What are the materials of shredder blades?

There are two types of shredder blades, including multi axis blades and single axis blades. Let's first look at the materials of single axis shredder blades. The materials of single axis shredder blades are relatively single, including 9CrSi and Cr12MoV. Compared with 9CrSi, Cr12MoV single axis shredder blades have better performance than other materials. There are many materials for multi axis shredder blades, including tool steel and die steel. Let's take a look at the differences between the two materials. Tool steel is commonly used in plastic tearing and wood tearing, and the price is relatively cheap. However, it has good toughness and good impact resistance. The commonly used materials of this tool steel are 9 CRSI and 6crw2s. Mold steel is better than tool steel because of its good hardenability and wear resistance. It is used to produce high-quality shredder blades. The common materials are SKD11, D2, Cr12MoV, etc.
