Close Alternative — 80% match
based on chemical composition and mechanical property overlap.
IS 6603 X01Ni25Cr20Mo5Cu (IS 6603:2024) and ASTM A959 N08700 (ASTM A959:2011) are both steel grades.
Both fall under the Stainless Steel category.
IS 6603 X01Ni25Cr20Mo5Cu is typically used for general purposes, semi-finished products, bars, wire rods and bright bars, while ASTM A959 N08700 is commonly used for wrought stainless steel products; recommended composition limits for adoption by product standards (clause 1.1).
IS 6603 X01Ni25Cr20Mo5Cu is defined under Bureau of Indian Standards (IS), originating from India, while ASTM A959 N08700 is defined under ASTM International, originating from United States.
As per chemical composition, IS 6603 X01Ni25Cr20Mo5Cu vs ASTM A959 N08700 is a 80% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a close alternative overall at 80%.
Frequently Compared With IS 6603 X01Ni25Cr20Mo5Cu:
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
