Close Alternative — 81% match
based on chemical composition and mechanical property overlap.
EN 10088-2 X2CrAlSiNb18 (EN 10088-2:2014) and EN 10088-1 X2CrTi21 (EN 10088-1:2023) are both steel grades.
Both fall under the Stainless Steel category.
EN 10088-2 X2CrAlSiNb18 is defined under European Standard (EN), originating from Europe, while EN 10088-1 X2CrTi21 is defined under European Standard (EN), originating from Europe.
As per chemical composition, EN 10088-2 X2CrAlSiNb18 vs EN 10088-1 X2CrTi21 is a 81% match.
Mechanical property data is not available for both grades, so this factor could not be scored.
Combined, this makes them a close alternative overall at 81%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
