UH1 Steel

UH1 Steel

Steel name: UH1
Diagram No.: 2479
Chemical composition in weight %: 0.46% C, 0.45% Si, 0.50% Mn, 6.70% Cr, 1.50% Mo, 0.80% V
Steel group: Hot work tool steels
Properties: A premium tool steel for high wear resistance to increase tool performance. UH1 is a Cr-Mo-V alloyed premium steel with a special manufacturing process to ensure excellent wear resistance combined with high toughness. With the development of the steel UH1, we are meeting market demands for higher wear resistance of tools in modern hot stamping processes. UH1 minimizes tool wear and extends tool performance. UH1 is a premium steel for tools with the highest performance potential.
Applications: No data
Reference: Not shown in this demo version.

Heat Treatment
Hardening: The recommended austenitizing temperature is 1050 °C for a soaking time of 45 min. Depending on cross-section and required hardness, quenching is carried out by blowing in nitrogen at an overpressure between 4.5 and 10 bar. For large cross-sections, a warm bath quenching simulation is also possible.
Tempering: The first tempering should be carried out immediately after quenching. Tempering is preferably performed in a vacuum furnace or in an inert gas furnace. The first tempering temperature depends on the required hardness (see tempering diagram). The selection of the second tempering temperature depends on the hardness achieved after the first tempering.
