Stainless steel plates are widely used in all walks of life. 1. Environmental protection industry Industrial waste gas, garbage and sewage treatment devices need to be made of stainless steel plates. In the flue gas desulfurization process, in order to resist the corrosion of sulfur dioxide, chloride ions and iron ions, duplex stainless steel plates and high-grade austenitic stainless steel plates are required in absorption towers, coolers, pumps, valves, flues, etc. Garbage incinerators, waste water treatment and other facilities need to be made of high-performance stainless steel plate materials. 2. Construction industry It is one of the earliest fields where stainless steel plates are applied. In terms of architectural decoration, at present, stainless steel plates are mainly used in the cladding of exterior walls, interior and exterior columns of high-rise buildings, handrails, floors, elevator wall panels, doors and windows, curtain walls and other interior and exterior decorations and components. The surface-treated, colored and plated stainless steel plate solves the problems of easy fingerprints after touching, and further expands the application range of stainless steel plate. 3. Automobile industry This is the fastest growing stainless steel plate application field. The use of high-strength stainless steel plates to manufacture the car body structure can greatly reduce the vehicle's dead weight and enhance the strength of the car body structure. Using stainless steel plates to make vehicle panels and decorative parts can reduce maintenance costs.
