Hot Work Tool Steel

    Hot work is one of the most challenging areas of manufacturing with demands on the die and tool steel always increasing. Most of the application areas share similar  problems of such as:
    • Hot wear
    • Thermal fatigue
    • Cracking
    • Plastic deformation
    Part manufactures are under pressure to reduce the cost of each part produced and here at Uddeholm we can help to optimize performance of your tooling with the correct choice of tool steel to best solve your problems.
