Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
IS 3195 65Si7 (IS 3195:1992) and EN 10083-1 51CrV4 (EN 10083-1:1996) are both steel grades.
Both fall under the Spring Steel category.
IS 3195 65Si7 is typically used for volute and helical springs for railway rolling stock; flats and rounds, springs worked hot and heat-treated (clause 1.1, foreword), while EN 10083-1 51CrV4 is commonly used for quenched and tempered machine parts (clause 1.1).
IS 3195 65Si7 is defined under Bureau of Indian Standards (IS), originating from India, while EN 10083-1 51CrV4 is defined under European Standard (EN), originating from Europe.
As per chemical composition, IS 3195 65Si7 vs EN 10083-1 51CrV4 is a 65.9% 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.
