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

SUS 304 316L Stainless Steel Coils , 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.

1. As a billet for subsequent cold-rolled finishing (primary use)

This is its largest application and offers the highest cost-effectiveness.

Cold-rolled raw material: 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). Subsequent processes such as pickling, cold rolling, annealing, and finishing transform it into a high-quality finished product.

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.

2. 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: Shells and structural supports for reaction towers, storage tanks, heat exchangers, and pipelines.

Energy and Environmental Protection: Flue gas desulfurization (FGD) units, boiler components, and hot air ducts.

Oil Extraction: Downhole equipment, valve components, etc., resistant to chloride ion corrosion.

Load-Bearing and Structural Applications:

Equipment frames, platforms, and tanks used in industries with high hygiene requirements, such as food and pharmaceuticals (although not in direct contact with the medium, they must be resistant to environmental corrosion).

Concealed structural components in the construction industry.

Specific Industrial Products:

Hot-end components of automotive exhaust systems (such as manifolds), although ferritic steels such as 409 are more commonly used, 304 is also used in some high-performance models or parts.
