IS 11169 (Part 2) X04Cr17Ni12Mo2Ti vs BS 970 (Part 3) 320S31

Strong Match — 90.4% match based on chemical composition and mechanical property overlap.

IS 11169 (Part 2) X04Cr17Ni12Mo2Ti (IS 11169 (Part 2):1989) and BS 970 (Part 3) 320S31 (BS 970 (Part 3):1991) are both steel grades. Both fall under the Stainless Steel category. IS 11169 (Part 2) X04Cr17Ni12Mo2Ti is typically used for cold heading and cold extrusion; the standard covers wires, wire rods and bars (clause 1.1), while BS 970 (Part 3) 320S31 is commonly used for bright cold finished bars (cold drawn, turned or precision ground) for general engineering purposes, in straight lengths; austenitic stainless and heat resisting steel (table 18). IS 11169 (Part 2) X04Cr17Ni12Mo2Ti is defined under Bureau of Indian Standards (IS), originating from India, while BS 970 (Part 3) 320S31 is defined under British Standards (BS), originating from United Kingdom.

As per chemical composition, IS 11169 (Part 2) X04Cr17Ni12Mo2Ti vs BS 970 (Part 3) 320S31 is a 90.4% 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 90.4%.
