Products Description

High Strengthen Flat Round Head Bolt With 6 Holes Screw With Full Thread. Increasing the temperature can improve the plasticity of the metal and make it difficult to crack. High temperature can also reduce the deformation resistance of metal and reduce the tonnage of forging machinery required. High temperature deformation is beneficial to improve the internal quality of the workpiece. However, there are many hot forging processes, the precision of the workpiece is poor, the surface is not smooth, and the forging is prone to oxidation, decarburization and burning. When the metal (such as lead, tin, zinc, copper, aluminum, etc.) has enough plasticity and the amount of deformation is not large (such as in most stamping processes), or the total amount of deformation is large and the forging process used (such as extrusion, Radial forging, etc.) is conducive to the plastic deformation of metals, often not using hot forging, but instead using cold forging. In order to complete as much forging work as possible with one heating, the temperature range between the initial forging temperature and the final forging temperature of hot forging should be as large as possible. However, if the initial forging temperature is too high, it will cause the metal grains to grow too large and form overheating, which will reduce the quality of the forging. When the temperature is close to the melting point of the metal, the melting of the low melting point substance between the crystals and the oxidation between the crystals will occur, resulting in overburning. The burnt blanks tend to crack during forging. The commonly used hot forging temperature is: carbon steel 800～1250℃; alloy structural steel 850～1150℃; high speed steel 900～1100℃; commonly used aluminum alloy 380～500℃; titanium alloy 850～1000℃; brass 700 ～900℃
