Close Alternative — 79% match
based on chemical composition and mechanical property overlap.
EN 10088-1 X1CrNb15 (EN 10088-1:2014) and IS 6603 X03Cr17Nb (IS 6603:2024) are both steel grades.
Both fall under the Stainless Steel category.
EN 10088-1 X1CrNb15 is defined under European Standard (EN), originating from Europe, while IS 6603 X03Cr17Nb is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, EN 10088-1 X1CrNb15 vs IS 6603 X03Cr17Nb is a 79% 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 79%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
