Heat Treatment Alliance

Our business practice is to offer tooling solutions to the hot work industry with the goal of increasing productivity and optimizing tool life.

As a result of our experience in both the production and research of hot work die steels, Bohler-Uddeholm has been able to consistently improve material quality with regard to toughness, temper resistance, homogeneity and degree of purity.
These material improvements provide considerable advantages to both the toolmaker and end user, including the following:
- Resistance to heat checking
- Erosion resistance
- Increased hot strength

....and ultimately, longer tool life.

Die Casting
Pressure die casting offers an economical way of producing large quantities of complex, high-tolerance parts in aluminum, magnesium, zinc, and copper alloys. Demands placed on high-pressure die casting tool steels are increasing as the result of faster cycle times, high alloyed melts and more complicated product features. The ability to withstand thermal shocks and fatigue are the main properties the steel must display. Resistance to wear and corrosion are also important.

Hot extrusion of aluminum alloys, non-ferrous metals and steel involves the pressing of a hot billet through an aperture of a die to produce the required profile. The demands on the tool steel depend on the overall working temperature, i.e. on the metal being extruded, and on the location of the tool part in question. The component subjected to the most severe thermal influence and highest stress is, of course, the die. Other parts which experience high temperatures are the liner, dummy block and, in the cases where one is used, the mandrel.

Forging of steel, aluminum alloys and non-ferrous metals, mostly in the hot or warm condition, can be done on various types of hammers and presses, with open or closed dies depending on the size, weight, shape and quantity of the final part.
