Stainless steel is widely used for its heat resistance in various applications. When stainless steel fibers are incorporated, additional properties such as conductivity and wave capture are introduced, enhancing its utility. The stainless-steel fiber needle mat stands out due to its exceptional dirt-holding capacity, precise filtration accuracy, gradual pressure increase, and extended replacement cycle, ensuring outstanding performance. It is resistant to corrosion from nitric acid, alkalis, and organic solvents, making it suitable for demanding environments. Moreover, it can withstand prolonged exposure to temperatures up to 700°C.
