420J1 NO.1 Stainless Hot Rolled Coils

Application:

Applications, from construction to automotive, from transportation to storage, from industrial production to household appliances, basically covering all walks of life. Whether it is stainless steel plate, stainless steel tube or other forms of stainless steel materials, they can be seen in a variety of fields.

Stainless Steel Sheet

Automotive industry

Stainless steel in the automotive industry should be considered a relatively developed area of application of stainless steel sheet. The use of high-strength stainless steel sheet as a raw material for the manufacture of vehicle body structure can greatly reduce the weight of the vehicle, enhance the strength of the overall structure of the vehicle, and if the vehicle panel is made of stainless steel sheet, it can effectively save maintenance costs. In addition, stainless steel plate due to its good resistance to chloride ion corrosion and heat resistance, is used in the production of automotive exhaust systems. European and American countries are using a large number of stainless steel plate as a raw material for automotive production.

Construction industry

Stainless steel coil has a long history of application in the field of construction, and is one of the widely used areas. In construction and home decoration, stainless steel coil is commonly used in the exterior walls of high-rise buildings, indoor and outdoor columns. In addition, there are handrails, elevator wall panels, doors and windows and other internal and external components. In addition, the surface treatment of stainless steel sheets, such as coloring and coating of stainless steel sheets, can solve the problem of easy handprints after touching, improve the decorative aesthetics and further expand the application areas of stainless steel sheets and coils.

Home appliance business

As far as household appliances are concerned, the consumption of stainless steel is also large. Just look at the inner tube of automatic washing machines, the inner tank of water heaters, the inner shell of microwave ovens, the lining of refrigerators, etc., it is necessary to know that household appliances usually use ferritic stainless steel coils as raw materials. In addition, with the growing popularity of real estate and the increasing demand for home appliances, it is surprising to see the same amount of stainless steel coils.

Water Industry

There is now a growing concern about the potential contamination of water during storage and transportation. Practice has shown that stainless steel coils are well suited as raw materials for water production, storage, transportation, purification, regeneration, desalination and other water industry equipment. Its advantages are: corrosion resistance, shock resistance, water conservation, sanitation (no rust and copper green), light weight (1/3 less), low maintenance, long service life (up to 40 years), low life cycle cost (LCC), and a recyclable and green material.

Industrial facilities

The proportion of stainless steel coils used in industrial facilities in developed countries can usually reach 15-20%, and now the proportion of domestic applications is also on the rise. On the one hand, this is due to the introduction of complete sets of industrial equipment, stainless steel coil material has not yet been counted, on the other hand, because domestic materials are also being used. Stainless steel coils are used in chemical, petrochemical, chemical fiber, paper, food, medicine, energy (nuclear power, thermal power, fuel cells) and other fields. With the improvement of the quality of domestic stainless steel coils and the development of special brand products, the future application of stainless steel coils in domestic industrial facilities will increase year by year.

Environmental protection industry

Stainless steel coil is not only used in industrial production, but also used as a raw material for industrial waste gas, waste and sewage treatment devices. In the flue gas desulfurization process, in order to resist the corrosion of sulfur dioxide, chloride ions and iron ions, it is necessary to use duplex stainless steel coils and advanced austenitic stainless steel coils in waste incinerators such as absorption towers, coolers, pumps, valves and flue pipes, and wastewater treatment and other facilities require the use of high-performance stainless steel coils.
