Strong Match — 87.3% match
based on chemical composition and mechanical property overlap.
ASTM A959 S31002 (ASTM A959:2011) and EN 10088-1 X1CrNi25-21 (EN 10088-1:2023) are both steel grades.
Both fall under the Stainless Steel category.
ASTM A959 S31002 is defined under ASTM International, originating from United States, while EN 10088-1 X1CrNi25-21 is defined under European Standard (EN), originating from Europe.
As per chemical composition, ASTM A959 S31002 vs EN 10088-1 X1CrNi25-21 is a 87.3% 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 87.3%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
