Nitride hardness: HRC59 ° -65 °
The function of screw barrels in injection molding machines made of other nitriding materials is to:
1. Nitriding can increase the surface hardness and wear resistance of screw barrels. For example, screw barrels made of high-quality alloy steel 38CrMoAlA can have a surface hardness of HV950 or above after nitriding treatment, equivalent to HRC=55 ° -58 °. Moreover, the high strength and wear resistance after nitriding are maintained at 350-450 ° C without significant changes
2. It can improve fatigue resistance. Due to the formation of greater compressive stress within the nitride layer, the screw barrel exhibits higher fatigue limit and lower notch sensitivity under alternating loads. After nitriding, the fatigue limit of the screw barrel can be increased by 30%
