Strong Match — 100% match
based on chemical composition and mechanical property overlap.
EN 10088-1 X7CrNiAl17-7 (EN 10088-1:2014) and IS 6603 X07Cr17Ni7Al (IS 6603:2024) are both steel grades.
Both fall under the Stainless Steel category.
EN 10088-1 X7CrNiAl17-7 is defined under European Standard (EN), originating from Europe, while IS 6603 X07Cr17Ni7Al is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, EN 10088-1 X7CrNiAl17-7 vs IS 6603 X07Cr17Ni7Al is a 100% 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 100%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
