Close Alternative — 77.2% match
based on chemical composition and mechanical property overlap.
ASTM A240/A240M S43600 (ASTM A240/A240M:2025) and EN 10088-1 X6CrMoS17 (EN 10088-1:2014) are both steel grades.
Both fall under the Stainless Steel category.
ASTM A240/A240M S43600 is defined under ASTM International, originating from United States, while EN 10088-1 X6CrMoS17 is defined under European Standard (EN), originating from Europe.
As per chemical composition, ASTM A240/A240M S43600 vs EN 10088-1 X6CrMoS17 is a 77.2% 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 77.2%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
