Close Alternative — 75% match
based on chemical composition and mechanical property overlap.
EN 10088-1 1.4401 (EN 10088-1:2014) and ASTM A959 316L (ASTM A959:2011) are both steel grades.
Both fall under the Stainless Steel category.
EN 10088-1 1.4401 is typically used for marine, chemical processing, pharmaceutical equipment, while ASTM A959 316L is commonly used for wrought stainless steel products; recommended composition limits for adoption by product standards (clause 1.1).
EN 10088-1 1.4401 is defined under European Standard (EN), originating from Europe, while ASTM A959 316L is defined under ASTM International, originating from United States.
As per chemical composition, EN 10088-1 1.4401 vs ASTM A959 316L is a 75% 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 75%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
