Strong Match — 100% match
based on chemical composition and mechanical property overlap.
ASTM A276/A276M S31700 (ASTM A276/A276M:2017) and IS 6603 X04Cr18Ni12Mo3 (IS 6603:2024) are both steel grades.
Both fall under the Stainless Steel category.
ASTM A276/A276M S31700 is typically used for stainless steel bars and shapes (hot-finished or cold-finished), while IS 6603 X04Cr18Ni12Mo3 is commonly used for general purposes, semi-finished products, bars, wire rods and bright bars.
ASTM A276/A276M S31700 is defined under ASTM International, originating from United States, while IS 6603 X04Cr18Ni12Mo3 is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, ASTM A276/A276M S31700 vs IS 6603 X04Cr18Ni12Mo3 is a 100% match.
As per mechanical properties, the match is 100%.
Combined, this makes them a strong match overall at 100%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
