摘　　要：高温均质化、超细化处理是优质H13模块生产中的关键热处理技术。高温均质化处理可基本消除钢中的共晶碳化物,显著改善成分偏析;超细化处理可使H13组织得到细化,进一步提高性能均匀性。五钢新流程生产的P级H13(SWPH13)等向性明显改善,冲击韧性、热疲劳抗力显著提高。Both high temperature homogenization treatment and superfining treatment are key Heat treatment techniques in the production of quality H13 die steel block. High temperature homogenization treatment can basically eliminate eutectic carbide and dramatically improve the segregation in steel. Superfining treatment can further improve its uniformity of both microstructure and performance. Die steel Grade P H13 (SWPH13) produced in the new process flow route in Shanghai No.5 Steel has been well-improved in anisotropy, impact toughness and thermal fatigue resistance.
