Close Alternative — 82.9% match
based on chemical composition and mechanical property overlap.
JIS G4304 SUS304N2 (JIS G4304:2021) and ASTM A959 SS304 (ASTM A959:2011) are both steel grades.
Both fall under the Stainless Steel category.
JIS G4304 SUS304N2 is typically used for hot-rolled stainless steel plates and strips, while ASTM A959 SS304 is commonly used for food processing, chemical equipment, kitchen equipment.
JIS G4304 SUS304N2 is defined under Japanese Industrial Standards (JIS), originating from Japan, while ASTM A959 SS304 is defined under ASTM International, originating from United States.
As per chemical composition, JIS G4304 SUS304N2 vs ASTM A959 SS304 is a 82.9% 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 82.9%.
Matched by chemical composition and mechanical properties, not a formal equivalence claim. Always verify against the applicable standard before substitution.
