In this paper, the maraging steel contg. dispersed carbide is sintered and then the body is heated to 650 to 800 deg.C to soften it before the solution heat treatment.Abstract:
PURPOSE:To improve machinablity of the maraging steel contg. dispersed carbide. CONSTITUTION:The maraging steel contg. dispersed carbide is sintered and thereafter the sintered body is heated to 650 to 800 deg.C to soften it before the solution heat treatment. With this softening step, the hardness of the sintered body can be lowered to a value sufficient for performing the machining without adversely affecting the other characteristics. Thereafter the resulting sintered body is subjected to solution heat treatment and age hardening treatment. Thus the maraging steel which contains dispersed carbide and has excellent hardness and superior wear resistance can be produced.read more
