Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
EN 10089 55Si7 (EN 10089:2002) and IS 3195 50Cr4V2 (IS 3195:1992) are both steel grades.
Both fall under the Spring Steel category.
EN 10089 55Si7 is typically used for leaf springs, coil springs, torsion bars, while IS 3195 50Cr4V2 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 10089 55Si7 is defined under European Standard (EN), originating from Europe, while IS 3195 50Cr4V2 is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, EN 10089 55Si7 vs IS 3195 50Cr4V2 is a 65.2% 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.
