Strong Match — 85.8% match
based on chemical composition and mechanical property overlap.
EN 10084 17CrS3 (EN 10084:2008) and IS 4432 15Cr3-S (IS 4432:1988) are both steel grades.
Both fall under the Alloy Steel category.
EN 10084 17CrS3 is typically used for case hardened machine parts: carburized or carbonitrided, then hardened (clause 3.1), while IS 4432 15Cr3-S is commonly used for forgings and fabrication of case-hardened machine or automobile parts.
EN 10084 17CrS3 is defined under European Standard (EN), originating from Europe, while IS 4432 15Cr3-S is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, EN 10084 17CrS3 vs IS 4432 15Cr3-S is a 78.8% match.
As per mechanical properties, the match is 100%.
Combined, this makes them a strong match overall at 85.8%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
