IS 6603 X02Cr19Ni11 vs BS 970 (Part 1) 304S11

Strong Match — 88.9% match based on chemical composition and mechanical property overlap.

IS 6603 X02Cr19Ni11 (IS 6603:2024) and BS 970 (Part 1) 304S11 (BS 970 (Part 1):1983) are both steel grades. Both fall under the Stainless Steel category. IS 6603 X02Cr19Ni11 is typically used for general purposes, semi-finished products, bars, wire rods and bright bars, while BS 970 (Part 1) 304S11 is commonly used for austenitic stainless and heat resisting steel for mechanical and allied engineering purposes (table 14, with table 15 for the cold drawn condition).. IS 6603 X02Cr19Ni11 is defined under Bureau of Indian Standards (IS), originating from India, while BS 970 (Part 1) 304S11 is defined under British Standards (BS), originating from United Kingdom.

As per chemical composition, IS 6603 X02Cr19Ni11 vs BS 970 (Part 1) 304S11 is a 88.9% match. Mechanical property data is not available for both grades, so this factor could not be scored. Combined, this makes them a strong match overall at 88.9%.
