Shredder Blades are typically made from a selection of materials, including 9CRSI, CR12MOV, and SKD-11.

9CRSI is an alloy tool steel characterized by its high hardness but also its brittleness. This material is particularly well-suited for Shredding soft waste materials such as rubber, fiber, and paper. The high hardness of 9CRSI ensures effective cutting and shredding of these materials.

CR12MOV and SKD-11, both cold working die steels, exhibit similar properties. These materials are specifically designed to handle the tearing and shredding of harder substances like wood, waste household appliances, and plastics with high hardness. Blades made from CR12MOV and SKD-11 offer exceptional toughness and durability, enabling them to withstand the demanding tasks associated with shredding these tough materials.
