Forging of High-Alloy Steel Ingots

Abstract

The forging of high-alloy 13Kh17N14M3 and 08Kh18N10T steel ingots (mass 5.3, 1.5, and 1.2 t) is considered. Five forging technologies based on microshear are considered: natural shear in forging by traditional tools, insertion hammers; and hybrid hammers; and applied shear in forging by hammers with working surfaces that cross in the transverse vertical plane. In forging with macroshear, the reduction is 1.78, while the total reduction in the ingot is 2.44. For all the forgings, the deformation of the metal is satisfactory, with no residual cast structure. The mechanical properties of the metal considerably exceed the standard requirements.
