Close Alternative — 84.5% match
based on chemical composition and mechanical property overlap.
IS 4367 15Cr3 (IS 4367:1991) and SAE J404 5115 (SAE J404:2009) are both steel grades.
Both fall under the Alloy Steel category.
IS 4367 15Cr3 is typically used for low-alloy chromium case-hardening steel; used for gears, shafts, and transmission components requiring higher core strength and wear resistance than plain carbon case-hardening grades, while SAE J404 5115 is commonly used for case hardened gears, cams, shafts.
IS 4367 15Cr3 is defined under Bureau of Indian Standards (IS), originating from India, while SAE J404 5115 is defined under SAE International, originating from United States.
As per chemical composition, IS 4367 15Cr3 vs SAE J404 5115 is a 84.5% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a close alternative overall at 84.5%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
