Hot Forging
The process of deforming the metal in an iron or special production forging die by applying pressure or impact is called forging. Forging is very important for shaping metal parts. Metal parts have good mechanical properties, allowing them to meet the requirements of use. When the temperature of the metal in the forging process is above the recrystallization temperature, it is called hot forging.
Hot Forging Process
Hot forging is a metalworking process in which the metal is deformed by exceeding its recrystallization temperature and allows the part to maintain the desired shape as it cools. Hot forging is carried out at the highest temperature value that will not destroy the metallurgical properties of the alloy to be obtained. These values are; 1250°C for steel, 750-1040°C for titanium alloys, 300-460°C for Al-Alloys and 700- 800°C for CU alloys. In some cases, excessive strokes are applied by repositioning the products in the mold for the final volume and size desired to be delivered.
Hot Forging Advantages
Hot forging has many advantages over cold forging. These can be listed as follows:
Providing correct shaping,
Ability to easily obtain even complex shapes,
Ensuring the removal of chemical impurities,
High fracture resistance,
A smooth surface can be obtained after application with homogenized grain structure,
Easy processing of parts with higher volume and weight,
Improved, it prevents the carrying capacity from changing even after the process.
