Strong Match — 87.5% match
based on chemical composition and mechanical property overlap.
EN 10088-1 X6CrNi17-1 (EN 10088-1:2023) and ASTM A240/A240M S43000 (ASTM A240/A240M:2025) are both steel grades.
Both fall under the Stainless Steel category.
EN 10088-1 X6CrNi17-1 is defined under European Standard (EN), originating from Europe, while ASTM A240/A240M S43000 is defined under ASTM International, originating from United States.
As per chemical composition, EN 10088-1 X6CrNi17-1 vs ASTM A240/A240M S43000 is a 87.5% 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 87.5%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
