Strong Match — 93.2% match
based on chemical composition and mechanical property overlap.
EN 10084 C10R (EN 10084:2008) and IS 4432 10C4 (IS 4432:1988) 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 IS 4432 10C4 is commonly used for forgings and fabrication of case-hardened machine or automobile parts.
EN 10084 C10R is defined under European Standard (EN), originating from Europe, while IS 4432 10C4 is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, EN 10084 C10R vs IS 4432 10C4 is a 89.8% match.
As per mechanical properties, the match is 100%.
Combined, this makes them a strong match overall at 93.2%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
