321不锈钢奥氏体型中文名321不锈钢日本牌号SUS321英国牌号304S12、321920德国牌号X10CrNiTi189别称奥氏体不锈钢特性耐磨蚀性、耐高温、抗蠕变性应用产业应用于抗晶界腐蚀性要求高的概述奥氏体不锈钢相当于国产06Cr18Ni11Ti美国牌号为：321、S32100、TP321特性321不锈钢其中的Ti作为稳定化元素存在,但它同时是热强钢种,在高温方面比316L要好的多.321不锈钢在不同浓度、不同温度的有机酸和无机酸中,尤其是在氧化性介质中具有良好的耐磨蚀性能,用于制造耐磨酸容器和耐磨设备的衬里、输送管道。321不锈钢是Ni-Cr-Ti型奥氏体不锈钢，其性能与304非常相似，但是由于加入了金属钛，使其具有了更好的耐晶界腐蚀性及高温强度。由于添加金属钛，使其有效的控制了碳化铬的形成。321不锈钢具有的优异的高温应力破断(StressRupture)性能及高温抗蠕变性能(CreepResistance)应力机械性能都优于304不锈钢。321不锈钢图片321不锈钢图片应用应用于抗晶界腐蚀性要求高的化学、煤炭、石油产业的野外露天机器，建材耐热零件及热处理有困难的零件，如：1.石油废气燃烧管道2.发动机排气管3.锅炉外壳，热交换器，加热炉部件4.柴油机用消音部件5.锅炉压力容器6.***运输车7.伸缩接头8.燃炉管道及烘干机用螺旋焊管物理性能化学成份碳C：≤0.08硅Si：≤1.00锰Mn：≤2.00硫S：≤0.030磷P：≤0.035铬Cr：17.00～19.00镍Ni：9.00～12.00钛Ti：≥5×C%力学性能抗拉强度σb(MPa)：≥520条件屈服强度σ0.2(MPa)：≥205伸长率δ5(%)：≥40断面收缩率ψ(%)：≥50硬度：≤187HB;≤90HRB;≤200HV热处理规范及金相***热处理规范：1)固溶920～1150℃快冷;2)根据需方要求可进行稳定化处理,热处理温度为850～930℃,但必须在合同中注明。3）固溶温度不能超过1066℃，超过的话，必须进行稳定化处理，以防止铬的析出。金相***：***特征为奥氏体型。●交货状态：一般以热处理状态交货，其热处理种类在合同中注明；未注明者，按不热处理状态交货。3不锈钢知识不锈钢（StainlessSteel）指耐空气、蒸汽、水等弱腐蚀介质和酸、碱、盐等化学浸蚀性介质腐蚀的钢，又称不锈耐酸钢。实际应用中，常将耐弱腐蚀介质腐蚀的钢称为不锈钢，而将耐化学介质腐蚀的钢称为耐酸钢。由于两者在化学成分上的差异，前者不一定耐化学介质腐蚀，而后者则一般均具有不锈性。不锈钢的耐蚀性取决于钢中所含的合金元素【上海同铸金属有色金属有限公司】***经营高温合金详细介绍如下：★中国高温合***号:GH1015GH1016GH1035GH1040GH1131GH1139GH1140GH2035AGH2036GH2038GH2130GH2132GH15GH16GH35GH40GH131GH139GH140GH35AGH36GH38AGH130GH132GH2135GH2150GH2302GH2696GH2706GH2747GH2761GH2901GH2903GH2907GH2909GH2984GH3007GH3030GH3039GH3044GH3128GH3170GH3536GH3600GH135GH150GH302GH696GH706GH747GH761GH901GH903GH907GH909GH984GH5KGH30GH44GH128GH170GH536GH600GH3625GH3652GH4033GH4037GH4049GH4080AGH4090GH4093GH4098GH4099GH4105GH4133GH4133BGH4141GH4145GH4163GH4169GH4199GH4202GH4220GH625GH652GH33GH37GH49GH80AGH90GH93GH98GH99GH105GH33AGH4133BGH141GH145GH163GH169GH199GH202GH220GH4413GH4500GH4586GH4648GH4698GH4708GH4710GH4738GH4742GH5188GH5605GH5941GH6159GH6783GH413GH500GH586GH648GH698GH708GH710GH738GH684GH742GH188GH605GH941GH159GH783K211K213K214K401K402K403K405K406K406CK407K408K409K412K417K417GK417LK418K418BK419K419HK11K13K14K1K2K3K5K6K6CK7K8K9K12K17K17GK17LK18K18BK19K19HK423K423AK424K430K438K438GK441K461K477K480K491K4002K4130K4163K4169K4202K4242K4536K4537K4648K4708K23K23AK26K430K38K38GK41K461K77K80K91K002K130K163K4169K202K242K536K537K648K708K605K610K612K640K640MK6188K825K605K10K612K40K40MK188K25DZ404DZ405DZ417GDZ422DZ422BDZ438GDZ4002DZ4125DZ4125LDZ640MDZ4DZ5DZ17GDZ22DZ22BDZ38GDZ002DZ125DZ125LDZ40MDD402DD403DD404DD406DD408DD3DD4DD6DD8HGH1035HGH1040HGH1068HGH1131HGH1139HGH1140HGH2036HGH2038HGH2042HGH35HGH40HGH68HGH131HGH139HGH140HGH36HGH38HGH42HGH2132HGH2135HGH2150HGH3030HGH3039HGH3041HGH3044HGH3113HGH3128HGH3367HGH3533HGH3536HGH3600HGH4033HGH4145HGH4169HGH4356HGH4642HGH4648HGH132HGH135HGH150HGH30HGH39HGH41HGH44HGH113HGH128HGH367HGH533HGH536HGH600HGH33HGH145HGH169HGH356HGH642HGH648FGH4095FGH4096FGH4097FGH95FGH96FGH97MGH2756MGH2757MGH4754MGH4755MGH4758MGH2756MGH2757MGH754MGH5KJG1101JG1102JG1201JG1202JG1203JG1204JG1301JG1302JG4006JG4006AJG4246JG4246ATAC-2TAC-2MTAC-3ATAC-3BTAC-3CTAC-3DTAC-1TAC-1BIC6IC6AMX246MX246A)★美国高温合金:40540640943043443918SR18Cr-2Mo446E-Brite26-126-1Ti29Cr-4Mo403410416422H-46MolyAscoloyGreekAscoloyJetheteM-152Almar363431Custom450Custom45515-5PH17-4PHPH13-8MoAM-350S40500S40900S43000S43400S43927S44600S44627S40300S41000S41600S42200S43100S15500S17400S13800S35000AM-35517-7PHPH15-7Mo304304L304N309310316316L316N31732134719-9DL17-14-CuMo20221621-6-9Nitronic32Nitronic33Nitronic60Carpenter18-18PlusS35500S17700S15700S30400S30403S30451S30900S31000S31600S31603S31651S31700S32100S34700K63198K63199S20200S21600S2190016-25-617-14CuMo19-9DLCarpenter20Cb-3Incoloy800Incoloy801Incoloy802N-155RA330Haynes25(L-605)Haynes188S-816Stellite6BUMCo-50HastelloyBHastelloyB-2HastelloyCHastelloyC-4HastelloyC-276HastelloyNHastelloySHastelloyWHastelloyXIncone1600Incone1601Incone1604Incone1617Incone1625NA-224Nimonie75RA-333A-286DiscaloyHaynes556Incoloy903PyrometCTX-1K63198N08020N0800N08801R30155N08330R30605R30188R30816N10001N10065N10002N06455N10276N10003N10004N06002N06600N06601N06625N06333K66286K66220V-57W-545AR-213MP-35NMP-159AstroloyD-979IN100IN102Incoloy901Incoloy1706Incoloy1718Incoloy1751IncoloyIX750M252Nimonic80ANimonic90Nimonic95Nimonic100Nimonic105Nimonic115Nimonic263Pyromet860Refractory26Rene4LRene95Rene100Udimet500Udimet520Udimet630Udimet700Udimet710UnitempAF2-1DAWaspaloyK66545R30035N09979K66979N13100N06102N09901N09706N07718N07750N07252N07080N07090N07041N07500N07001HAHCHDHEHFHHHIHKHLHNHPHP-50WZHTHUHWHXJ92605J93005J93403J92603J93503J94003J94224J94604J94213J94605A217A297A608A567A351B-1900HastelloyXIN-100IN-738XIN-792Inconel713CInconel713LCInconel718InconelX-750M-252MAR-M200MAR-M246MAR-M247NX188(DS)Rene77Rene80Rene100TRWNAS***IAUdimet500Udimet700Udimet710WaspaloyWAZ-20(DS)AiResist13AiResist213AiResist215Haynes21Haynes25,L-605Haynes151J-1650MAR-M302MAR-M322MAR-M509MAR-***18NASACo-W-ReS-816V-36WI-52X-40★英国高温合金:N75N80AN90N105N115N118N901N263NimonicPE11NimonicPE16NimonicPK33EPK57PE13C130C242C1023NimocastPE10NimocastPD16NimocastPD18NimocastPK24Stellite31MM002Haynes25★法国高温合金:ATV***oATVS2ATVS7ATVS7MoATGC1ATGEATGE2ATGFATGM2ATGRATGS3A
