 10084 C10R vs EN 10084 C10E 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.
