Close Alternative — 74.9% match
based on chemical composition and mechanical property overlap.
ASTM A240/A240M S32101 (ASTM A240/A240M:2025) and ASTM A959 S32001 (ASTM A959:2011) are both steel grades.
Both fall under the Stainless Steel category.
ASTM A240/A240M S32101 is typically used for pressure vessels and general applications (plate, sheet and strip), while ASTM A959 S32001 is commonly used for wrought stainless steel products; recommended composition limits for adoption by product standards (clause 1.1).
ASTM A240/A240M S32101 is defined under ASTM International, originating from United States, while ASTM A959 S32001 is defined under ASTM International, originating from United States.
As per chemical composition, ASTM A240/A240M S32101 vs ASTM A959 S32001 is a 74.9% 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 74.9%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
