Zusammenfassung:	The invention aims to provide a heat treatment method of novel martensitic stainless steel 2Cr14NiRE. The heat treatment method of the novel martensitic stainless steel 2Cr14NiRE specifically comprises the steps of conducting quenching, wherein the temperature of 920-980 DEG C is kept for 30-80 minutes, and then the martensitic stainless steel is oil cooled to the indoor temperature; and conducting tempering, wherein the temperature of 220-300 DEG C or 600-650 DEG C is kept for 50-80 minutes, and then oil cooling is conducted. The martensitic stainless steel 2Cr14NiRE treated by the adoption of the heat treatment method has a better mechanical property. 本发明的目的在于提供种新型马氏体不锈钢2Cr14NiRE的热处理方法，具体为，淬火：920～980℃保温30-80min后油冷至室温；回火：220～300℃或600～650℃保温50-80min空冷。采用该方法处理过的2Cr14NiRE不锈钢具有更好的力学性能。
