ASTM A959 304N vs JIS G4305 SUS304

Strong Match — 93.1% match based on chemical composition and mechanical property overlap.

ASTM A959 304N (ASTM A959:2011) and JIS G4305 SUS304 (JIS G4305:2012) are both steel grades. Both fall under the Stainless Steel category. ASTM A959 304N is typically used for wrought stainless steel products; recommended composition limits for adoption by product standards (clause 1.1), while JIS G4305 SUS304 is commonly used for cold-rolled stainless steel plates, sheet and strip. ASTM A959 304N is defined under ASTM International, originating from United States, while JIS G4305 SUS304 is defined under Japanese Industrial Standards (JIS), originating from Japan.

As per chemical composition, ASTM A959 304N vs JIS G4305 SUS304 is a 93.1% 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 93.1%.
