Minimal Match — 50.1% match
based on chemical composition and mechanical property overlap.
IS 4367 15Cr3 (IS 4367:1991) and UNI 11234 100Cr6 (UNI 11234:2007) 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 UNI 11234 100Cr6 is commonly used for ball bearings,roller bearings,needle bearings,dies,punches,gauges,wear resistant components.
IS 4367 15Cr3 is defined under Bureau of Indian Standards (IS), originating from India, while UNI 11234 100Cr6 is defined under Ente Nazionale Italiano di Unificazione (UNI), originating from Italy.
As per chemical composition, IS 4367 15Cr3 vs UNI 11234 100Cr6 is a 75.2% match.
As per mechanical properties, the match is 0%.
Combined, this makes them a minimal match overall at 50.1%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
