《GB/T 22561-2008真空热处理》由TC75(全国热处理标准化技术委员会)归口,主管部门为国家标准化管理委员会。
本标准修改采用SAE AMS 2769A:2004《零件的真空热处理》(英文版),本标准根据SAE AMS 2769A:2004重新起草。
本标准规定了金属材料在真空状态下热处理的设备、工艺材料、热处理工艺及技术要求、品质控制及检验、能源消耗、安全卫生及要求等。
本标准适用于结构钢、工具钢、模具钢、不锈钢、耐热钢、钛合金、高温合金、难熔金属合金、精密合金等金属材料的真空热处理、包括真空加热淬火、真空回火、真空退火、真空固溶处理、真空时效等工艺。
本标准不适用于真空渗碳或真空渗氮等工艺。
本标准与SAE AMS 2769A:2004相比,存在如下技术性差异:
――本标准的标准名称、规范性引用文件、工艺分类及代号和常用材料牌号与SAE AMS 2769A:2004不同;
――本标准修改SAE AMS 2769A:2004中的非标准计量单位为标准计量单位;
――本标准删减了SAE AMS 2769A:2004中的第8章内容,用“术语和定义”替代部分内容;
――本标准增加了真空热处理工艺内容;
――本标准增加了安全卫生、环保及能源消耗要求。
