Product Introduction sintered porous stainless steel filter is a type of filter made from stainless steel powder that has been sintered, or fused together, to form a porous structure. Sintering involves heating the stainless steel powder to a high temperature, just below its melting point, to fuse the particles together without completely melting them. The pore size and distribution of sintered porous stainless steel filters can be controlled during manufacturing. This enables filters to be tailored for specific applications, such as filtering out large particles or removing smaller contaminants. Sintered porous stainless steel filters are made from high-quality stainless steel powder that is sintered together to create a strong and durable material. They can withstand high pressures, high temperatures, and harsh chemical environments. Parameters
