Strong Match — 93.1% match
based on chemical composition and mechanical property overlap.
ASTM A959 305 (ASTM A959:2011) and EN 10088-3 X4CrNi18-12 (EN 10088-3:2014) are both steel grades.
Both fall under the Stainless Steel category.
ASTM A959 305 is typically used for wrought stainless steel products; recommended composition limits for adoption by product standards (clause 1.1), while EN 10088-3 X4CrNi18-12 is commonly used for general purposes, semi-finished products, bars, rods, wire, sections and bright products.
ASTM A959 305 is defined under ASTM International, originating from United States, while EN 10088-3 X4CrNi18-12 is defined under European Standard (EN), originating from Europe.
As per chemical composition, ASTM A959 305 vs EN 10088-3 X4CrNi18-12 is a 93.1% 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 93.1%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
