Strong Match — 88.8% match
based on chemical composition and mechanical property overlap.
IS 6603 X13Mn13Cr18N (IS 6603:2024) and ASTM A276/A276M S24000 (ASTM A276/A276M:2017) are both steel grades.
Both fall under the Stainless Steel category.
IS 6603 X13Mn13Cr18N is typically used for general purposes, semi-finished products, bars, wire rods and bright bars, while ASTM A276/A276M S24000 is commonly used for stainless steel bars and shapes (hot-finished or cold-finished).
IS 6603 X13Mn13Cr18N is defined under Bureau of Indian Standards (IS), originating from India, while ASTM A276/A276M S24000 is defined under ASTM International, originating from United States.
As per chemical composition, IS 6603 X13Mn13Cr18N vs ASTM A276/A276M S24000 is a 83.2% match.
As per mechanical properties, the match is 100%.
Combined, this makes them a strong match overall at 88.8%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
