Strong Match — 87.1% match
based on chemical composition and mechanical property overlap.
IS 6603 X02Cr23Ni4N (IS 6603:2024) and ASTM A240/A240M S32304 (ASTM A240/A240M:2025) are both steel grades.
Both fall under the Stainless Steel category.
IS 6603 X02Cr23Ni4N is typically used for general purposes, semi-finished products, bars, wire rods and bright bars, while ASTM A240/A240M S32304 is commonly used for pressure vessels and general applications (plate, sheet and strip).
IS 6603 X02Cr23Ni4N is defined under Bureau of Indian Standards (IS), originating from India, while ASTM A240/A240M S32304 is defined under ASTM International, originating from United States.
As per chemical composition, IS 6603 X02Cr23Ni4N vs ASTM A240/A240M S32304 is a 93.1% match.
As per mechanical properties, the match is 75%.
Combined, this makes them a strong match overall at 87.1%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
