Strong Match — 86.7% match
based on chemical composition and mechanical property overlap.
IS 6911 X20Cr25Ni20 (IS 6911:1992) and EN 10088-1 X15CrNiSi25-21 (EN 10088-1:2023) are both steel grades.
Both fall under the Stainless Steel category.
IS 6911 X20Cr25Ni20 is defined under Bureau of Indian Standards (IS), originating from India, while EN 10088-1 X15CrNiSi25-21 is defined under European Standard (EN), originating from Europe.
As per chemical composition, IS 6911 X20Cr25Ni20 vs EN 10088-1 X15CrNiSi25-21 is a 86.7% 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 86.7%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
