Uddeholms AB is a multinational producer of high alloyed tool steel with production in Hagfors, Sweden. Since 1991, the company is part of the Austrian Böhler-Uddeholm group which in turn is part of the voestalpine AG group since 2007. Uddeholms AB has 800 employees in Sweden. Globally, the Uddeholm group employs 3000 people.

Products

Uddeholms AB manufacture and refine high alloyed tool steels in long and flat dimensions. Tool steels are mainly used in tools such as molds, knives, tools that are used for manufacturing of different products. Tool steels are used in all manufacturing industries such as automotive, electronics, consumer goods and packaging. Due to their special metallurgical properties, e.g.combinations of hardness, wear resistance, toughness, corrosion resistance, they can also be used for mechanical applications instead of engineering steels.

Cold Work Steels

Cold Work Steels are tool steels used for tools where the work material is cold. The steel is exposed to mechanical forces by the work material. Common problems are wear, chipping, plastic deformation and cracking which can lead to tool failure. Application areas are stamping, deep drawing, cold extrusion, fine blanking, cold forging, form pressing and rolling.

Hot Work Steels

Hot Work Steels are tool steels that are used for tools where the material is hot. Due to the high temperatures when working with molten metals such as aluminium, iron and brass, the requirements on the tools are very high. High heat resistance and ductility as well as wear resistance are important. Resistance to thermal cyclic stress is also good. Application areas are casting, extrusion and forging.

Plastic Mold Steel

Plastic Mold Steels are tool steels used for production of plastic parts. The most important characteristics are durability and hardness, toughness, wear resistance, polishability, corrosion resistance, and thermal heat conductivity. Important customer groups are in the automotive, consumer goods industry, electronics and other industries that use plastic components. Application areas are blow molding, form pressing, form blowing, extrusion and holder materials.

Mechanical components/Mechanical engineering

Mechanical components such as engine parts (shafts cog wheels), machine parts, wear parts can be made of tool steel. The combinations of hardness, toughness, corrosion resistance and other properties of tool steels, makes it possible to replace more traditional engineering steels.
