Strong Match — 93.2% match
based on chemical composition and mechanical property overlap.
IS 4432 10C4 (IS 4432:1988) and EN 10084 C10R (EN 10084:2008) are both steel grades.
Both fall under the Carbon Steel category.
IS 4432 10C4 is typically used for forgings and fabrication of case-hardened machine or automobile parts, while EN 10084 C10R is commonly used for case hardened machine parts: carburized or carbonitrided, then hardened (clause 3.1).
IS 4432 10C4 is defined under Bureau of Indian Standards (IS), originating from India, while EN 10084 C10R is defined under European Standard (EN), originating from Europe.
As per chemical composition, IS 4432 10C4 vs EN 10084 C10R 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.
