Our company integrates the production and development of special alloys, high-temperature alloys, precision alloys and other high-tech enterprises. The company's products have excellent performance and diverse specifications. We sincerely welcome customers to visit and negotiate. The following are the forging requirements of special alloys, you may wish to find out.
First of all, due to the high degree of alloying of special alloys, severe macrosegregation of ingots and forgings, and low plasticity, it is easy to crack during forging. The deformation temperature, degree of deformation and deformation speed need to be strictly controlled, and try to avoid tensile stress. Deformation, and special alloys have poor fluidity and are difficult to fill the cavity. Compared with forgings of the same geometric size as general alloy structural steels, it is necessary to choose equipment with greater energy and live load for forging. In addition, because special alloys are sensitive to the strain rate and allow lower strain rates than ordinary steels, it is necessary to choose forging equipment with a slow working speed and a low speed for forging, so that the choice of equipment is reduced, and some special plastic stress states are sensitive. In order to prevent forging cracks, it is necessary to perform forging in a compressive stress state such as pressing and closing a forging die.
