If you are looking for standard-compliant Hot-rolled S30408 NO.1 stainless steel plates for industrial or engineering projects requiring high strength, corrosion resistance, and reliable supply, we can provide you with a comprehensive solution with a full range of specifications and controlled quality.
Our high-quality S30408 stainless steel plates are equivalent to the internationally recognized 304 austenitic stainless steel. Produced through hot rolling, solution treatment, and pickling processes, they feature a uniform and clean surface, dense internal structure, and high strength and toughness, making them suitable for secondary processing such as cutting, bending, and welding.
S30408 hot-rolled stainless steel plates contain 18–20% chromium and 8–10% nickel, possessing excellent corrosion resistance, oxidation resistance, and good mechanical properties. At room temperature, the yield strength reaches 205–310 MPa, tensile strength 520–750 MPa, and elongation ≥40%. They are widely used in chemical equipment, food machinery, storage tanks, building curtain walls, pipelines, and pressure vessel manufacturing.
We strictly adhere to international standards such as GB/T 4237, ASTM A240, and EN 10088. All plates undergo chemical composition analysis, mechanical performance testing, and surface quality inspection to ensure that the dimensional tolerances, flatness, and surface defects of each batch meet the standard requirements.

What is the difference between S30408 and 304 stainless steel?
S30408 and 304 stainless steel are essentially the same material, with the primary difference being the standard/designation system. S30408 is the Chinese GB/T 20878 national standard designation equivalent to AISI 304, focusing on pressure equipment compliance, while "304" refers to the broader ASTM/AISI standards.
