What is Warm Forging?
There are still several forging techniques exist for producing metal parts. And of course, each of them has specific advantages or disadvantages on certain condition. Considering everything from the steel alloy material to the shape, size, and quantity of the final product is important when determining which method will produce the best results at a lowest cost. The three forging methods are cold forging, warm forging and hot forging.
Here is the definition of warm forging: with warm forging, the workpiece heats to a temperature that exceeds the metal’s work hardening temperature yet remains low enough to prevent scale formation. This process leads to tighter dimensional tolerances than hot forging and increased workpiece ductility. Warm forging is defined as a process of plastically deforming a metal or an alloy such conditions of strain rate & temperature that the drawbacks of both cold working & hot working are greatly reduced & their advantages are combined together. However, warm forged parts are less ideal for more complex designs.
When working with hard metals such as steel, warm or hot forging techniques are generally preferable since cold forging increases the risk of cracking or breaking.
Warm forged parts become more and more popular during the last few years, especially as it leads to higher cost reductions by near net shape applications. Since warm forging has greater formability of heated materials, it also has greater accuracy.
The advantages accruing from warm forged parts are:
Reduced Energy Cost
Better Grain Structure
Better Surface Quality
Closer Tolerances
Marginal Machining Requirement
