Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
IS 3195 55Si7 (IS 3195:1992) and EN 10089 55Cr3 (EN 10089:2002) are both steel grades.
Both fall under the Spring Steel category.
IS 3195 55Si7 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 10089 55Cr3 is commonly used for automotive leaf springs, heavy coil springs.
IS 3195 55Si7 is defined under Bureau of Indian Standards (IS), originating from India, while EN 10089 55Cr3 is defined under European Standard (EN), originating from Europe.
As per chemical composition, IS 3195 55Si7 vs EN 10089 55Cr3 is a 76.8% 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.
