Forged steel is a steel alloy that is compressed under extreme pressure to make a very hard and strong substance. This type of material has been widely used in forging process since the origin of forging technique. Modern forged steel is conducted using specialized machines or hydraulic hammers.
Compared with cast steel, forged steel parts can ontain high strength and better toughness. When producing forged steel parts, the metal can either be kept at room temperature (cold forging) or heated to high temperatures (hot forging), refer to hot forging vs cold forging for the differences. The higher the temperature, the easier it is for the metal to take shape and less likely to crack.
Closed die forging is the forging technique widely performed for forged steel parts. During closed die forging process, the upper and lower dies are separated into two halves and they move towards each other completely covering the forged steel workpiece. Then the forged steel billet is heated above the recrystallization temperature and placed in the bottom die. The impact or the external force is applied from the above, which forges the material into required shape. Though the initial setup cost for the closed die forging is higher than other processes, but still, it is extensively used because the production cost is very low as compared to the other processes and the forged material gets 20% higher strength to weight ratio than the other processes.
Advantages of Closed Die Forging for Forged Steel Parts
- Has an increased grain flow
- Very high in strength and tightness
- It is a very cost effective process considering the low production cost
- Suitable for all kinds of materials like steel, brass and aluminium
- Has a better surface finish thus very low machining is required
- Highly eco-friendly process
To produce the forged precision steel parts needed, forging companies usually make use of closed die forging. The closed die forgings are done because it gives the metal high strength and toughness though the initial setup cost is high.
