Spheroidizing Annealing is one of Basic Ways of improving structure of steel and performance, the main purpose of Spheroidizing Annealing is the carbide spheroidization that makes in the microtexture of ferrous materials, reduces the hardness of material, improves the plasticity of material, reduce the resistance to deformation of material, make material be easy to plastic working and be shaped.Will obtain ideal performance and tissue in the screw wire production, key is to select suitable carbide annealing process.
