Uddeholms AB is a multinational producer of high alloyed tool steel with production in Hagfors, Sweden.

[citation needed] The company was introduced to the United States in the 1830s and in the 1920s a modern international sales organization was created.

After melting, the steel is purified in a secondary treatment to remove sulfur, slag and other unwanted materials.

With this process, a more even microstructure can be achieved which gives completely different properties than a material produced with the conventional method.

The advantage with powder metallurgical tool steels is to have a high degree of alloys without getting segregations in the material.

In the GRANSHOT process, hot liquid molten metal is poured at a flat surface, dispersing it so that small droplets are created.

In 2007, the independent and privately owned Swedish engineering company UHT - Uvån Hagfors Teknologi AB, was formed and also took over all intellectual property rights including the trademark GRANSHOT.

Uddeholms AB manufacture and refine high alloyed tool steels in long and flat dimensions.

Tool steels are used in all manufacturing industries such as automotive, electronics, consumer goods and packaging.

Common problems are wear, chipping, plastic deformation and cracking which can lead to tool failure.
