Nickel is the eighth group of metal chemical elements in the periodic table of Melev element, which is a member of Fe, Co and Ni iron group. It is a yellowish silver-white malleable metal, is a magnetic transition metal, density of 8.9 grams per cubic centimeter, melting point 1455 degrees, in the air nickel surface can form a Nio film, can prevent oxidation. Experiments show that nickel with a purity of 99% will not rust in 20 years. Nickel has strong corrosion resistance, especially to caustic soda. The corrosion rate of nickel in 50% boiling caustic soda solution is no more than 25 microns per year. According to the national standard, the nickel content of 304 stainless steel is 8%, the nickel content of 316 stainless steel is 10%, and the nickel content of 316L is 12%. The raw materials of stainless steel imported by our company are all in accordance with the national standard. Therefore, the nickel content of stainless steel mesh produced by our company is sufficient, and the stainless steel mesh produced by our company has strong ability to prevent oxidation
