Close Alternative — 77.2% match
based on chemical composition and mechanical property overlap.
ASTM A959 XM-1 (ASTM A959:2011) and JIS G4305 SUS304J2 (JIS G4305:2012) are both steel grades.
Both fall under the Stainless Steel category.
ASTM A959 XM-1 is typically used for wrought stainless steel products; recommended composition limits for adoption by product standards (clause 1.1), while JIS G4305 SUS304J2 is commonly used for cold-rolled stainless steel plates, sheet and strip.
ASTM A959 XM-1 is defined under ASTM International, originating from United States, while JIS G4305 SUS304J2 is defined under Japanese Industrial Standards (JIS), originating from Japan.
As per chemical composition, ASTM A959 XM-1 vs JIS G4305 SUS304J2 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.
