Strong Match — 85.2% match
based on chemical composition and mechanical property overlap.
IS 4432 15Cr3-S (IS 4432:1988) and EN 10084 17Cr3 (EN 10084:2008) are both steel grades.
Both fall under the Alloy Steel category.
IS 4432 15Cr3-S is typically used for forgings and fabrication of case-hardened machine or automobile parts, while EN 10084 17Cr3 is commonly used for case hardened machine parts: carburized or carbonitrided, then hardened (clause 3.1).
IS 4432 15Cr3-S is defined under Bureau of Indian Standards (IS), originating from India, while EN 10084 17Cr3 is defined under European Standard (EN), originating from Europe.
As per chemical composition, IS 4432 15Cr3-S vs EN 10084 17Cr3 is a 77.8% match.
As per mechanical properties, the match is 100%.
Combined, this makes them a strong match overall at 85.2%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
