Minimal Match — 51.5% match
based on chemical composition and mechanical property overlap.
IS 3195 113C6 (IS 3195:1992) and IS 3431 60Si7 (IS 3431:1982) are both steel grades.
Both fall under the Spring Steel category.
IS 3195 113C6 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 IS 3431 60Si7 is commonly used for heavy duty leaf springs,suspension springs,automotive springs,railway springs,high stress spring components.
IS 3195 113C6 is defined under Bureau of Indian Standards (IS), originating from India, while IS 3431 60Si7 is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, IS 3195 113C6 vs IS 3431 60Si7 is a 77.2% match.
As per mechanical properties, the match is 0%.
Combined, this makes them a minimal match overall at 51.5%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
