The sintered metal fiber felt is formed by non-woven laying, stacking, and high-temperature sintering of micron-level metal fibers. The multilayer metal fiber felt creates a pore gradient through layers of different pore sizes, enabling extremely high filtration precision and a larger dirt-holding capacity than single-layer felts. It maintains continuous filtration performance with characteristics such as a three-dimensional network structure, high porosity, large surface area, and uniform pore size distribution, exhibiting excellent structural properties.

Therefore, the sintered metal fiber felt effectively overcomes the defects of metal meshes being prone to clogging and damage, of powder filtration products being fragile and having low flow rates, and solves the issues of filter paper and cloth not resisting high temperatures or pressure.As a result, stainless steel sintered felt has excellent filtration performance and serves as an ideal filter material with high-temperature resistance, corrosion resistance, and high precision.
