BS 970 EN48A vs IS 3195 52Cr4Mo2V

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

BS 970 EN48A (BS 970:1955) and IS 3195 52Cr4Mo2V (IS 3195:1992) are both steel grades. Both fall under the Spring Steel category. BS 970 EN48A is typically used for bars for oil hardening and tempering. laminated spring plates to this specification shall conform to the dimensional requirements in appendix c., 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). BS 970 EN48A is defined under British Standards (BS), originating from United Kingdom, while IS 3195 52Cr4Mo2V is defined under Bureau of Indian Standards (IS), originating from India.

As per chemical composition, BS 970 EN48A vs IS 3195 52Cr4Mo2V is a 59.7% 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%.
