Introduction:

1.2550 Cold work steel with very good toughness, dimensionally stable, impact resistant, high hardening capacity. Similar with AISI S1.

Applications:

Typical applications include mandrel bars for drawing steel tubes, swaging, also punching, piercing, trimming dies and shear blades, forming and gripper dies.

HEAT TREATMENT:

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 RELIEVING:

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.
