个人中心收藏查看我的收藏0有用+10播报讨论上传视频马氏体型耐热钢，适用于高温部件制造是以马氏体组织为主的耐热钢材料 [1] [3]，其标准执行GB/T 1221-1992，适用于工作温度不超过540℃的汽轮机叶片等高温环境部件 [1] [3]。该材料具有优异的力学性能，抗拉强度≥685MPa，冲击功≥78J，通过淬火及回火工艺可获得217～248HB的硬度 [1] [3]。产品形态包含棒材、锻件与钢管等多种类型 [1-2] [4]，可提供深加工与表面酸洗处理服务 [4]。标    准GB/T 1221-1992 [1]
适用温度≤540℃ [1]
产品形态棒材/锻件/钢管 [1]
密    度7.75g/cm³ [3]
交货状态热处理或未处理 [1]
产    地国产 [4]

目录
1材料特性2化学成分与性能3热处理工艺4应用领域5生产与加工
材料特性
播报编辑在淬火状态下兼具高硬度与耐蚀性，通过调整铬（11.50～13.00%）和钼（0.30～0.60%）含量提升耐热性 [1] [3]。其金相组织为典型马氏体形态 [3]，常规使用需配合回火工艺以稳定性能 [1]。
化学成分与性能
播报编辑元素配比：碳0.10～0.15%、硅≤0.50%、锰0.30～0.50%、铬11.50～13.00%、钼0.30～0.60%、硫≤0.030%、磷≤0.035%、镍0.30～0.60%、铜允许含有≤0.30% [1] [3]力学指标 [1] [3]：抗拉强度≥685MPa，伸长率≥18%，断面收缩率≥60%，硬度（淬火回火）217～248HB
热处理工艺
播报编辑1.退火：800～900℃缓冷或750℃快冷 [1]2.淬火：950～1000℃油冷，推荐1000℃加热以平衡组织与硬度 [3]3.回火：700～750℃快冷 [1]
应用领域
播报编辑主要应用于汽轮机叶片制造 [1] [3]，同时拓展至机械制造、压力容器、轨道交通、汽车用、太阳能、金属制品、家用电器、电子、集装箱、电梯、卫生洁具、建筑装饰、核电、餐饮厨具、化工设备、日用电器、食用机械、结构制管等领域。其半成品可通过冲压、折弯等加工方式适配不同工业需求 [4]。
生产与加工
播报编辑材料支持定制化加工服务，包括开平、分条等粗加工及冲压成型等深加工。成品表面经酸洗处理，可根据需求调整交货状态。截至2025年，宝钢不锈等企业为国内主要生产商之一 [4]。的图片(1张)新手上路成长任务编辑入门编辑规则本人编辑我有疑问内容质疑在线客服官方贴吧意见反馈投诉建议举报不良信息未通过词条申诉投诉侵权信息封禁查询与解封©2025 Baidu 使用百度前必读 | 百科协议 | 隐私政策 | 百度百科合作平台 | 京ICP证030173号 京公网安备11000002000001号window.PAGE_DATA=
