SS 316L Powder Sintered Filter Foam
SS316L powder sintered filter foam widely used in pneumatic components,chemical industry,environmental protection.
Product Introduction
Product Description
Sintered stainless steel porous materials are manufactured from metal powder through forming and high-temperature vacuum sintering, resulting in a rigid structure with uniform pore distribution.
These materials combine excellent mechanical strength, corrosion resistance, and precise filtration performance, making them ideal for demanding industrial filtration applications.
Manufacturing Process
Filtration of powder → Isostatic pressing → Vacuum sintering
This process ensures:
Uniform pore structure
High structural integrity
Stable filtration accuracy
