Strong Match — 94.5% match
based on chemical composition and mechanical property overlap.
IS 6911 X04Cr19Ni9 (IS 6911:1992) and ASTM A959 SS304 (ASTM A959:2011) are both steel grades.
Both fall under the Stainless Steel category.
IS 6911 X04Cr19Ni9 is typically used for used in food equipment, chemical processing units, kitchenware, tanks, piping, and architectural applications., while ASTM A959 SS304 is commonly used for food processing, chemical equipment, kitchen equipment.
IS 6911 X04Cr19Ni9 is defined under Bureau of Indian Standards (IS), originating from India, while ASTM A959 SS304 is defined under ASTM International, originating from United States.
As per chemical composition, IS 6911 X04Cr19Ni9 vs ASTM A959 SS304 is a 94.5% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a strong match overall at 94.5%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
