Related Material — 69.9% match
based on chemical composition and mechanical property overlap.
IS 6603 X12Cr13S (IS 6603:2024) and ASTM A959 XM-34 (ASTM A959:2011) are both steel grades.
Both fall under the Stainless Steel category.
IS 6603 X12Cr13S is typically used for general purposes, semi-finished products, bars, wire rods and bright bars, while ASTM A959 XM-34 is commonly used for wrought stainless steel products; recommended composition limits for adoption by product standards (clause 1.1).
IS 6603 X12Cr13S is defined under Bureau of Indian Standards (IS), originating from India, while ASTM A959 XM-34 is defined under ASTM International, originating from United States.
As per chemical composition, IS 6603 X12Cr13S vs ASTM A959 XM-34 is a 72.8% 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.
