Strong Match — 88.4% match
based on chemical composition and mechanical property overlap.
IS 6603 X20Cr13 (IS 6603:2024) and ASTM A959 416Se (ASTM A959:2011) are both steel grades.
Both fall under the Stainless Steel category.
IS 6603 X20Cr13 is typically used for general purposes, semi-finished products, bars, wire rods and bright bars, while ASTM A959 416Se is commonly used for wrought stainless steel products; recommended composition limits for adoption by product standards (clause 1.1).
IS 6603 X20Cr13 is defined under Bureau of Indian Standards (IS), originating from India, while ASTM A959 416Se is defined under ASTM International, originating from United States.
As per chemical composition, IS 6603 X20Cr13 vs ASTM A959 416Se is a 88.4% 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 88.4%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
