ASTM A959 S30430 vs IS 11169 (Part 2) X02Cr18Ni9Cu3

Strong Match — 91.8% match based on chemical composition and mechanical property overlap.

ASTM A959 S30430 (ASTM A959:2011) and IS 11169 (Part 2) X02Cr18Ni9Cu3 (IS 11169 (Part 2):2023) are both steel grades. Both fall under the Stainless Steel category. ASTM A959 S30430 is typically used for wrought stainless steel products; recommended composition limits for adoption by product standards (clause 1.1), while IS 11169 (Part 2) X02Cr18Ni9Cu3 is commonly 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). ASTM A959 S30430 is defined under ASTM International, originating from United States, while IS 11169 (Part 2) X02Cr18Ni9Cu3 is defined under Bureau of Indian Standards (IS), originating from India.

As per chemical composition, ASTM A959 S30430 vs IS 11169 (Part 2) X02Cr18Ni9Cu3 is a 91.8% 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 91.8%.
