Nowadays, there are mainly 201 and 301 stainless steel decorative tubes on the market. The difference is mainly caused by the difference of chromium, nickel and other components. Material 304 contains Cr18 and nickel 8-9, while material 201.301 contains only Cr 14-16 and Nickel 0.8-1.0. Through scientific analysis and demonstration, the better the performance index of stainless steel tube with high content of C and nickel and good smelting level, the stronger the corrosion resistance level and the stronger the finish
