Minimal Match — 48.4% match
based on chemical composition and mechanical property overlap.
EN 10083-1 37Cr4 (EN 10083-1:1991) and UNI 11234 100Cr6 (UNI 11234:2007) are both steel grades.
Both fall under the Alloy Steel category.
EN 10083-1 37Cr4 is typically used for quenched and tempered machine parts; non alloy steels also normalized (clause 1), while UNI 11234 100Cr6 is commonly used for ball bearings,roller bearings,needle bearings,dies,punches,gauges,wear resistant components.
EN 10083-1 37Cr4 is defined under European Standard (EN), originating from Europe, while UNI 11234 100Cr6 is defined under Ente Nazionale Italiano di Unificazione (UNI), originating from Italy.
As per chemical composition, EN 10083-1 37Cr4 vs UNI 11234 100Cr6 is a 72.7% match.
As per mechanical properties, the match is 0%.
Combined, this makes them a minimal match overall at 48.4%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
