Close Alternative — 81.5% match
based on chemical composition and mechanical property overlap.
ASTM A959 403 (ASTM A959:2011) and EN 10088-1 1.4006 (EN 10088-1:2014) are both steel grades.
Both fall under the Stainless Steel category.
ASTM A959 403 is typically used for wrought stainless steel products; recommended composition limits for adoption by product standards (clause 1.1), while EN 10088-1 1.4006 is commonly used for cutlery, turbine blades, fasteners, surgical instruments.
ASTM A959 403 is defined under ASTM International, originating from United States, while EN 10088-1 1.4006 is defined under European Standard (EN), originating from Europe.
As per chemical composition, ASTM A959 403 vs EN 10088-1 1.4006 is a 81.5% 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 81.5%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
