Typical Application: Typical hot work applications include mandrel bars for drawing steel tubes. Medium temperature applications include swaging, forming and gripper dies, also punching, piercing and trimming dies. Other applications include shear blades working at medium temperature including flying shear blades
Heat Treatment: Forge: at ********0°C and forge with light rapid blows. Reheat when temperature falls below **0°C if further work remains to be done. After forging, cool slowly, preferably in a furnace. Annealing: at**0?***0? Cool slowly in furnace Stress Relieving: Heat slowly to **0? and allow to cool in the air. Hardening: Preheat at **0? followed by rapid increase of temperature to ******0?. Quench in oil, tempering is always recommended after hardening.
