Stainless steel filter bags are generally used to filter rust. Because rust is a highly corrosive substance, and stainless steel material has corrosion resistance, which can effectively prevent filter bags from being corroded and damaged by rust. In addition, stainless steel filter bags also have advantages such as high temperature resistance, wear resistance, and easy cleaning, making them suitable for rust filtration in various complex working conditions and environments. Of course, the selection of filter bag material also needs to be comprehensively considered based on specific factors such as rust particle size, shape, density, etc.
