1材料特性2化学成分3力学性能4应用范围5供应商动态6其他信息
材料特性
播报编辑通过添加硫、磷元素提升切削加工性能，其热处理工艺（如淬火介质选择）与30号钢相似，但淬裂敏感性与30号钢相当或略差 [1] [3] [6-7]。热轧状态下的抗拉强度为510~655 MPa，冷拉状态可达600~825 MPa [8]。
化学成分
播报编辑主要成分范围如下 [3] [6] [8]：碳C:0.27～0.35、硅Si:0.15～0.35、锰Mn:0.70～1.00、硫S:0.08～0.15、磷P:≤0.06。
力学性能
播报编辑热轧状态：抗拉强度510~655 MPa，伸长率≥15%，硬度≤187 HB冷拉状态：抗拉强度600~825 MPa，伸长率≥6.0%，硬度174~223 HB [8]
应用范围
播报编辑适用于制造以下两类部件 [1] [4-5] [7]：1.高强度非热处理标准件（如螺栓、螺母）2.需后续热处理的结构件
供应商动态
播报编辑2012-2016年：天津市川崎特金属制品有限公司、宁波高新区金诚德金属材料科技有限公司等曾供应该材料 [1] [4] [7]；截至2025年：东莞市集田金属材料有限公司、东莞市合圣模具钢材经营部等企业代理销售 [2-3] [6]。
其他信息
播报编辑交货状态需在合同中明确标注热轧或冷拉，冷拉状态加工硬化效应显著 [5-6] [8]。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":161384,"lemmaTitle":"","lemmaDesc":"低硫磷复合易切削钢的牌号","lemmaType":0,"uid":80726909,"uname":"ydmouldsteel","createTime":1253072744,"updateTime":1747928531,"isDefault":0,"isDeleted":0,"rank":1,"extData":{"audit_comment_category":2,"isBaikeV6":1,"isFrontV6":1,"isSapp":0,"isWaitForPersonal":false,"is_locked":0,"kpdClassify":[{"id":337502,"name":"工业产品"}],"lemmaId":2809956,"lemma_id":2809956,"naturalAdConf":{"industrial":true},"newEditor":1,"pass_count":11,"subLemmaId":2809956,"updateTime":1747928532,"wapEdit":0},"extFlag":0,"versionId":639858242,"versionUid":6850221331,"versionUname":"夏日限定橘子汽水","versionCreateTime":1747928530,"catalog":[{"level":1,"title":"材料特性","index":"1","uuid":"i1op6wm596","height":28},{"level":1,"title":"化学成分","index":"2","uuid":"i1op6wm8uf","height":28},{"level":1,"title":"力学性能","index":"3","uuid":"i1op6wmakw","height":28},{"level":1,"title":"应用范围","index":"4","uuid":"i1op6wmcxh","height":28},{"level":1,"title":"供应商动态","index":"5","uuid":"i1op6wmeuz","height":28},{"level":1,"title":"其他信息","index":"6","uuid":"i1op6wmh8s","height":28}],"abstract":[],"abstractAlbum":{"content":[{"albumId":1,"src":"aa59892b25b4eed1e7cd4044","desc":"(1.0726)易切削钢","width":280,"height":210,"uuid":"pcd4044"},{"albumId":1,"src":"9e3df8dcd100baa17c1d7bc34d10b912c8fc2e90","width":750,"height":495,"uuid":"wapc2e90"}],"desc":"概述图册","total":2,"coverPic":{"albumId":1,"url":"https://bkimg.cdn.bcebos.com/pic/aa59892b25b4eed1e7cd4044?x-bce-process=image/resize,m_lfit,w_536,limit_1/quality,Q_70","src":"aa59892b25b4eed1e7cd4044","origSrc":"aa59892b25b4eed1e7cd4044","desc":"(1.0726)易切削钢","width":280,"height":210,"uuid":"pcd4044"},"wapPic":{"src":"9e3df8dcd100baa17c1d7bc34d10b912c8fc2e90","origSrc":"aa59892b25b4eed1e7cd4044","width":750,"height":495,"uuid":"gpkajq5lxz"}},"reference":[{"type":1,"title":"供应低硫磷复合易切削钢","site":"马可波罗网主站","publishDate":"2012-09-15","index":1,"uuid":"i1op6wevk3","encodeUrl":"533aYdO6cr3_z3kATKWNxP72NynFPoz5u-XSAbFzzqIP0XOpS4bsVIl87dY0--doGASFs5dvL8YHmey_WQ9YuqJUILRpXbQinXf2WzLKy7zu_8dp3owY"},{"type":1,"title":"【东莞代理低硫磷复合易切削钢 易切削圆棒图片】东莞代理低硫磷复合易切削钢 易切削圆棒图片大全 -
