Zusammenfassung:	The invention discloses a thermal degreasing type binder, a feed, maraging stainless steel and a preparation method of the thermal degreasing type binder. The preparation method comprises the following steps that S1, powder mixing is carried out, specifically, Cu powder, Ni powder, Mo powder, Co powder and Fe powder are weighed and then mixed into metal powder; S2, mixing and granulation are conducted, specifically, the binder and the metal powder are subjected to mixing and granulation, and feed is obtained; S3, workpiece manufacturing is carried out, specifically, the feed is injected to obtain a green body; S4, degreasing and sintering are carried out, specifically, wherein the green body is sintered after being subjected to thermal degreasing; and S5, heat treatment is conducted, specifically, a sintered product is subjected to solution treatment and aging treatment, and the maraging stainless steel is obtained. According to the maraging stainless steel prepared through the preparation method, the ultimat
