Strong Match — 98.6% match
based on chemical composition and mechanical property overlap.
IS 6911 X04Cr18Ni10Nb (IS 6911:1992) and EN 10088-1 X6CrNiNb18-10 (EN 10088-1:2014) are both steel grades.
Both fall under the Stainless Steel category.
IS 6911 X04Cr18Ni10Nb is defined under Bureau of Indian Standards (IS), originating from India, while EN 10088-1 X6CrNiNb18-10 is defined under European Standard (EN), originating from Europe.
As per chemical composition, IS 6911 X04Cr18Ni10Nb vs EN 10088-1 X6CrNiNb18-10 is a 98.6% 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 98.6%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
