Related Material — 69.9% match
based on chemical composition and mechanical property overlap.
ASTM A959 S20162 (ASTM A959:2011) and IS 6603 X15Cr18Ni8 (IS 6603:2024) are both steel grades.
Both fall under the Stainless Steel category.
ASTM A959 S20162 is typically used for wrought stainless steel products; recommended composition limits for adoption by product standards (clause 1.1), while IS 6603 X15Cr18Ni8 is commonly used for general purposes, semi-finished products, bars, wire rods and bright bars.
ASTM A959 S20162 is defined under ASTM International, originating from United States, while IS 6603 X15Cr18Ni8 is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, ASTM A959 S20162 vs IS 6603 X15Cr18Ni8 is a 70.9% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a related material overall at 69.9%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
