Hot forging die are usually made of materials such as H13 tool steel, which has high heat resistance, strength and toughness. Other materials such as D2 tool steel and high-speed steel can also be used for hot forging dies. These materials were chosen for their ability to withstand the high temperatures and mechanical forces experienced during hot forging. cold heading dies
Some disadvantages of hot forging include: Thermal Stress: Hot forging creates thermal stress in the workpiece which, if not managed properly, can lead to internal defects and dimensional inaccuracies. Oxidation: The high temperatures in hot forging can cause the workpiece material to oxidize, affecting its surface quality and performance. Energy consumption: Hot forging requires significant energy input to heat the workpiece to the required temperature, which results in higher operating costs. Tool wear: The high temperatures and mechanical forces in tungsten carbide hot forging die can cause accelerated wear of forging dies and tools, requiring frequent heading die maintenance and replacement. Limited material suitability: Not all materials are suitable for hot forging as some may degrade or oxidize at high temperatures, limiting the range of materials that can be effectively processed using this method. Longer processing time: Hot forging may require longer processing time compared to cold forging because the workpiece needs to be heated to the required temperature before forging. It is worth noting that while hot forging has these disadvantages, it also has unique advantages, tungsten carbide die such as improved material flow, reduced material strain hardening, and enhanced formability of certain materials.
