Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
EN 10083-3 34CrNiMo6 (EN 10083-3:2006) and IS 1570 (Part 4) 103Cr6 (IS 1570 (Part 4):1988) are both steel grades.
Both fall under the Alloy Steel category.
EN 10083-3 34CrNiMo6 is defined under European Standard (EN), originating from Europe, while IS 1570 (Part 4) 103Cr6 is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, EN 10083-3 34CrNiMo6 vs IS 1570 (Part 4) 103Cr6 is a 59.9% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a minimal match overall at 35%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
