Strong Match — 92.5% match
based on chemical composition and mechanical property overlap.
SAE J404 E52100 (SAE J404:2009) and UNI 11234 100Cr6 (UNI 11234:2007) are both steel grades.
Both fall under the Alloy Steel category.
SAE J404 E52100 is typically used for chemistry-only alloy steel grade; see the composition notes for product scope, while UNI 11234 100Cr6 is commonly used for ball bearings,roller bearings,needle bearings,dies,punches,gauges,wear resistant components.
SAE J404 E52100 is defined under SAE International, originating from United States, while UNI 11234 100Cr6 is defined under Ente Nazionale Italiano di Unificazione (UNI), originating from Italy.
As per chemical composition, SAE J404 E52100 vs UNI 11234 100Cr6 is a 92.5% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a strong match overall at 92.5%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
