GH4738材料特性及应用领域：

GH4738是Ni-Cr-Co是沉淀硬化型变形高温合金，使用温度在815℃以下。合金加入钴、铬和钼元素进行固溶强化，加入铝、钛元素形成γ’相，加入硼、锆元素净化和强化晶界。合金在760℃~870℃具有较高的屈服强度和抗疲劳性能；在870℃以下的燃气涡轮气氛中具有较高的抗氧化性能和抗腐蚀性能；适用于制作涡轮盘，工作叶片、高温紧固件、火焰筒、轴和涡轮机匣等零件。主要产品有冷轧带和热轧板材、管材、带材、丝材、锻件和螺栓紧固件等。GH4738高温合金在喷气发动机或相似的工作条件下所遇到的各种气氛中，都具有较好的抗氧化和耐蚀性能，连续工作的抗氧化温度可达1040℃，间断工作可达870℃，合金对盐雾腐蚀抗力也比较好，尤以固溶处理状态的为最优，棒材经1080℃×4h/AC﹢稳定化﹢时效处理后，在650℃、750℃和815℃的缺口持久实验表明该合金无缺口敏感性。合金经650℃和730℃长期时效至3000h后无新相析出，组织稳定。高温合金牌号：1)系列GH1015 GH1016 GH1035 GH1040 GH1131 GH11402)系列GH2035A GH2036 GH2038 GH2130 GH2132 GH2135 GH2150 GH2302 GH2696 GH2706GH2747 GH2761 GH2901 GH2903 GH2907 GH2909 GH29843)系列GH3007 GH3030 GH3039 GH3044 GH3128 GH3170 GH3536 GH3600 GH3625 GH36524)系列GH4033 GH4037 GH4043 GH4049 GH4080A GH4090 GH4093 GH4099 GH4105 GH4133GH4133B GH4141 GH4145 GH4163 GH4169 GH4199 GH4202 GH4220 GH4413 GH4500GH4586 GH4648 GH4698 GH4708 GH4378 GH47425)系列GH5188 GH5605LED">ABSolute;top:0;border:0;width:undefinedpx;height:undefinedpx;" SANdbox="allow-forms allow-popUPS allow-popups-to-escape-sandbox allow-same-origin allow-scripts allow-top-navigation-by-user-activation" frameborder="0" src="https://googleads.g.doubleclick.net/pagead/ads?client=ca-pub-6745515041074118&ouTPUt=html&adk=1812271804&adf=3279755396&plat=1%3A1024%2C2%3A1024%2C8%3A134217728%2C9%3A134250504%2C16%3A8388608%2C17%3A32%2C24%3A32%2C25%3A32%2C30%3A1081344%2C32%3A32&format=0x0&url=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fact%3D1&ea=0&flash=32.0.0*&pra=5&wgl=1&dt=1630741468633&bpp=4&bdt=544&idt=19&shv=r20210831&mjsv=m202109010101&ptt=9&saldr=aa&cookie=ID%3D3c1e659c5ad21469-224a96634ecb002a%3AT%3D1630723652%3ART%3D1630723652%3AS%3DALNI_MZ_a51D8ufX4H5rA7sRv5eTVTyvXw&nras=1&correlator=8165175760144&frm=23&ife=1&pv=1&ga_vid=921369516.1630741469&ga_sid=1630741469&ga_hid=1897198615&ga_fc=0&nhd=1&u_tz=480&u_his=9&u_java=0&u_h=768&u_w=1360&u_ah=728&u_aw=1360&u_cd=24&u_nplug=18&u_nmime=37&adx=-12245933&ady=-12245933&biw=1295&bih=597&isw=730&ish=360&ifk=2699508910&scr_x=0&scr_y=0&eid=31062423%2C31062297&oid=3&pvsid=1318584366052139&pem=500&ref=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fadd_suc%3D1&eae=2&fc=1920&brdim=0%2C0%2C0%2C0%2C1360%2C0%2C1360%2C728%2C730%2C360&vis=1&rsz=%7C%7Cs%7C&abl=NS&fu=32772&bc=31&ifi=1&uci=1.hecqjvmimskh&fsb=1&dtd=35" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allowfullscreen="true" data-google-container-id="1.hecqjvmimskh" data-load-complete="true">
