ASTM A959 .- vs JIS G4304 SUS430LX

Close Alternative — 84.4% match based on chemical composition and mechanical property overlap.

ASTM A959 .- (ASTM A959:2011) and JIS G4304 SUS430LX (JIS G4304:2021) are both steel grades. Both fall under the Stainless Steel category. ASTM A959 .- is typically used for wrought stainless steel products; recommended composition limits for adoption by product standards (clause 1.1), while JIS G4304 SUS430LX is commonly used for hot-rolled stainless steel plates and strips. ASTM A959 .- is defined under ASTM International, originating from United States, while JIS G4304 SUS430LX is defined under Japanese Industrial Standards (JIS), originating from Japan.

As per chemical composition, ASTM A959 .- vs JIS G4304 SUS430LX is a 84.4% 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 84.4%.
