SUS 304 316L Stainless Steel Hot Rolled Coil 310S 310Si2 Stainless Steel Sheet Metal Roll

The core value of 300 series (e.g., 304, 316L) hot-rolled No.1 lies in its economic efficiency as a high-value-added intermediate billet and its excellent corrosion resistance and high-temperature resistance, making it ideal for direct application in structural components.

• As a billet for subsequent cold-rolled finishing: This is its largest application and offers the highest cost-effectiveness. Hot-rolled No.1 coils are the source material for producing all cold-rolled products (such as 2B, BA, 8K mirror finish, and various brushed surfaces).
• Industrial pickled sheet (HRAP) raw material: Directly pickling the surface of No.1 yields a clean, uniform, silvery-white hot-rolled pickled sheet, suitable for direct applications where surface finish requirements are not high.
• Direct use in structural components requiring corrosion resistance and strength: This fully utilizes the corrosion resistance, oxidation resistance, and high strength of 300 series stainless steel while accepting its rough appearance to reduce costs.

• High-Temperature and Corrosive Environments: Chemical industry (reaction towers, storage tanks, heat exchangers, pipelines), energy and environmental protection (FGD units, boiler components, hot air ducts), oil extraction (downhole equipment, valve components resistant to chloride ion corrosion)
• Load-Bearing and Structural Applications: Equipment frames, platforms, and tanks used in industries with high hygiene requirements (food and medicals), concealed structural components in construction
• Specific Industrial Products: Hot-end components of automotive exhaust systems (manifolds)
