From the perspective of the industrial composition of stainless steel consumption, the automotive industry is currently the fastest growing stainless steel application field, and the home appliance industry is a potential big market for stainless steel applications. In addition, the demand for stainless steel in the water industry, building and structural industry, environmental protection industry, and industrial facilities will also increase year by year.
 
Specifically:
 
Vehicle/Automotive Industry: This is currently the fastest growing stainless steel application field. Using high-strength stainless steel to make the car body structure can greatly reduce the weight of the vehicle and enhance the strength of the car body structure. Using stainless steel as the vehicle panel and decorative parts can reduce maintenance costs.
 
Water industry: The problem of water being polluted during its storage and transportation has been paid more and more attention. A lot of practice has proved that stainless steel is the best material for the 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 weight reduction), less maintenance, long life (40 years of use), life cycle cost (LCC) Low, environmentally friendly materials that can be recycled and reused.
 
Construction industry: It is one of the earliest fields of application of stainless steel. In the field of architectural decoration, stainless steel is currently mainly used for the outer wall, interior and outer column coating of high-rise buildings, handrails, floors, elevator siding, doors, windows, curtain walls, etc. The interior and exterior decoration and components are made of stainless steel plates with surface treatment, coloring and plating, which solves the problem of easy fingerprints after touching, and further expands the application range of stainless steel.
 
Home appliance industry: In the home appliance industry, the large amount of stainless steel is the inner cylinder of the automatic washing machine, the inner tank of the water heater, the outer shell of the microwave oven, and the inner lining of the refrigerator, and the ferrite stainless steel is mostly used.
 
Environmental protection industry: Industrial waste gas, garbage and sewage treatment devices need to be made of stainless steel. In the flue gas desulfurization process, in order to resist the corrosion of sulfur dioxide, chloride ions, and iron ions, duplex stainless steel and high-grade austenitic stainless steel need to be used in absorption towers, coolers, pumps, valves, and flues. Facilities such as waste incinerators and wastewater treatment need to be made of high-performance stainless steel.
 
Industrial facilities: The proportion of stainless steel used in industrial facilities in developed countries is generally 15%-20%. The current domestic application rate is still very small. This is due to the introduction of complete sets of industrial equipment. Stainless steel materials are not counted. Because domestic materials have not been adopted. Stainless steel is needed in the chemical, petrochemical, chemical fiber, paper, food, medicine, energy (nuclear power, thermal power, fuel cell) and other fields.
 
In addition, the existing imported equipment has entered the maintenance period. With the improvement of the quality of domestic stainless steel products and the development of special brand products, the application of stainless steel in domestic industrial facilities will increase year by year.
