The heat treatment method of die steel is closely related to the arrangement of processing procedures. During mold manufacturing, the heat treatment method shall be selected according to the material and processing process route, and the corresponding heat treatment process shall be formulated.

（1）一般冷作模具鋼工作零件的熱處理工序安排：籌造――退火――機械加工成型――淬火與回火―工修整。

(1) Heat treatment process arrangement of general cold working die steel working parts: preparation - annealing - machining forming - quenching and tempering - finishing.

（2）冷作模具鋼采用成型磨削及電加工工藝：鍛造――退火――機械粗加工――淬火或回火――精加工（磨削、電加工）。

(2) Cold working die steel adopts forming grinding and electric machining process: forging - annealing - mechanical rough machining - quenching or tempering - finish machining (grinding and electric machining).

（3）冷作模具鋼復雜沖模的加工：鍛造――退火――機械粗加工――高溫回火或調質――機械加工成型――淬火與回火――磨削與電工加工成型。

(3) Processing of complex die of cold working die steel: forging annealing mechanical rough machining high temperature tempering or quenching and tempering machining forming quenching and tempering grinding and electrical machining forming.

大多數冷作模具鋼使用狀態為淬火與回火，模具硬度通常為60hrc，為了進一步提高模具表面硬度、耐磨性和使用壽命，常進行表面強化處理，如滲碳、滲氮、滲硼氮碳共滲、td法滲釩鈮、化學氣相村積（cvd）等作為終熱處理。

Most cold working die steels are quenched and tempered, and the die hardness is usually 60HRC. In order to further improve the die surface hardness, wear resistance and service life, surface strengthening treatment is often carried out, such as carburizing, nitriding, boronizing, nitrocarburizing, TD vanadium and niobium, chemical vapor deposition (CVD) and so on.
