First, the auto industry's fastest growing steel applications. In developed countries, automobile, bus, train, subway, high-speed rail transport vehicles, such as has been widely used in stainless steel. Body, exhaust system, fuel tank and other increasing use of stainless steel, stainless steel usage average Japanese car from 10-30 g, the United States has more than 40 kg. Second, storage, transportation, delivery, regeneration, stainless steel is widely used in water desalination and other industries. Japan developed as bellows, stainless steel pipes in road construction costs by 20% and total costs fell 3%, reduce maintenance costs 3/4. Third, the construction industry is one of the earliest areas of stainless steel, in architectural, structural steel roofing and building lots of stainless steel. Fourth, the environmental protection industry, industrial waste, garbage and sewage treatment plants made of stainless steel. Five, industrial facilities increasingly used stainless steel. Developed industrial facilities using generally 15% to 20% the proportion of steel, chemical, petrochemical, chemical, paper, food, medicine, energy (nuclear power, thermal power, fuel cells), and other areas that require stainless steel. Chromium is well known that one of the components of the steel, the corrosion resistance depends on imports of stainless steel chrome, protection methods vary. All metal and atmospheric oxygen are reacted in the surface oxide film is formed. Unfortunately, the iron oxide is formed on the plain carbon steel to continue the oxidation 316l stainless steel, so that corrosion of the stainless steel pipe expanding Wuxi, eventually the formation of holes. You can use paint or oxidation-resistant metal (eg, zinc, nickel and chromium) plating to ensure the carbon steel surface, but, as people know, this protection is only a film. If the protective layer is damaged, the following steel began to rust. When the addition amount of chromium 10.5% atmospheric corrosion resistance of steel significantly increases, but when the chromium content is higher, although still improving the corrosion resistance of 304 stainless steel tubes, but not significantly. The reason is that when using chrome steel alloying treatment, the type of change has become similar to the surface of the oxide surface oxides formed on pure chromium metal. Chromium-rich oxide protective surface such tight adhesion to prevent further oxidation. This oxide layer is very thin stainless steel tube, through which you can see the natural sheen of steel surface, so that the stainless steel has a unique surface. Moreover, if the surface is damaged, and atmospheric reactions exposed steel surface will self-repair, re-formation of this "passive film", continue to play a protective role. 316l stainless steel, high-quality stainless steel tube (certified), Stainless Steel Tube Co., Ltd.
