Minimal Match — 48.5% match
based on chemical composition and mechanical property overlap.
DIN 17210 15Cr3 (DIN 17210:1986) and UNI 11234 100Cr6 (UNI 11234:2007) are both steel grades.
Both fall under the Alloy Steel category.
DIN 17210 15Cr3 is typically used for low-alloy chromium case-hardening (carburizing) steel; gears, shafts, pins, and machine components requiring a hard wear-resistant carburized surface with a tough core, while UNI 11234 100Cr6 is commonly used for ball bearings,roller bearings,needle bearings,dies,punches,gauges,wear resistant components.
DIN 17210 15Cr3 is defined under Deutsches Institut fur Normung (DIN), originating from Germany, while UNI 11234 100Cr6 is defined under Ente Nazionale Italiano di Unificazione (UNI), originating from Italy.
As per chemical composition, DIN 17210 15Cr3 vs UNI 11234 100Cr6 is a 72.8% match.
As per mechanical properties, the match is 0%.
Combined, this makes them a minimal match overall at 48.5%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
