4. Heat treatment Related

• Annealing of 1- Tool steel

At first, Slowly heated to 750-780 &#; and allow enough times, let the steel to be thoroughly heat, Then cool slowly in the furnace. Then the tool  steel will get MAX 250 HB &#;Brinell hardness&#;.

• Hardening of 1- tool steel

1. steels should be heated uniformly to -°C. until completely heated through. And if needed, the steels can be preheated at 300-500°C (572-932°F). About 30 min per 25 mm of ruling section is to be provide and then the steels should be immediately quenche in oil or air.

• Tempering of 1. tool steel

At first, tempering of 1. steels is performed at 550-650°C, Soak well at the selected temperature and soak for at least one hour per 25mm of total thickness. Then get Rockwell C hardness of 56 to 38.

Temperature [&#;]       400   500     550     650

Hardness [HRc]          53      56        54       47

5. Mechanical Properties

The mechanical properties of 1. tool steels are outlined in the following table.

Tensile strength, ultimate (@20°C/68°F, varies with heat treatment) Tensile strength, ultimate (@20°C/68°F, varies with heat treatment) Reduction of area (@20°C/68°F) Modulus of elasticity (@20°C/68°F) Poisson&#;s ratio MPa MPa Gpa - - 50% 215 0.27-0.30

6. Applications

And 1. steels are mainly used for forming extrusion dies.Typical applications include casting molds aluminum, magnesium, zinc, copper and aluminum extrusion dies, liners, spindles, pressure pad, followers, pad, die, the death and the adapter ring copper and brass extrusion.

Moreover, 1. is used to produce hot stamping and extrusion die forging, thermal upsetting dies, jigs mold, hot embossing, punching, trimming tools. Other applications include plastic molds, shear blades for heat and hot extrusion dies.
