IS 6603 X02Cr18TiNb vs ASTM A959 .-

Minimal Match — 35% match based on chemical composition and mechanical property overlap.

IS 6603 X02Cr18TiNb (IS 6603:2024) and ASTM A959 .- (ASTM A959:2011) are both steel grades. Both fall under the Stainless Steel category. IS 6603 X02Cr18TiNb is typically used for general purposes, semi-finished products, bars, wire rods and bright bars, while ASTM A959 .- is commonly used for wrought stainless steel products; recommended composition limits for adoption by product standards (clause 1.1). IS 6603 X02Cr18TiNb is defined under Bureau of Indian Standards (IS), originating from India, while ASTM A959 .- is defined under ASTM International, originating from United States.

As per chemical composition, IS 6603 X02Cr18TiNb vs ASTM A959 .- is a 73.5% match. Mechanical property data is not available for both grades, so this factor could not be scored. Combined, this makes them a minimal match overall at 35%.
