Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
EN 10083-3 51CrV4 (EN 10083-3:2006) and IS 3195 52Cr4Mo2V (IS 3195:1992) are both steel grades.
Both fall under the Spring Steel category.
EN 10083-3 51CrV4 is typically used for valve springs, clutch springs, high duty coil springs, while IS 3195 52Cr4Mo2V is commonly used for volute and helical springs for railway rolling stock; flats and rounds, springs worked hot and heat-treated (clause 1.1, foreword).
EN 10083-3 51CrV4 is defined under European Standard (EN), originating from Europe, while IS 3195 52Cr4Mo2V is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, EN 10083-3 51CrV4 vs IS 3195 52Cr4Mo2V is a 80.8% 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.
