Stainless Steel Coils

Stainless steel coils can be divided into cold-rolled strips, hot-rolled strips, thin silicon steel strips, structural steel strips, and so on. The cold rolled strip in the stainless steel coil is a special treated stainless steel coil product. It is another pair of industrial stainless steel coil products made of stainless steel coils and strips as the basic raw materials and processed by cold rolling mills at room temperature. In most cases, the production of cold rolled strip cannot exceed this range. Otherwise, it will affect many states when used. Cold-rolled strip steel has the characteristics of smooth surface, high dimensional accuracy and good mechanical properties. It is usually processed into coils and coated steel sheets. Cold rolled strip is widely used in tractor, automobile and other industries. Hot rolled strip is another type of stainless steel coil with thicknesses ranging from 1.80 mm to 6.00 mm and widths ranging from 50 mm to 1200 mm. Hot rolled strip is another type of stainless steel coil strip processed by hot rolling mills. It has the advantages of low hardness, easy processing and good ductility, and is often used as a thin plate. The silicon steel strip is another kind of stainless steel coil with the corresponding grain orientation structure, which is often used in the production of various power transformers, pulse transformer converters and other industrial electrical equipment with operating frequencies above 400Hz. Finally, there is the structural steel strip. The structural steel strip in the stainless steel coil has a very large range of use and a large amount of use. For example, it is widely used in heavy industries such as automobile manufacturing, aviation, and aerospace.

Production Paramter

Production Applications

1. Vehicle/Automotive Industry
This is the fastest growing stainless steel coil application field. The use of high-strength stainless steel coils to manufacture vehicle body structures can greatly reduce the weight of the vehicle and enhance the strength of the vehicle body structure. Using stainless steel coils as vehicle panels and decorative components can reduce maintenance costs. In addition, stainless steel coils are also used in automobile exhaust systems due to their advantages of resistance to chloride ion corrosion and heat resistance.
2. Water Industry
The problem of water pollution during its storage and transportation has been paid more and more attention by people. A large number of practices have proved that stainless steel coil is the best choice for water industry such as water preparation, storage, transportation, purification, regeneration, and seawater desalination. Its advantages are: corrosion resistance, earthquake resistance, water saving, sanitation (no rust and copper green), light weight (1/3 reduction), less maintenance, long life (40 years of use), low life cycle cost (LCC) , It is a green and environmentally friendly material that can be recycled and reused.
3. Construction Industry
It is one of the earliest fields of stainless steel coil application. In terms of architectural decoration, at present, stainless steel coils are mainly used in the cladding of exterior walls, interiors and exterior columns of high-rise buildings, as well as interior and exterior decorations and components such as handrails, floors, elevator siding, doors and windows, and curtain walls. The surface-treated, colored and plated stainless steel coil solves the problem of fingerprints after being touched, and further expands the application range of stainless steel coil.
4. Home appliance industry
In the home appliance industry, the most used stainless steel coils are the inner drum of automatic washing machines, the inner tank of water heaters, the inner and outer shells of microwave ovens, and the lining of refrigerators, and ferritic stainless steel coils are mostly used.
5. Environmental protection industry
Industrial waste gas, garbage and sewage treatment plants need to be made of stainless steel coils. In the process of flue gas desulfurization, in order to resist the corrosion of sulfur dioxide, chloride ions and iron ions, it is necessary to use duplex stainless steel coils and high-grade austenitic stainless steel coils in absorption towers, coolers, pumps, valves, flues, etc. . Waste incinerators, wastewater treatment and other facilities need to be made of high-performance stainless steel coil materials.
6. Industrial facilities
The proportion of stainless steel coils used in industrial facilities in developed countries can generally reach 15%-20%, and the current domestic application proportion is still small. On the one hand, it is due to the introduction of complete sets of industrial equipment, and the stainless steel coil material has not been counted, and on the other hand, the domestic material has not been adopted. Chemical, petrochemical, chemical fiber, paper, food, medicine, energy (nuclear power, thermal power, fuel cells) and other fields all require stainless steel coils.
