UDDEHOLM HOTVAR
(Hot Work Tool Steel)

Hotvar® is a premium hot work steel developed by Uddeholm to provide very good performance in tooling up to 1200°F (650°C). The alloying elements in Hotvar® are balanced to give high hot wear resistance and good high temperature properties.
Manufactured by special techniques, Hotvar® is suitable for applications where hot wear and/or plastic deformation are the dominating failure mechanisms.



Applications and tools of special interest:
• Warm forging, dies and punches
• Roll forging, rolling segments
• Rock orbital forging, punches and dies
• Upset forging, clamping tools
• Progressive forging dies
• Axial closed die rolling, top and bottom dies
• Cross-forming segments
• Hot bending tools
• Hot calibration tools
• Zinc die casting dies
• Al-tube extrusion

Recommended hardness level is 54–58 HRC. For improving the wear resistance the tools can be plasma nitrided or nitrocarburized.
