Strong Match — 100% match
based on chemical composition and mechanical property overlap.
ASTM A959 N08367 (ASTM A959:2011) and ASTM A240/A240M N08367 (ASTM A240/A240M:2025) are both steel grades.
Both fall under the Stainless Steel category.
ASTM A959 N08367 is typically used for wrought stainless steel products; recommended composition limits for adoption by product standards (clause 1.1), while ASTM A240/A240M N08367 is commonly used for pressure vessels and general applications (plate, sheet and strip).
ASTM A959 N08367 is defined under ASTM International, originating from United States, while ASTM A240/A240M N08367 is defined under ASTM International, originating from United States.
As per chemical composition, ASTM A959 N08367 vs ASTM A240/A240M N08367 is a 100% 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 100%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
