IS 11169 (Part 2) X04Cr18Ni10Ti vs BS 970 (Part 1) 321S31

Strong Match — 97.4% match based on chemical composition and mechanical property overlap.

IS 11169 (Part 2) X04Cr18Ni10Ti (IS 11169 (Part 2):2023) and BS 970 (Part 1) 321S31 (BS 970 (Part 1):1983) are both steel grades. Both fall under the Stainless Steel category. IS 11169 (Part 2) X04Cr18Ni10Ti is typically used for cold heading and cold extrusion of stainless steel parts; the standard covers wires, wire rods and bars of 0.8 to 50 mm (clause 1.1, table 11), while BS 970 (Part 1) 321S31 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 11169 (Part 2) X04Cr18Ni10Ti is defined under Bureau of Indian Standards (IS), originating from India, while BS 970 (Part 1) 321S31 is defined under British Standards (BS), originating from United Kingdom.

As per chemical composition, IS 11169 (Part 2) X04Cr18Ni10Ti vs BS 970 (Part 1) 321S31 is a 97.4% 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 97.4%.
