Mold Steel
- Material Properties
- Sweden's special carburized plastic mold steel, cold extrusion molding plastic mold, in order to facilitate cold extrusion molding, this type of steel is in the annealed state It needs to have high plasticity and low deformation resistance. Therefore, this type of steel has low or ultra-low carbon content. In order to improve the wear resistance of the mold, this type of steel is generally carburized and carburized after cold extrusion. After quenching and tempering treatment, the surface hardness can reach
~
-.
- The cold extrusion molding method has the advantages of high production efficiency, high mold precision, and smooth surface. Some plastic molds with complex cavities can be made using this method. This type of steel has extremely low carbon content and has very low hardness after annealing. The hardness is
- when extruding complex cavities and the hardness is
- when extruding shallow cavities. This type of steel is added with alloying elements such as chromium that can improve hardenability but have little solid solution strengthening effect. The silicon content is low, the mold is carburized after cold extrusion, the surface hardness is
~
-, and the hardness after annealing is
~
-.
- Chemical composition
- The chemical composition (mass fraction) of the steel:
