Strong Match — 94.2% match
based on chemical composition and mechanical property overlap.
EN 10088-1 X8CrNi25-21 (EN 10088-1:2014) and IS 6603 X04Cr25Ni20 (IS 6603:2024) are both steel grades.
Both fall under the Stainless Steel category.
EN 10088-1 X8CrNi25-21 is typically used for furnace parts, heat exchangers, kiln furniture, while IS 6603 X04Cr25Ni20 is commonly used for general purposes, semi-finished products, bars, wire rods and bright bars.
EN 10088-1 X8CrNi25-21 is defined under European Standard (EN), originating from Europe, while IS 6603 X04Cr25Ni20 is defined under Bureau of Indian Standards (IS), originating from India.
As per chemical composition, EN 10088-1 X8CrNi25-21 vs IS 6603 X04Cr25Ni20 is a 94.2% 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 94.2%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
