Application of stainless steel coil in several major industries
Jun 05, 2017

From the stainless steel coil application industry analysis, the automotive industry is currently the fastest growing stainless steel coil application field. In the past decade, the consumption of stainless steel coils in Japan has increased from an average of 10 kg to 30 kg, and the United States has more than 40 kilograms. Bus, subway, high-speed railway vehicles and other public transport tools are widely used in stainless steel coil. China's home appliance industry is a potential big market for stainless steel coil applications. In addition, the stainless steel plate in the water industry, construction and structural industry, environmental protection industry, industrial facilities, the demand will also increase year by year.

1. Vehicle/Automobile industry

This is the fastest development of the current stainless steel coil application field. The use of high-strength stainless steel coil plate manufacturing car body structure can greatly reduce vehicle weight, enhance the strength of the body structure, using stainless steel plate to make vehicles panel and decorative parts can reduce maintenance costs. In addition, stainless steel coils are also due to the advantages of chlorine-resistant corrosion and heat resistance because of the automotive exhaust system. Now, Japan, the United States, Sweden and other countries have used a large number of stainless steel plate rolling vehicles. Japan from the 80 's began to promote, at present its stainless steel coil train vehicle has reached 60%. The car industry is the focus of the development of stainless steel coil.

2. The water industry

The problem that water has been polluted during its storage and transportation has been paid more and more attention. A lot of practice has proved that the stainless steel coil plate is the best material for water preparation, storage, transportation, purification, regeneration, seawater desalination and other water industry. Its advantages are: corrosion-resistant, earthquake-resistant, water-saving, health (no rust and copper green), light weight (1/3), less maintenance, long life (can use 40 years), life cycle Cost (LCC) low, is a recyclable reusable green materials. According to the introduction, at present, Japan Tokyo area pipeline stainless steel coil has reached 76%, pipe leakage rate from the original 14.7% to the current 7.5%. After a major earthquake in Osaka, Japan, the stainless steel plate was intact. Recently, the development of corrugated pipe joints in Japan, so that the construction cost of stainless steel coil water pipeline reduced by 20%, the total cost reduced by 3%, maintenance costs reduced by 3/4.

3. Construction

It is one of the earliest applications of stainless steel coils. In the aspect of building decoration, at present, the stainless steel coil is mainly used in the outer walls of high-rise buildings, indoor and outer columns of the cladding, handrails, floors, elevator wall panels, doors and windows, curtain walls and other interior and exterior decoration and components. By surface treatment, coloring, coating of stainless steel coil plate, to solve the touch after the problem of fingerprints, so that the application of stainless steel coil expanded further. Japan has developed a variety of stainless steel sheet roofing materials, such as corrosion-resistance of better high, medium-chromium ferrite and a variety of coating plate. Developed in Sweden, the Super-Clean brushed surface stainless steel coil board, the French Ugine development of the Ugitop table panel, for the construction industry to provide a new choice.

4. Home Appliance Industry

In the home appliance industry, stainless steel plate volume is the automatic washing machine inner cylinder, water heater inside the tank, microwave oven inside and outside the shell, refrigerator liner, and many of the use of ferritic stainless steel coil plate. The proportion of stainless steel coils in western Europe is relatively large, and Asia is generally used less than Japan's near European level. 1999, the Japanese household electrical appliances industry ferrite, martensitic stainless steel coil consumption reached 28%, the austenite accounted for 12%. China's production of microwave ovens, refrigerators, air-conditioning, television and so on has been the world's competitive export products, domestic electrical appliances industry is the potential of stainless steel coil application market. It is estimated that in the next 5-10 years, China's household electrical appliances industry stainless steel coil demand will reach 100,000-150,000 tons.

5. Environmental protection Industry

Industrial waste gas, waste and sewage treatment equipment should be made of stainless steel coil. In the flue gas desulfurization process, in order to resist sulfur dioxide and chloride ions, iron ions corrosion, in the absorber tower, cooler, pumps, valves, flue and other places need to use duplex stainless steel coil plate and high grade austenitic stainless steel coil. Waste incinerator, waste water treatment and other facilities need to use high-performance stainless steel coil material production.

6. Industrial facilities

The proportion of stainless steel coils used in industrial facilities in developed countries is generally 15%-20%, and the domestic application rate is still very small. This is partly due to the introduction of industrial equipment, stainless steel coil materials are not counted, on the other hand because domestic materials have not been adopted. Chemical, petrochemical, chemical fiber, papermaking, food, medicine, energy (nuclear, thermal power, fuel cell) and other fields require stainless steel coil. In addition, the existing import equipment has entered the maintenance period. With the improvement of the quality of domestic stainless steel coil products and the development of special product, the application of stainless steel coil plate will increase yearly in domestic industrial facilities.
