Features
Rough Surface
After hot rolling and pickling to remove oxide scale, the surface exhibits a uniformly rough texture, suitable for subsequent reprocessing steps such as sandblasting, coating, or machining.
High Deformation Capacity
With an elongation of ≥40%, it can withstand significant plastic deformation without cracking during cold bending, rolling, and forming, making it suitable for tank and shell manufacturing.
Corrosion Resistance
Cr (18.0–20.0%) and Ni (8.0–10.5%) form a stable passivation film, slowing down the oxidation process on metal surfaces in general atmospheric and weakly corrosive environments.
Thickness Available
Thickness range 3.0–50.0 mm, coil weight up to 25 MT, meeting the material cross-sectional size requirements of large structural components and heavy-duty equipment.
Applications
Pressure Vessel and Storage Tank Industry
Used in the manufacture of tank shells and outer walls of pressure vessels, bearing the pressure of internal media and environmental effects during service.
Chemical Equipment Manufacturing Industry
Used in reactors, piping, and supporting structural components, serving as a base material for carrying and isolating media.
customized services
Used in equipment bases, frames, and outer shell structures, providing support and connection functions within the overall machine.
Machinery Manufacturing Industry
Used as a base material for subsequent cold rolling, cutting, or surface treatment, for further processing into products of different specifications.
