Minimal Match — 35% match
based on chemical composition and mechanical property overlap.
IS 6911 X04Cr18Ni10Nb (IS 6911:1992) and EN 10088-1 1.4401 (EN 10088-1:2014) are both steel grades.
Both fall under the Stainless Steel category.
IS 6911 X04Cr18Ni10Nb is typically used for stainless and heat-resisting steel plate, sheet and strip (clause 1.1), while EN 10088-1 1.4401 is commonly used for marine, chemical processing, pharmaceutical equipment.
IS 6911 X04Cr18Ni10Nb is defined under Bureau of Indian Standards (IS), originating from India, while EN 10088-1 1.4401 is defined under European Standard (EN), originating from Europe.
As per chemical composition, IS 6911 X04Cr18Ni10Nb vs EN 10088-1 1.4401 is a 67.6% match.
As per mechanical properties, the match is 25%.
Combined, this makes them a minimal match overall at 35%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
