What is JIS G4305 material?
JIS G4305 is a Japanese Industrial Standard (JIS) that specifies the requirements for cold-rolled stainless steel plates, sheets, and strips. This standard explicitly defines the chemical composition, mechanical properties, dimensional tolerances, and surface finishes for various grades of austenitic, ferritic, and martensitic stainless steels. The cold-rolling process not only removes rolling scale and imparts a smooth surface finish to the steel, but also enables stricter control over thickness tolerances and enhances the material's hardness.
JIS G4305 SUS316 Stainless Steel Plate Supplier
JIS G4305 SUS316 stainless steel cold rolled sheet is an austenitic stainless steel plate manufactured in accordance with Japanese Industrial Standards (JIS). It offers excellent corrosion resistance, high surface finish quality, and good cold-forming performance, making it widely used in industrial and architectural applications that require high material purity and corrosion resistance.
SUS316 stainless steel contains approximately 16–18% chromium (Cr), 10–14% nickel (Ni), and 2–3% molybdenum (Mo). The addition of molybdenum significantly improves its resistance to pitting corrosion and crevice corrosion in chloride-containing environments, making it suitable for marine engineering, chemical processing, food processing, and other medium-to-high corrosion environments.
Common surface finishes for SUS316 stainless steel sheets include 2B (bright cold rolled finish), BA (bright annealed finish), and HL (hairline finish). The typical thickness range is 0.3–6.0 mm, with widths available up to 1500–2000 mm. Lengths can be customized according to customer requirements. The standard delivery condition is usually solution annealed, pickled, and cold rolled, ensuring a uniform microstructure and stable mechanical properties.

What is the thickness range for SUS316 under JIS G4305?
JIS G4305 specifically covers cold-rolled products. The thickness typically ranges from 0.3 mm to 6.0 mm. For plates thicker than 6.0 mm, they are usually processed under JIS G4304 (Hot-rolled).

What is the difference between JIS G4305 SUS316 and ASTM A240 316?
In terms of their chromium (Cr), nickel (Ni), and molybdenum (Mo) content, they are chemically equivalent. The primary differences lie in dimensional tolerances (JIS employs metric units, while ASTM utilizes both imperial and metric units) and the sampling methods for mechanical property testing. Furthermore, JIS standards tend to impose stricter requirements regarding the surface quality consistency of cold-rolled products.
Applications of SUS 316 Cold-Rolled Stainless Steel Sheets:
Marine Environments and Marine Fittings,
Chemical Processing and Pharmaceutical Equipment,
Food Processing and Brewing Equipment,
Medical Implants and Surgical Instruments,
Heat Exchangers and Coastal Architectural Panels.
SUS316 Cold-Rolled Stainless Steel Sheet Price
