Close Alternative — 83.4% match
based on chemical composition and mechanical property overlap.
EN 10088-3 X55CrMo14 (EN 10088-3:2014) and EN 10088-1 X50CrMoV15 (EN 10088-1:2023) are both steel grades.
Both fall under the Stainless Steel category.
EN 10088-3 X55CrMo14 is defined under European Standard (EN), originating from Europe, while EN 10088-1 X50CrMoV15 is defined under European Standard (EN), originating from Europe.
As per chemical composition, EN 10088-3 X55CrMo14 vs EN 10088-1 X50CrMoV15 is a 83.4% 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 83.4%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
