Hot Forging

Hot forging is a manufacturing process used in the fastener industry to shape metal into various fasteners such as bolts, nuts, and screws. This process involves heating a metal billet or rod to a temperature where it becomes malleable, usually above its recrystallization temperature. The heated metal is then placed in a die and hammered or pressed into the desired shape.

Hot forging offers several benefits, including:

• Improved mechanical properties: The high temperature allows for better material flow, which refines the grain structure and enhances the strength and toughness of the fasteners.
• Complex shapes: It enables the production of complex shapes and designs that are difficult to achieve with cold forging or machining.
• Reduced stress and strain: The heating process reduces the resistance of the material, requiring less force to shape it, which minimizes stress and strain on the equipment.

This process is commonly used for high-strength fasteners that need to withstand heavy loads and harsh conditions, such as in construction, petrochemical and engine components.
