Heat Treatment:
Forging: Heat the steel carefully to a temperature of 1000-1050°C and forge with light rapid blows. Reheat when temperature falls below 900°C if further work remains to be done. After forging, cool slowly, ideally in a furnace.
Annealing: Heat the component slowly and uniformly to 800-810°C. Soak thoroughly for two to three hours and cool slowly in the furnace.
Stress reliving: If the machining operations have been severe, we recommend stabilising just before the tool components are finish machined to relieve machining strains. Heat slowly to a temparature of 700°C, allow to cool in air.
Hardening: Preheat at 650°C followed by rapid increase of temperature to 900-950°C. Quench in oil. Tempering of this grade is always recommended after hardening.
Tempering: Heat slowly to the required tempering temperature, soak thoroughly for two hours per 25mm section and allow to cool in air. For hot work applications, a minimum tempering temperature of 550°C should be used.
Applications:
Typical applications include mandrel bars for drawing steel tubes, swaging, also punching, piercing, trimming dies and shear blades, forming and gripper dies.
Introduction:
1.2550 Cold work steel with very good toughness, dimensionally stable, impact resistant, high hardening capacity. Similar with AISI S1.
