Close Alternative — 83.1% match
based on chemical composition and mechanical property overlap.
IS 6603 X04Cr17 (IS 6603:2024) and EN 10088-1 X10CrAlSi18 (EN 10088-1:2014) are both steel grades.
Both fall under the Stainless Steel category.
IS 6603 X04Cr17 is defined under Bureau of Indian Standards (IS), originating from India, while EN 10088-1 X10CrAlSi18 is defined under European Standard (EN), originating from Europe.
As per chemical composition, IS 6603 X04Cr17 vs EN 10088-1 X10CrAlSi18 is a 83.1% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a close alternative overall at 83.1%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
