GH4049高温合金是一种时效硬化的镍基高温合金，由镍、钼、铝等元素组成。镍含量约为70%。GH4049高温合金具有冷热加工性能，950℃以下高温强度高，缺口敏感性低，抗氧化性和疲劳强度好，但单一热加工塑性差。或者电渣重熔可以提高其热加工塑性。 GH4049高温合金能在600～1200℃的高温下承受一定的应力，具有抗氧化或耐腐蚀的性能。因此，它可用于制造高温部件，如飞机和工业燃气轮机的涡轮叶片、导向叶片、涡轮盘、高压压缩机盘和燃烧室。还可用于制造航天器、火箭发动机反应堆、石油化工设备、煤炭转化等能量转换装置。其交货状态较为规律，品类较多，如无缝管:固溶体+酸白，定长；板材:清洗、修边；焊管:固溶酸性白+RT%探伤，锻造:退火+车削；在棒料锻造状态下，表面抛光或磨光；经过冷轧、固溶软化后，脱氧皮材以固溶酸洗、盘或直带、固溶直带、精抛光等形式交付。LED">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" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" 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%2C41%3A32&format=0x0&url=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fact%3D1&ea=0&pra=5&wgl=1&dt=1667983376318&bpp=4&bdt=49&idt=52&shv=r20221101&mjsv=m202211020101&ptt=9&saldr=aa&cookie=ID%3D0da373f4a3ff73cb-22b42752a9d50069%3AT%3D1660901290%3ART%3D1660901290%3AS%3DALNI_MbdkGJwpvDSGF0-g9iDL2oZe3-MLg&gpic=UID%3D000008c8495d7805%3AT%3D1660901290%3ART%3D1667982774%3AS%3DALNI_MZiXWZnUGAfuCyowBQV3pwhKdZ4Rg&nras=1&correlator=3566948440427&frm=23&ife=1&pv=2&ga_vid=1957753191.1667983376&ga_sid=1667983376&ga_hid=561507783&ga_fc=0&nhd=1&u_tz=480&u_his=6&u_h=720&u_w=1280&u_ah=672&u_aw=1280&u_cd=24&u_sd=1.5&DMC=8&adx=-12245933&ady=-12245933&biw=1257&bih=568&isw=730&ish=360&ifk=2699508910&scr_x=0&scr_y=0&eid=44759876%2C44759927%2C44759837%2C44773809%2C42531706%2C31070617%2C44775017&oid=2&pvsid=635301103974835&tmod=717747881&uas=0&nvt=1&ref=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fadd_suc%3D1&eae=2&fc=1920&brdim=0%2C0%2C0%2C0%2C1280%2C0%2C1280%2C672%2C730%2C360&vis=1&rsz=%7C%7Cs%7C&abl=NS&fu=32772&bc=31&ifi=1&uci=1.75ax4pg4gmhq&fsb=1&dtd=66" data-google-container-id="1.75ax4pg4gmhq" data-load-complete="true"> |
