JIS G4801 SUP9A vs IS 3195 52Cr4Mo2V

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

JIS G4801 SUP9A (JIS G 4801:2005) and IS 3195 52Cr4Mo2V (IS 3195:1992) are both steel grades. Both fall under the Spring Steel category. JIS G4801 SUP9A is typically used for heavy duty leaf springs, torsion bars, 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). JIS G4801 SUP9A is defined under Japanese Industrial Standards (JIS), originating from Japan, while IS 3195 52Cr4Mo2V is defined under Bureau of Indian Standards (IS), originating from India.

As per chemical composition, JIS G4801 SUP9A vs IS 3195 52Cr4Mo2V is a 65.8% 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%.
