Minimal Match — 51.9% match
based on chemical composition and mechanical property overlap.
IS 1570 (Part 4) 55Cr3 (IS 1570 (Part 4):1988) and UNI 11234 100Cr6 (UNI 11234:2007) are both steel grades.
Both fall under the Alloy Steel category.
IS 1570 (Part 4) 55Cr3 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 1570 (Part 4) 55Cr3 vs UNI 11234 100Cr6 is a 73.1% match.
As per mechanical properties, the match is 9.5%.
Combined, this makes them a minimal match overall at 51.9%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
