Application of stainless steel

From the analysis of application of stainless steel industry, stainless steel coil automobile industry is currently the fastest growing application areas. In the past ten years, the Japanese automobile consumption of stainless steel coil has increased from 10 kg to 30 kg, the United States has more than 40 kilograms. Bus, subway, high-speed railway vehicles and other public transportation tools are widely used in stainless steel coil. Chinese stainless steel appliance industry is big potential market applications. In addition, stainless steel demand in the water industry, construction industry, environmental protection, industrial structure and industrial facilities will also be increased year by year.

Vehicle / automotive industry

This is the stainless steel currently the fastest growing application areas of. Using high strength stainless steel body structure can greatly reduce the weight of the vehicle body structure, enhance the strength, with stainless steel panels and decorative parts do vehicle can reduce maintenance costs. In addition, because the stainless steel coil has the advantages of anti chloride corrosion and heat resistance was due to automobile exhaust system. Now, stainless steel has been widely used in Japan, the United States, Sweden and other vehicles in china. Japan from 80s began to promote, the stainless steel train vehicle has reached 60%. The car industry is the key to development of the application of stainless steel coil.

Two, water industry

The problem of water pollution during storage and transportation has been paid more and more attention. Practice has proved that a large number of stainless steel coil is water preparation, storage, transportation, purification, recycling, desalination and other water industry best material. The advantages are: corrosion resistance, earthquake resistance, water saving, sanitation (no rust and copper green), light weight (reduced 1/3), Shao Weixiu, long life (40 years service), life cycle cost (LCC) is low, Recyclable using green materials. According to reports, at present, Japan Tokyo area has reached 76% of the stainless steel pipe, pipe Water Leakage from the original 14.7% to the current 7.5%. Japan after the earthquake struck Osaka, stainless steel storage tank intact. Recently, Japan developed a corrugated pipe joint, the construction cost of stainless steel water pipe is reduced by 20%, 3% reduction in total cost, reduce the maintenance cost of 3/4.

Three, the construction industry

It is one of the earliest application field of stainless steel coil. In architectural decoration, at present, stainless steel is mainly used in coating, exterior wall of high-rise building interior and exterior columns, handrails, elevator floor, wall, doors and windows, curtain wall and other internal and external decoration and components. The stainless steel plate surface treatment, coloring, coating, to solve the problems such as easy to touch fingerprint, so the application range of the further expansion of stainless steel coil. Japan developed a variety of roofing materials such as stainless steel, corrosion resistance, high chromium ferritic and coating plate. Table UGITOP super-clean panel light brush surface plate, stainless steel coil Sweden developed France Ugine development, provides a new choice for the construction industry.

Four, household electrical appliance industry

In the home appliance industry, a large amount of stainless steel is the automatic washing machine drum, water heater, microwave oven, refrigerator inner shell inside and outside, and the use of ferritic stainless steel coil. Western European household electric stainless steel coil a larger proportion of Asia except Japan closer to the European level generally used less. In 1999, Japan's home appliance industry, the consumption of ferritic martensitic stainless steel coil austenite reached 28%, accounted for 12%. China's production of microwave oven, refrigerator, air conditioner, TV is competitive in the world exports, domestic appliance industry is a big potential market for stainless steel application. It is estimated that the next 5-10 years, stainless steel demand in China's household electrical appliance industry will reach 100 thousand tons of -15.

Five, environmental protection industry

Garbage and sewage treatment device of industrial waste gas, using stainless steel manufacturing. In the process of flue gas desulfurization, sulfur dioxide and chloride ions to resist corrosion, iron ion, in the absorption tower, cooler, pump, valve, etc. the flue need to adopt dual phase stainless steel and high grade austenitic stainless steel coil. It is required to use high performance stainless steel material waste incinerator, waste water treatment facilities.

Six, industrial facilities

In developed countries the proportion of industrial facilities, stainless steel coil can generally be used at present to 15%-20%, the domestic proportion is very small. This is because the industrial equipment imported stainless steel material, not statistics, on the other hand is due to the domestic material has not yet been adopted. The chemical, petrochemical, chemical, papermaking, food, medicine, energy (nuclear power, thermal power, fuel cell) and other areas in need of stainless steel coil. In addition, the existing imported equipment has entered the overhaul period. With the development of domestic stainless steel coil to improve the product quality and special product, the future application of domestic industrial facilities stainless steel coil will increase year by year.
