We all know that the cutter of a scrap metal shredder determines the thickness and hardness of the material that can be shredded. The cutter of the shredder is the most important part of the shredder, and its service life directly affects the performance of the shredder.
The shredder tool materials are often made of cold work die steel and hot work die steel. Commonly used steel grades: D2 (Cr12Mo1V1), DC53 (Cr8Mo2SiV), H13 (4Cr5MoSiV1), SKD11 (Cr12MoV), etc.
Due to the excellent wear resistance and hardenability of die steel raw materials, the shredder blades produced follow the high-precision route. Commonly used are DC53, D2, SKD11, Cr12MoV, etc. However, tool steel is relatively cheap and has better resistance and impact resistance. It is still very useful for shredding of some conventional plastic shredding and wood shredding. Commonly used raw materials are 6CrW2Si and 9CrSi.
The selection of raw materials for shredder blades is like building a house. A foundation is laid. If the foundation is strong, the house will naturally be more reliable. If the shredder tool materials are selected, the processing of the materials will be simpler in the future, and the unit output and power will be increased, which will provide more guarantee and development for the development of the recycling industry.
