Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
GB/T 1222 55CrMnA (GB/T 1222-2016) and IS 3195 52Cr4Mo2V (IS 3195:1992) are both steel grades.
Both fall under the Spring Steel category.
GB/T 1222 55CrMnA is typically used for automotive leaf springs, coil springs, while IS 3195 52Cr4Mo2V 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).
GB/T 1222 55CrMnA is defined under Guobiao Standards (GB/T), originating from China, while IS 3195 52Cr4Mo2V is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, GB/T 1222 55CrMnA vs IS 3195 52Cr4Mo2V is a 67.7% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
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.
