JIS G4304 SUS403 vs ASTM A959 .-

Minimal Match — 35% match based on chemical composition and mechanical property overlap.

JIS G4304 SUS403 (JIS G4304:2021) and ASTM A959 .- (ASTM A959:2011) are both steel grades. Both fall under the Stainless Steel category. JIS G4304 SUS403 is typically used for hot-rolled stainless steel plates and strips, while ASTM A959 .- is commonly used for wrought stainless steel products; recommended composition limits for adoption by product standards (clause 1.1). JIS G4304 SUS403 is defined under Japanese Industrial Standards (JIS), originating from Japan, while ASTM A959 .- is defined under ASTM International, originating from United States.

As per chemical composition, JIS G4304 SUS403 vs ASTM A959 .- is a 73.1% match. Mechanical property data is not available for both grades, so this factor could not be scored. Combined, this makes them a minimal match overall at 35%.
