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.
