GH2706和GH698哪个好加工 欢迎您来电咨询!周工/TEL:1-3-8---1616---6343(wei信同号) GH2706是Fe-Ni-Cr基沉淀硬化型变形高温合金,使用温度在550℃-650℃以下,该合金是GH4169合金的改型合金,其特性类似GH4169合金。由于合金中铌含量的降低,使其具有更佳的生产工艺性能、冷工性能和焊接性能。合金在700℃以下具有较高的强度、良好的抗氧化及耐腐蚀能力。该合金可以生产大尺寸和*尺寸的高温合金产品,适宜制作航空发动机机匣、扩散器壳体、涡轮盘和紧固件等零部件,也可以用于制造适合循环发电用燃气轮机的大直径环件。主要产品有棒材、锻件、环件、薄板和带材等。GH2706高温合金已用于制造发动机、高压压气机、延伸机匣等零部件。该合金具有很宽的热加工温度区间,在850℃-1150℃范围之间具有较高的塑性。变形速率为0.01时,在900℃-1100℃很快进入稳态流变阶段,随后真应力的变化很小,对于大定型的开坯和热加工极为有益。合金三段热处理中843℃*3h为稳定化处理,经过处理后,在晶界上存在大量η相,η相的存在有利于持久性能的提高。热处理制度:热轧棒材、锻制棒材、锻件:925-980℃,水冷+845℃保温3小时+720保温8小时以每小时55℃降温至620℃保温8小时,安冷。HBS>285。密度:8.06LED">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%3A32776%2C2%3A32776%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=1625643978120&bpp=4&bdt=260&idt=107&shv=r20210630&ptt=9&saldr=aa&cookie=ID%3Dc7bd5bd9f711b61d-2294513835ca00c3%3AT%3D1625643117%3ART%3D1625643117%3AS%3DALNI_MaQOqApP_4PCrLJuCjqSTNxFECung&nras=1&correlator=7942765014464&frm=23&ife=1&pv=1&ga_vid=1963336709.1625643978&ga_sid=1625643978&ga_hid=1555634874&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=15&u_nmime=33&adx=-12245933&ady=-12245933&biw=1295&bih=597&isw=730&ish=360&ifk=2699508910&scr_x=0&scr_y=0&eid=31060973%2C31061745%2C42531226%2C31061218%2C31061421&oid=3&pvsid=243122169064392&pem=911&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=1.3kl92mv6liy7&fsb=1&dtd=139" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allowfullscreen="true" data-google-container-id="1.3kl92mv6liy7" data-load-complete="true"> |
