The difference between stainless steel and stainless steel At present, the stainless steel decoration industry is full of chaos, and some fake stainless steel pipes are flooded in the decoration industry, which has a huge impact on the stainless steel decoration engineering industry. The following introduces several methods for identifying imitation stainless steel pipes. Stainless steel decorative pipes are generally called stainless steel decorative pipes and acid-resistant steels. Stainless steel refers to steel that is resistant to weak media such as gas, steam, and water, while acid-resistant steel refers to steel that is resistant to chemically corrosive media such as acid, alkali, and salt. The discovery of stainless steel is a major achievement in the history of world metallurgy. The development of stainless steel has laid the foundation for the development of modern industry. With the progress of science and technology, stainless steel decorative steel pipes are generally used for anticorrosion, medical equipment and daily necessities. The so-called "stainless steel" means that the received and received scrap iron, lead, steel, etc. are processed in the secondary furnace, and then dezincified; The traditional detection method is iron absorbing stone, which cannot be distinguished by traditional methods. Naturally, it shelters the sky and hides a large amount of engineering materials. It is the land of Yitang Baihuang. They enter the decoration site one by one and board one luxury curtain wall one after another. This name was born after the exposure of "Core Interview", and it occupies about 65% of the market share. At present, the price of national standard SUS304 stainless steel products is about 20,000 yuan / ton, the price of 7075 aluminum alloy is about 16,000 yuan, and the price of stainless steel is "; each The ton is only 5000-7000 yuan. The tensile strength of the three materials is: stainless steel 530-620mpa, 7075 aluminum alloy 540-560mpa, stainless steel 160-180mpa. Obviously, the tensile strength of stainless steel is less than 1/3 of stainless steel. Therefore, In the construction industry, we should firmly ban stainless steel finished products.
