IS 11169 (Part 2) X02Cr18Ni9Cu3 vs BS 970 (Part 3) 304S11
Strong Match — 87.6% match
based on chemical composition and mechanical property overlap.
IS 11169 (Part 2) X02Cr18Ni9Cu3 (IS 11169 (Part 2):2023) and BS 970 (Part 3) 304S11 (BS 970 (Part 3):1991) are both steel grades.
Both fall under the Stainless Steel category.
IS 11169 (Part 2) X02Cr18Ni9Cu3 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 3) 304S11 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) X02Cr18Ni9Cu3 is defined under Bureau of Indian Standards (IS), originating from India, while BS 970 (Part 3) 304S11 is defined under British Standards (BS), originating from United Kingdom.
As per chemical composition, IS 11169 (Part 2) X02Cr18Ni9Cu3 vs BS 970 (Part 3) 304S11 is a 87.6% 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 87.6%.
Frequently Compared With IS 11169 (Part 2) X02Cr18Ni9Cu3:
