Close Alternative — 76.4% match
based on chemical composition and mechanical property overlap.
EN 10088-1 X14CrMoS17 (EN 10088-1:2023) and ASTM A959 434 (ASTM A959:2011) are both steel grades.
Both fall under the Stainless Steel category.
EN 10088-1 X14CrMoS17 is defined under European Standard (EN), originating from Europe, while ASTM A959 434 is defined under ASTM International, originating from United States.
As per chemical composition, EN 10088-1 X14CrMoS17 vs ASTM A959 434 is a 76.4% 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 76.4%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
