Abstract: In accordance with defects of cracking, long processes, poor controllabiitiy, uneven structure properties during open-die forging processes for highMn-N alloy steel heavy retaining ring forging, a new saving force technology is developed by considering the practice. The punching-extruding, expanding-extruding complex hot forming of two punches with an outer ring is included in this technology. And the new technology is studied with both thermomechanical, numerical simulation, and test engineering design. Comphrehensive and systematic data of retaining ring forging are obtained. The technology is put into practice.

Key words: Heavy retaining rings, Hot forming, New technology
