哈氏合金紧固件,锆705紧固件,英科乃尔紧固件,蒙乃尔紧固件和特殊不锈钢紧固件(详见http://)我公司是进口哈氏合金(Hastelloy),蒙乃尔400/500(Monel400/500),英科乃尔(Inconel)和锆702/705)材料***经销商及上述特殊材料制造紧固件***制造商.这些特殊材料具有较好抗均匀侵蚀,优异抗局部腐蚀和应力裂纹腐蚀,耐海水腐蚀和耐高温特性因而,这些特殊材料被广泛用于石油,化工,制药,气体脱硫,电厂,造船,特别是醋酸和醋酐装置和许多其他行业.由于哈氏合金,英科乃尔和蒙乃尔材料具有高强度、高韧性和哈氏合金具有极强应变冷作硬化倾向力学特点,特别是用哈氏合金材料制造紧固件存在很大的难度和要求极其严格加工工艺.1995年,我工程技术人员在美国HaynesInterna-tionalCo.Ltd.(哈氏合金材料制造公司)学习哈氏合金材料性能和用途理论知识和哈氏合金材料制造设备的制造工艺,并带回大量技术资料.为确保制造优质特殊材料紧固件和在冷热交变状态受拉应力状态长期使用,在制造特殊材料紧固件全过程中以下三个技术要求特别重要:1.特殊材料:必须采用进口欧美特殊材料,因为欧美进口特殊材料严格执行ASTE材料规范其理化性能特别是耐腐蚀性能是稳和可靠的2.热加工工艺:由于哈氏合金,英科乃尔和蒙乃尔材料具有高强度,高韧性和哈氏合金具有极强应变冷作硬化倾向力学特点,在制造特殊材料紧固件时,在每个热加工过程中严格要求热加工和热处理温度控制,从而避免在特殊材料圆钢在冷拔至要求外径尺寸过程中和六角螺栓六角头在热锻打成型过程中产生微裂纹,一旦特殊材料六角头螺栓出现微裂纹,在冷热交变状态受拉应力状态使用会使微裂纹逐步扩大,在短期使用中使六角螺栓断裂.因而,严格控制整个制造中每个热加工过程特别重要,因而,制造优质特殊材料六角头螺栓要求特别高.a.哈氏B3锻打温度须控制在1232C°(开始锻打)和在982C°(结束锻打)b.哈氏C276锻打温度须控制在1232C°(开始锻打)和在954C°(结束锻打).3.机加工工艺:由于哈氏合金材料具有高强度、高韧性和极强应变冷作硬化倾向力学特点,哈氏合金紧固件机加工难度非常大.为保证螺栓和螺母制造精度和在标准范围内锁紧力以及符合紧固件制造和检验规范/标准,选择合适材料刀具非常重要,否则会出现紧固件螺纹深度过浅和烂牙不合格产品,大大降低紧固件使用寿命依据我公司拥有国外特殊材料供应商和成熟特殊材料紧固件制造技术和经验,提供以下哈氏合金,锆705,英科乃尔和蒙乃尔紧固件:(1).材料(制造紧固件进口材料):哈氏C276,哈氏B3,哈氏C22,锆705,蒙乃尔400,蒙乃尔500,英科乃尔600,英科乃尔800HT,英科乃尔625,英科乃尔825,904L,AL6XN,2205等(2).产品(进口材料制造)：a.六角螺栓/螺母:用于电厂脱硫和其他场合b.用于塔板联接紧固件:六角螺栓和螺母,圆头螺栓和螺母,单头铣扁螺柱,双头螺栓和螺母等c.内六角螺栓/螺母d.双头螺栓/螺母e.U型螺栓/螺母f.螺钉/螺母g,平垫片和弹簧垫圈等(3).标准/规范:GB5782,GB5783,GB70,GB6170,A***EB18.2.1,A***EB18.2.2,A***EB18.2.3.1M,A***EB18.2.4.1M,DIN931,DIN933,DIN603,DIN444ISO4014,ISO4017,ISO8677和***要求等4.主要业绩：从1997年起,我公司已为许多***国外独资,合资,上市公司,大型国内企业提供哈氏C276,哈氏B3,锆705,蒙乃尔400,英科乃尔材料紧固件，有些公司定制上万套哈氏C276紧固件(用于塔板联接)1.重庆扬子江乙酰(BP)化工有限公司醋酸装置(哈氏B3紧固件,哈氏C276紧固件,锆702紧固件)2.山东华鲁恒升化工股份有限公司醋酸和醋肝装置(哈氏B3紧固件,哈氏C276紧固件,锆702紧固件),英科乃尔825紧固件3.上海吴泾化工有限公司醋酸装置(哈氏B3紧固件,哈氏C276紧固件)4.河北英都气化有限公司醋酸装置(哈氏B3紧固件,哈氏C276紧固件,锆702紧固件)5.昊化宇航化工有限责任公司哈氏C276紧固件)6.拜耳材料科技（中国）有限公司哈氏B3紧固件,哈氏C276紧固件7.苏州诺华制药科技有限公司哈氏C276紧固件,蒙乃尔400紧固件8.巴斯夫应用化工有限公司哈氏C276紧固件,英科乃尔600紧固件9.大唐内蒙古多伦煤化工有限责任公司哈氏C276紧固件10.北京泽华化学工程有限公司哈氏B3紧固件(用于塔板联接),哈氏C276紧固件(用于塔板联接)11.河南神马股份有限公司哈氏C276紧固件(用于塔板联接),英科乃尔800HT紧固件12.烟台巨力异***酸脂有限公司哈氏C276紧固件如您有任何问题,请随时与我方联系,谢谢.陈志宝总经理MP:13801732820上海镍多化工设备制造有限公司上海市浦东新区金港路199弄6号805座TEL：021-58503107FAX：021-50336117E-mail:shndco@http://Hastelloyfasteners,Zirconium705fasteners,Inconelfasteners,Monelfasteneretc.OurcorporationisaimporterofsubmittingspecialmaterialsofHastelloy,Inconel,MonelandZirconium702/705aswellasamanufactureroffabricatingfastenersofabovematerial.Thefastenersarewidelyusedinthefieldsofaceticacid,aceticanhydride,petrochemical,chemical,pharmacy,power,marineandotherindustries.Astheattributesofthesespecialmaterialincludehighresistancetouniformattact,outstandinglocalizedcorrsionresistance,excellentstresscorrosioncrackingresistance,excellentseawaterresistance,wear-hightemperature.Thesespecialmaterialh***ebecomewidelyusedbytheoilandgas,chemicalprocessingindustries,phamaceutical,gasdesulfurizationindustries,power,marine,especiallyaceticacidandaceticanhydrideplantsandmanyindustries.AsithashighintensityandtenacityaswellasstongstrainhardeningtendencyforthemechanicalpropertiesofHastelloy,InconelandMonelalloy,Ithascertaindifficultytofabricatethefastenerandneedverystrictrequirementforprocessingtechnology.In1995,ourtechnicalpersonnelswassenttoHaynesInternationalCo.USA,whichisamanufacturertomanufacturingmaterialforHastelloyalloies,tostudytheoreticalknowledgeandfabricatingtechnologyforHastelloyalloiesandtookbackalottechnicaldocuments.Inordertoensuretofabricatethehighqualityfastenersforspecialmaterialandbeenuesdforalongtimeduringthestateofhotandcoldunderthetensilestress,itisparticularlyimportanttofabricatethefastenersforspecialmaterialaccordingtofollowingthreetechnicalrequirementduringwholefabricatingprocess.1.Specialmaterial:ItismusttoimportedspecialmaterialfromUSAandEurope.AsthespecialmaterialbemanufacturedaccordindtostrictexecutionASTEmaterialspecificati***/codes,itisstableandreliableforphysicalandchemicalproperties,especiallythepropertiesofcorrosionresistance2.Thermalprocessing:AsithasthemechanicalpropertiesofhighintensityandtenacityforHastelloy,InconelandMonelalloies,especiallythecharacteristicsofstongcoldhardeningtendencyforHastelloy.Ithascertaindifficultytofabricatethefastener.Duringfabricatingthefastenersofspecialmaterial,ithasstrictlyrequirementforcontrolingeachhot-workingandheattreatmenttemperatureprocess.Soitwillbe***oidedmicrocracksoccurringinthefastenersduringcolddrawntoaskingforouterdiametresizeofroundbarsandhot-forgingtoformhexheadofthebolts.Oncethemicrocracksinthefastenersb***ebeenoccurred,themicrocrackswillbegraduallygrowinthefastenersunderalternatingtensilestressofcoldingorheatingcondition.Thefastenerswillbefracturedintheshort-timeThus,strictlycontrolforwholemanufacturingprocessofeachheatingoperationisparticularlyimportant,Therefore,ithasmorestrictlyrequirementtofabricatehighqualityfastenersforspecialmateriala.Duringtheforgingprocess,the1232C°isstartforgingtemperatureand982C°isfinishedforgingtemperatureforHastelloyB3.b.Duringtheforgingprocess,the1232C°isstartforgingtemperatureand954C°isfinishedforgingtemperatureforHastelloyC2
