Strong Match — 89.2% match
based on chemical composition and mechanical property overlap.
EN 10088-1 X12CrNi23-13 (EN 10088-1:2023) and ASTM A959 309S (ASTM A959:2011) are both steel grades.
Both fall under the Stainless Steel category.
EN 10088-1 X12CrNi23-13 is defined under European Standard (EN), originating from Europe, while ASTM A959 309S is defined under ASTM International, originating from United States.
As per chemical composition, EN 10088-1 X12CrNi23-13 vs ASTM A959 309S is a 89.2% 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 89.2%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
