加工性能
播报编辑支持锻造、轧制、机械切削等工艺，焊接时需配合固溶处理以消除热影响区敏化风险。冷加工硬化率较低，适合深冲压成型。
国际标准对应
播报编辑中国：GB/T 1220-1992标准S30453/022Cr19Ni10N美国：ASTM A标准S30453日本：JIS SUS304LN德国：DIN 17400标准1.4311欧盟：EN标准X2CrNiN18-10
质量检测
播报编辑硬度检测采用光谱分析仪、原子吸收光谱及色度元素分析仪，其中光谱分析仪精度最高，可快速测定成分偏差。晶间腐蚀测试依据GB/T 4334标准执行。
市场流通
播报编辑该合金在中国长三角、珠三角地区（如上海松江区、东莞市）形成稳定供应链，由多家金属材料企业实现规模化生产与销售 [1]。产品形态涵盖棒材、板材、管材及定制加工件，满足工业领域多样化需求。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= {"lemmaId":5207142,"lemmaTitle":"","lemmaDesc":"低碳高氮奥氏体不锈钢","lemmaType":0,"uid":126255139,"uname":"cyy72810","createTime":1306825107,"updateTime":1750651663,"isDefault":0,"isDeleted":0,"rank":1,"extData":{"discussion":{"relateInfo":[{"relateId":33085,"relateType":1},{"relateId":32990,"relateType":1}]},"isBaikeV6":1,"isFrontV6":1,"isSapp":0,"isWaitForPersonal":false,"kpdClassify":[{"id":337502,"name":"工业产品"}],"lemmaId":5839450,"lemma_id":5839450,"newEditor":1,"pass_count":11,"subLemmaId":5898425,"updateTime":1750651664,"wapEdit":0},"extFlag":0,"versionId":650500125,"versionUid":6863166061,"versionUname":"孤独像素画","versionCreateTime":1750651660,"catalog":[{"level":1,"title":"化学成分","index":"1","uuid":"i2p4y4x2rb","height":28},{"level":1,"title":"物理性能","index":"2","uuid":"i2p4y4x5rg","height":28},{"level":1,"title":"力学性能","index":"3","uuid":"i2p4y4x7kc","height":28},{"level":1,"title":"热处理工艺","index":"4","uuid":"i2p4y4x8zp","height":28},{"level":1,"title":"应用领域","index":"5","uuid":"i2p4y4xac6","height":28},{"level":1,"title":"加工性能","index":"6","uuid":"i2p4y4xbsg","height":28},{"level":1,"title":"国际标准对应","index":"7","uuid":"i2p4y4xcr8","height":28},{"level":1,"title":"质量检测","index":"8","uuid":"i2p4y4xdvr","height":28},{"level":1,"title":"市场流通","index":"9","uuid":"i2p4y4xeye","height":28}],"abstract":[],"reference":[{"type":1,"title":"【供应厂家出售,批发,厂家直销图片】供应厂家出售,批发,厂家直销图片大全 - 上海益励金属材料有限公司","site":"中国供应商网","publishDate":"2025-05-24","index":1,"uuid":"i2p4y5bk72","encodeUrl":"533aYdO6cr3_z3kATPGOyPXyZHnHMNr4trPXAeBzzqIPmGapB43rFIs66dk-sPRpWxvCs9cwN4FHzr3zCk1NgfcOKaloHg"}],"modules":{"adManager":{"data":{"wapRelatedBusiness":1}},"discussion":{"showHelpEdit":1},"globalConfig":{"data":{"serviceAdLemmaCategory":[337597,337474]}},"paper":{"switch":false},"pinzhuan":{}},"card":{"type":243,"left":[{"key":"customDefault","title":"材料类型","isArray":false,"delimiter":"","data":[{"dataType":"text","text":[{"tag":"text","text":"奥氏体不锈钢"}]}]},{"key":"customDefault","title":"密度","isArray":false,"delimiter":"","data":[{"dataType":"text","text":[{"tag":"text","text":"7.93kg/dm³（20℃）"}]}]},{"key":"customDefault","title":"抗拉强度","isArray":false,"delimiter":"","data":[{"dataType":"text","text":[{"tag":"text","text":"≥550MPa"}]}]}],"right":[{"key":"customDefault","title":"屈服强度","isArray":false,"delimiter":"","data":[{"dataType":"text","text":[{"tag":"text","text":"≥245MPa"}]}]},{"key":"customDefault","title":"伸长率","isArray":false,"delimiter":"","data":[{"dataType":"text","text":[{"tag":"text","text":"≥40%"}]}]},{"key":"customDefault","title":"硬度","isArray":false,"delimiter":"","data":[{"dataType":"text","text":[{"tag":"text","text":"≤217HBW"}]}]}]},"lemmaCnt":1,"tips":{"isPolyseme":0},"encodeLemmaId":"db3f0c119cf229d5057ca7d1","versionUk":"uSstM1L7G43tNzP_u7Tz6w","description":"是在00Cr19Ni10基础上添加氮元素改良而成的奥氏体不锈钢，其碳含量≤0.030%，铬镍含量分别为17.00-19.00%与8.50-..."}window.__abbaidu_2020_subidgetf||(window.__abbaidu_2020_subidgetf=function(){return"01000000"}) 00Cr18Ni10N 00Cr18Ni10N属于奥氏体类型的不锈钢，与304L钢相比，添加了N，以提高结构件用高强度性及耐粒界腐蚀性。主要用做结构钢使用，如化学物质运输船。 00Cr18Ni10N不锈钢在304N的基础上降低了碳含量，因304N在450~900度加热后耐晶间腐蚀性能明显下降，因此对于焊接设备结构件，推荐用本材料。 00Cr18Ni10N应用和特性：00Cr18Ni10N应用领域：用于有一定耐蚀性要求，并要求较高强度和减轻重量的设备和结构部件。特别是焊接设备结构件，推荐用本材料。 PRODUCT PARAMETERS 产品参数 化学成分 成分 C Si Mn P S Ni Cr N 最小值 - - - - - 8 18 0.1 最大值 0.03 1 2 0.045 0.03 11 20 0.16 物理性能 密度g/cm 比热容/kg/(kg.k)℃100~900℃ 热导率/w/(m.k)100~500℃ 线胀系数/(10-6/k)20℃ 电阻率/（Ω.mm2/m)20℃ 纵向弹性模量/GPa 硬度HRB 磁性 ≤95 无 16.3-21.5 16.5~18.5 0.72 200 ≤95 无
