Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
EN 10083-1 34Cr4 (EN 10083-1:1991) and IS 4367 10Cr9Mo10 (IS 4367:1991) are both steel grades.
Both fall under the Alloy Steel category.
EN 10083-1 34Cr4 is defined under European Standard (EN), originating from Europe, while IS 4367 10Cr9Mo10 is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, EN 10083-1 34Cr4 vs IS 4367 10Cr9Mo10 is a 61.4% match.
As per mechanical properties, the match is 0%.
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.
