我国冷镦钢的开发生产已取得了初步成果，但质量还有待进一步提高。了解和掌握国内外冷镦钢的生产技术水平，在重钢公司现有的生产设备条件下，借鉴其它钢厂的成功经验，在生产过程中坚持优化冷镦钢全部工序的工艺技术规程，进行铁水预处理、转炉冶炼、钢包精炼、连铸机连铸、加强坯料加热、中间轧制、吐丝温度控制，严格按标准执行，可以生产出市场要求性能的冷镦钢。冷镦钢包括优质碳钢、合金结构钢、双相钢、轴承钢和不锈钢。冷镦钢按其生产工艺路线又可分为非热处理型、调质型、非调质则及表面硬化型，6.8级以下的紧固件多采用非热处理型中碳和低碳冷镦钢制造，成品紧固件无需淬火回火处理。高强度紧固件用钢通常为调质型中碳钢或中碳合金钢，成品紧固件需进行淬火回火处理，也可选用非调质钢、硼钢、F-M双相钢或低碳马氏体钢表面硬化型钢为低碳钢和低合金钢（ML18A、M120Cr等），主要用于制造自攻螺钉和紧固螺钉，成品螺钉需经渗碳、渗氮等表面硬化处理。易切削钢SUM11SUM12SUM21SUM22SUM22LSUM23SUM23LSUM24LSUM25SUM31SUM31LSUM32SUM41SUM42SUM43冷墩钢：SWRCH6RSWRCH8RSWRCH10RSWRCH12RSWRCH15RSWRCH17RSWRCH6ASWRCH8ASWRCH10ASWRCH12ASWRCH15ASWRCH16ASWRCH18ASWRCH19ASWRCH20ASWRCH22ASWRCH10KSWRCH12KSWRCH15KSWRCH16KSWRCH17KSWRCH18KSWRCH20KSWRCH22KSWRCH24KSWRCH25KSWRCH27KSWRCH30KSWRCH33KSWRCH35KSWRCH38KSWRCH40KSWRCH41KSWRCH43KSWRCH45KSWRCH48KSWRCH50K弹簧钢：SPS1SPS3SPS4SPS5SPS5ASPS6SPS7SPS8SPS9STB1STB2STB3STB4STB5SH590PSH590S压力容器用钢板：SPPV235SPPV315SPPV355SPPV450SPPV490S***45S***95SEV345SLA1235SLA1325SLA1360SCMV1SCMV2SCMV3SCMV4SCMV5SCMV6SBB410SBB450SBB450MSBB480SBB480MSBB42SBB46SBB46SBB46MSBB49SBB49MHRS1HRS2HRS3HRS4STHA12STHA13STHA20STHA22STHA23STHA24STHA25STHA26机械结构钢：STKM11ASTKM12ASTKM12BSTKM12CSTKM13ASTKM13BSTKM13CSTKM14ASTKM14CSTKM15ASTKM15CSTKM16ASTKM16CSTKM17ASTKM17CSTKM18ASTKM18BSTKM18CSTKM19ASTKM19CSTKM120ASCr420TKSCM415TKSCM418TKSCM420TKSCM430TKSCM435TKSCM440TKMSWR6MSWR8MSWR10MSWR12MSWR15MSWR17MSR20MSWR22HSWR27HSW***HSWR37HSWR42AHSWR42BHSWR47AHSWR47BHSWR52AHSWR52BHSWR57AHSWR57BHSWR62AHSWR62BHSWR67AHSWR67BHSWR72AHSWR72BHSWR77AHSWR77BHSWR82AHSWR82B瑞典碳素结构钢：12111225122612321233123412501265130013101311131213131330133113321350135713701410140014121413141414211422142314241430143114321434143514501500151015501555157216001650165516601665167216741678合金结构钢：20852090210221022103210621072108211021122114211621172120212121222127212821302131213221342135214221432144214521652168217221732174220322162218222522282230223122332234224022442245225322542258250625102511251225142515252025232530253225342536254121642615262426252632263426422644265226542662266429122940弹簧钢：1770177417781912191419221926194019571973***用钢：S355G2+NS355G3+NS355G5+MS355G6+MS355G7+NS355G7+MS355G8+NS355G8+MS355G9+NS355G9+MS355G10+NS355G10+MS420G1+QS420G1+MS420G2+QS420G2+MS460G1+QS460G1+MS460G2+QS460G2+MS355G1+NS355G13+NS355G13+QS420G5+QS460G5+QS355G1+NS355G14+NS355G14+QS355G14+NS355G15+QS420G6+QS460G6+QS355G1S355G1+NS355G4S355G4+MS355G11S355G11+NS355G11+MS355G12S355G12+NS355G12+MS420G3S420G3+MS420G4S420G4+MS460G3S460G3+MS460G4S460G4+M调质钢：C10EC15E17Cr316MnCr5C22EC30EC35E***0E***5EC50EC55EC60E25Mn25CrMo434CrMo442CrMo4C55SC60SC67SC75SC85SC90SC100SC125S48Si756Si775Ni8125Cr2102Cr651CrV480CrV2英国低合金钢：P355MP355ML1P335ML2P420MP420ML1P420ML2P460MP460ML1P460ML2P355QBP355QHP355QL1P355QL2P460QP460QHP460QL1P460QL2P500QP500QP500QHP500QL1P500QL2P690QP690QHP690QL1P690QL2S235J0WS235J2WS355J0WPS355J2WPS355J0WS355J2G1WS355J2G2WS355K2G1WS355K2G2WS345J0WHS345GWJS345J0WPTC22EC22RC35C35EC35R***0***0E***0R***5***5E***5RC50EC50RC55C55EC55RC60C60EC60R28Mn6040A04040A10040A12080A15080A15080A17080A42070M55080M15060A72060A78120M36130M15150M19150M36214M15070M20070M26080A15080M30070M55080M40080M46070M55060A62080M36合金结构钢：605M36606M36635M15355M13665M17708H37708M40709M40722M24805A22805H22805M22808M17817M40820H17822H17822M17826M40835H15835M15835M30945M38523H15523M15527A17827H17527M17590A15590H17590M17635A14635H15635M15637A16637H17637M17655H13655M13665H17665H20665H23665M17665M20665M23708H20708M20708M40709H40720M32722M24805A17805A20805A22805H17805H20805H22805M17805M20805M22808H17808M17815H17815M17820H17820M17822M17822M17832H13832M13835H15835M15M987M39905M39易切削钢：130M15212M36214M15216M44210A15210M15214A15214M15280M0111***n3011***nPb3011***n3711***nPb3710S2010SPb2015***n1335S2035SPb2036***n1436***n1436***nPb1438***n2838***nPb2844***n2844***nPb2846S2046SPb20冷墩钢：C2C***CC8CC10CC15CC17CC20C8MnSi7C10E2CC15E2CC17E2CC20E2C10NiCr5-412CrMo412NiCr3-215B216MnCr516MnCrB516MnCrS517Cr317CrNi6-617CrS318B218CrMo418CrMoS418MnB420MnCrS520MnCr420MnCrS420NiCrMo2-220NiCrMoS2-220NiCrMoS6-422MnB4C35ECC35RC***5EC***5RC25CrMo425CrMoS434Cr434CrMo434CrNiMo637Cr437CrMo437Mo238Cr241Cr441CrS441NiCrMo7-3-242CrMo442CrMoS446Cr217B217MnB420MnB423B223MnB427MnB428B230MnB430MoB131CrMoB2-132CrB433B236CrB436MnB437MnB538B2弹簧钢：38Si745SiCrV6-246Si746SiCrMo650SiCrMo651CrV452CrMoV452SiCrNi554SiCr654SiCrV655Cr356Si756SiCr760Cr360CrMo3-160CrMo3-260CrMo3-360SiCrV761SiCr7251A85251A60251H60525A58525A60525H60525A61658A57658A57我公司销售网络遍及***二十多个省市。按照持续改进的要求，公司的质量管理体系满足GB/T19001--2008/ISO9001：2008标准要求。公司仓库配有龙门锯床、剪板机、切割机、氧割、焊割等，可锯切600mm以下材料，***打包、运输、仓储等服务。。圣帆公司经营的宗旨：在维持好经销商渠道的同时，积极拓展、服务终端客户，力求成为厂家的渠道服务商，帮助钢厂提升产品价值空间，满足终端客户的需求，实现厂家、渠道、终端的三方共赢。圣帆公司的经营理念：实事求是，***，效率优先。年轻人一直是支持发展的骨干，朝气蓬勃、勇于创新是我们的优势。真诚欢迎各界朋友和用户与我们合作，愿与大家一道携手共进，共创美好未来.欢迎各界新老朋友惠顾本公司，公司将以高质量、***格、优质的服务迎接您！)
