IS 3195 98C6 vs GB/T 1222 55CrMnA

Minimal Match — 35% match based on chemical composition and mechanical property overlap.

IS 3195 98C6 (IS 3195:1992) and GB/T 1222 55CrMnA (GB/T 1222-2016) are both steel grades. Both fall under the Spring Steel category. IS 3195 98C6 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 GB/T 1222 55CrMnA is commonly used for automotive leaf springs, coil springs. IS 3195 98C6 is defined under Bureau of Indian Standards (IS), originating from India, while GB/T 1222 55CrMnA is defined under Guobiao Standards (GB/T), originating from China.

As per chemical composition, IS 3195 98C6 vs GB/T 1222 55CrMnA is a 77.4% 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%.
