Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
JIS G4801 SUP9 (JIS G 4801:2005) and IS 3195 113C6 (IS 3195:1992) are both steel grades.
Both fall under the Spring Steel category.
JIS G4801 SUP9 is typically used for automotive leaf springs, suspension springs, while IS 3195 113C6 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).
JIS G4801 SUP9 is defined under Japanese Industrial Standards (JIS), originating from Japan, while IS 3195 113C6 is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, JIS G4801 SUP9 vs IS 3195 113C6 is a 79.6% 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.
