H13钢真空热处理质量优化工艺
摘要：
本发明公开了一种H13钢真空热处理质量优化工艺，包括加热保温、淬火、回火，所述的淬火工艺淬火采用的淬火介质为5～10％的盐水，处理件在淬火槽中冷却至室温，然后回火处理。本发明的工艺有效地提高了H13钢模具的淬火态硬度和冲击韧性；使得模具更加耐用，延长了使用寿命。具有可观的实用价值和经济价值。
摘要（英）：

The invention discloses a quality optimizing process for vacuum heat treatment of H13 steel, comprising the steps of: heating and heat preserving, quenching and tempering. In the quenching process, the quenching medium is 5-10% brine, and the processing part is cooled in a quenching tank to room temperature and tempered. The process can effectively improve the quenching hardness and impact ductility of a H13 steel mould, so that the mould is more durable, the service life is extended. The process has considerable practical value and economical value.
