Close Alternative — 82% match
based on chemical composition and mechanical property overlap.
IS 3195 60Cr4V2 (IS 3195:1992) and JIS G4801 SUP9A (JIS G 4801:2005) are both steel grades.
Both fall under the Spring Steel category.
IS 3195 60Cr4V2 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 JIS G4801 SUP9A is commonly used for heavy duty leaf springs, torsion bars.
IS 3195 60Cr4V2 is defined under Bureau of Indian Standards (IS), originating from India, while JIS G4801 SUP9A is defined under Japanese Industrial Standards (JIS), originating from Japan.
As per chemical composition, IS 3195 60Cr4V2 vs JIS G4801 SUP9A is a 82% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a close alternative overall at 82%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
