The difference between stainless steel and stainless iron stainless steel decoration industry at the moment than force disturbance, filled with some fake stainless steel tube in the decoration industry, impact on the stainless steel decoration engineering industry, here are small make up some "imitation stainless steel tube way for master study Stainless steel decoration pipe generally is the floorboard of the steel tube and acid-resistant steel stainless steel decoration. Stainless steel refers to the resistance to gas, steam and water and other weak medium erosion of steel, and acid steel refers to the resistance to acid, alkali, salt and other chemical corrosion medium erosion of steel. The discovery of stainless steel is a major achievement in the history of the world metallurgy, the growth of stainless steel for the growth of modern industry and scientific and technological progress laid the foundation of the main material technology. Stainless steel decorative steel pipes are generally used in the case of anti-erosion, as well as medical devices and articles for living. So-called "stainless iron", is to take over the old iron, lead, steel and other through second oven processing, through the process to take off the "zi" disposal, traditional way of testing is to use magnets, and this item is unable to distinguish with traditional way, natural is stolen, covering the pile of engineering material, the emperor is hall place another decoration site, entered a boarded a picture of another Luxurious curtain wall. This name is born after "core interview" exposure, and occupy about 65% of the market share, and the real NATIONAL standard SUS304 stainless steel products because of higher prices and no market. Current market "stainless iron" products can have 65% of the share is the price of the main effect, now the national standard stainless steel product price of about 20,000 yuan per ton, national standard 7075 aluminum alloy price is about 16,000 yuan per ton, and the price of "stainless iron" per ton is only 5000-7000 yuan; Then look at the tensile strength of these three materials: gb stainless steel 530-620
