咨询︰①⑦③○①⑧⑥⑧⑦⑥③(微信同号) GH3170是Ni-Cr-Co基固溶强化型变形高温合金，其成分特点是含有Co20%+Cr20%和W20%。并加入微量的镧元素强化晶界。合金在1000℃具有较高的强度和抗蠕变性能，在1100℃-1200℃仍有较好的秒强度。合金具有优良的性能和良好的冷成形和焊接工艺性能。主要产品为板材。合金已用于制作航空发动机加力燃烧室调节片零件。该合金的性能水平接近美国固溶强化型钴基合金HA188和MAR-M918。推荐用于航空发动机的燃烧室和高温部件，以及用作火箭发动机的喷管材料。合金在900℃和1000℃长期时效后析出μ相，使合金的室温塑性下降，但仍可以满足使用要求。牌号: GH3170C(％): ≤0.06Cr(％): 18.0～22.0Mo(％): —Ni(％): 余量Co(％): 15.0～22.0W(％): 18.0～21.0Al(％): ≤0.5Nb(％): —Ti(％): —B(％): ≤0.005Fe(％): —Mn(％): —(％): Zr0.1～0.2,La0.1～0.3热处理制度冷轧板、热轧板：1190℃-1240℃，空冷或炉冷。密度：9.34 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" src="https://googleads.g.doubleclick.net/pagead/ads?client=ca-pub-6745515041074118&ouTPUt=html&adk=1812271804&adf=3279755396&plat=1%3A1081352%2C2%3A1081352%2C9%3A32776%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=0&pra=5&wgl=1&dt=1618479145059&bpp=21&bdt=M&idt=89&shv=r20210413&cbv=r20190131&ptt=9&saldr=aa&cookie=ID%3Df43b826f12745ccd-2268431f63c700b7%3AT%3D1618380579%3ART%3D1618380579%3AS%3DALNI_MamEblcYoWowg_oAMi_al7xjlPzyQ&nras=1&correlator=2248482567710&frm=23&ife=1&pv=2&ga_vid=455536107.1618479145&ga_sid=1618479145&ga_hid=192453398&ga_fc=0&nhd=1&u_tz=480&u_his=50&u_java=0&u_h=1080&u_w=1920&u_ah=1040&u_aw=1920&u_cd=24&u_nplug=0&u_nmime=0&adx=-12245933&ady=-12245933&biw=1209&bih=901&isw=730&ish=360&ifk=2699508910&scr_x=0&scr_y=0&eid=42530672%2C44740079&oid=3&pvsid=3232938910087120&pem=127&ref=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fadd_suc%3D1&eae=2&fc=1920&brdim=703%2C0%2C703%2C0%2C1920%2C0%2C1221%2C1045%2C730%2C360&vis=1&rsz=%7C%7Cs%7C&abl=NS&fu=4&bc=31&ifi=1&uci=1.3dqadif43xxh&fsb=1&dtd=176" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allowfullscreen="true" data-google-container-id="1.3dqadif43xxh" data-load-complete="true" frameborder="0"> |
