In the manufacturing process of tungsten steel saw blades, powder metallurgy is one of the core steps. Its core steps include the following:
- Powder preparation: Tungsten, steel and other alloying elements are prepared into powders through chemical or physical methods.
- Press molding: Put the powder into the mold and apply pressure to turn it into a blank with a certain shape and density.
- Sintering: heating the blank to a certain temperature to cause physical and chemical changes to increase its density and strength.
- Follow-up processing: The sintered tungsten steel material is cooled, ground, cut, etc. to obtain tungsten steel saw blades of the required shape and size.
In the powder metallurgy process, each step has strict requirements and controls to ensure the quality and performance of the final product. At the same time, tungsten steel materials prepared by powder metallurgy have the advantages of high density, high strength, high hardness, and good wear resistance and corrosion resistance, and are suitable for manufacturing high-hardness cutting tools such as tungsten steel saw blades.
