Strong Match — 88.9% match
based on chemical composition and mechanical property overlap.
EN 10088-3 X2CrNiMo18-15-4 (EN 10088-3:2014) and ASTM A959 317L (ASTM A959:2011) are both steel grades.
Both fall under the Stainless Steel category.
EN 10088-3 X2CrNiMo18-15-4 is typically used for general purposes, semi-finished products, bars, rods, wire, sections and bright products, while ASTM A959 317L is commonly used for wrought stainless steel products; recommended composition limits for adoption by product standards (clause 1.1).
EN 10088-3 X2CrNiMo18-15-4 is defined under European Standard (EN), originating from Europe, while ASTM A959 317L is defined under ASTM International, originating from United States.
As per chemical composition, EN 10088-3 X2CrNiMo18-15-4 vs ASTM A959 317L is a 88.9% 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 88.9%.
