Close Alternative — 84.9% match
based on chemical composition and mechanical property overlap.
EN 10088-1 X65Cr13 (EN 10088-1:2023) and IS 6603 X40Cr13 (IS 6603:2024) are both steel grades.
Both fall under the Stainless Steel category.
EN 10088-1 X65Cr13 is defined under European Standard (EN), originating from Europe, while IS 6603 X40Cr13 is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, EN 10088-1 X65Cr13 vs IS 6603 X40Cr13 is a 88.4% 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 84.9%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
