Close Alternative — 74.9% match
based on chemical composition and mechanical property overlap.
ASTM A959 S30615 (ASTM A959:2011) and JIS G4304 SUSXM15J1 (JIS G4304:2021) are both steel grades.
Both fall under the Stainless Steel category.
ASTM A959 S30615 is typically used for wrought stainless steel products; recommended composition limits for adoption by product standards (clause 1.1), while JIS G4304 SUSXM15J1 is commonly used for hot-rolled stainless steel plates and strips.
ASTM A959 S30615 is defined under ASTM International, originating from United States, while JIS G4304 SUSXM15J1 is defined under Japanese Industrial Standards (JIS), originating from Japan.
As per chemical composition, ASTM A959 S30615 vs JIS G4304 SUSXM15J1 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.
