Professional Hot Forged Bolts and Industrial Hot Forged Bolt Solutions
What is hot forged?
Hot forged is a metal processing method in which the metal is heated to a red-hot state to soften it, and then pressure is applied using a press to shape it. When the metal is heated above a certain temperature, it softens, and distorted crystals transform into normal crystals. This is called ‘recrystallization.’ Hot forging is carried out on metal heated above this ‘recrystallization temperature.’ This allows the metal to achieve high strength and high toughness.
Advantages of Hot Forged
1. Processing round bars into shapes close to the final product can reduce material costs.
2. Metal flow lines matching the product shape can be achieved.
3. The material structure is dense, with no internal defects.
4. Since the same mold is used, products with very small dimensional deviations can be produced.
5. High molding flexibility.
6. Capable of forging complex processes.
Disadvantages of Hot Forged
1.Due to thermal expansion and contraction, the processing accuracy is lower than that of cold heading, and additional machining is required to complete the part.
