A302 the characteristics of cold extrusion of Grade A steel parts:

1,Save material
Cold extrusion parts material utilization usually can reach above 80%. Such as jiefang automobile piston pin machining material utilization was 43.3%, while in cold extrusion materials utilization rate increased to 92%; And as the universal joint bearing sleeve after using cold extrusion, material utilization ratio rose to 64% from 27.8% in the past. Visible, by adopting the method of cold extrusion production machinery parts, can save A lot of A302 Grade A steel and non-ferrous metal materials.

2,High production efficiency
Cold extrusion method to produce A302Gr.A mechanical parts has high  efficiency,especially in mass production.Cold extrusion method is more than several times than machining, even more than hundreds of times.

3,High strength
Cold extrusion methods to produce A302 Grade A material has strengthening characteristics. In other words, extrusion process of metal blank is in the state of three-way stress.When becomes deformation,the material changes density and continuous fiber flow.Therefore,A302GR.A material has high strength material.
