Close Alternative — 81.5% match
based on chemical composition and mechanical property overlap.
ASTM A276/A276M S31803 (ASTM A276/A276M:2017) and IS 6603 X02Cr22Ni5Mo3N (IS 6603:2024) are both steel grades.
Both fall under the Stainless Steel category.
ASTM A276/A276M S31803 is typically used for stainless steel bars and shapes (hot-finished or cold-finished), while IS 6603 X02Cr22Ni5Mo3N is commonly used for general purposes, semi-finished products, bars, wire rods and bright bars.
ASTM A276/A276M S31803 is defined under ASTM International, originating from United States, while IS 6603 X02Cr22Ni5Mo3N is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, ASTM A276/A276M S31803 vs IS 6603 X02Cr22Ni5Mo3N is a 97.3% match.
As per mechanical properties, the match is 50%.
Combined, this makes them a close alternative overall at 81.5%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
