PM Stainless Steel Sintered Filters are porous filtration components manufactured through powder metallurgy technology using stainless steel powders.
Their controlled porosity provides excellent filtration efficiency, corrosion resistance, and mechanical strength.
Unlike conventional powder metallurgy structural parts that aim for high density, sintered filter discs are intentionally manufactured with controlled interconnected porosity to achieve efficient gas and liquid filtration performance.
Overview:
Powder Metallurgy is ideal for filter components requiring:
Controlled porosity
Corrosion resistance
High temperature resistance
Long service life
Unlike MIM, PM technology can intentionally maintain interconnected porosity, making it particularly suitable for filtration applications.
Filter Structure Types :
1. Sintered Metal Filter Disc
2. Sintered Stainless Steel Tube
3. Stainless Steel Cartridge Filter
4. Sintered Metal Filter Plate
5. Porous Metal Sheet
6. Cup Style Filter

Available Materials:
You can choose from many other metals and alloys to meet special filter requirements such as
higher temperature and pressure, corrosion resistance etc.
1.Stainless Steel; 316L, 304L, 310, 347 and 430
2.Sintered Bronze
3.Inconel® 600, 625 and 690
4.Sintered Nickel 200 and Monel® 400 (70 Ni-30 Cu)
5.Sintered Titanium
6.Sintered Alloys
