咨询︰①⑦③○①⑧⑥⑧⑦⑥③(微信同号) Inconel 725(UNS N07725)是一种镍基合金,对许多水性环境具有很强的耐受性,并且具有极高的强度可时效硬化。它具有与Inconel 625基本相同的耐腐蚀性,Inconel 625广泛用于各种腐蚀性环境。 Inconel 725特别耐受含有二氧化碳,氯化物和liu化氢的介质,例如在深酸气井中遇到的介质。在这样的环境中,它可以抵抗一般腐蚀,点蚀,liu化物应力开裂(氢脆)和应力腐蚀开裂。Inconel 725还具有耐盐水和海水腐蚀性。Inconel 725满足了在深层,极端恶劣的石油和***生产环境中高温环境抗裂性的需求。由于较高的钼含量,它在较高温度下在较高水平的H 2 S中提供更好的抗裂性。Inconel 725化学成分Ni% 铬% 铁% Mo% 铌% Ti% 铝% 锰%55.0-59.0 19.0-22.5 余量 7.0-9.5 2.75-4.0 1.0-1.7 ≤0.35 ≤0.35Si% P% C% S%≤0.2 ≤0.015 ≤0.03 ≤0.01名称美国N07725产品规格Inconel 725电线:ASTM B805Inconel 725棒材:ASTM B805Inconel 725物理特性密度:8.31克/立方厘米熔点:1271℃-1343℃Inconel 725机械性能回火:时效拉伸强度:≥1137 MPa屈服强度:≥827MPa伸长率:20%Inconel 725用途:可时效硬化的合金725用于衣架,落地接头,侧袋心轴和酸性气体服务中的抛光孔容器。也用于船舶应用中的高强度紧固件。它结合了高强度和高硬度,使合金725成为聚合物挤出模头的合适选择。镍合金具有优良的耐蚀性、强度、韧性、冶金稳定性、可加工性及可焊接性的总合性能。许多镍合金又具有sUPEr的耐热性能,而成为要求耐化学腐蚀和高温强度用途的理想选择。镍合金比不锈钢更贵。但是,使用初始成本而不是根据使用寿命周期进行比较的话,会出现错误的想法。例如,Ni-Cr-Mo合金成本大致是18Cr-8Ni不锈钢的5倍,是super奥氏体不锈钢成本的大约2倍。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%3A1048576%2C2%3A1048576%2C9%3A32776%2C16%3A8388608%2C17%3A32%2C24%3A32%2C25%3A32%2C30%3A1048576%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=1619076031726&bpp=29&bdt=M&idt=112&shv=r20210419&cbv=r20190131&ptt=9&saldr=aa&cookie=ID%3Df43b826f12745ccd-2268431f63c700b7%3AT%3D1618380579%3ART%3D1618380579%3AS%3DALNI_MamEblcYoWowg_oAMi_al7xjlPzyQ&nras=1&correlator=8498205411264&frm=23&ife=1&pv=2&ga_vid=1728925304.1619076032&ga_sid=1619076032&ga_hid=1851218224&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=1110&bih=923&isw=730&ish=360&ifk=2699508910&scr_x=0&scr_y=0&eid=44740079%2C44739992&oid=3&pvsid=454815615710931&pem=127&ref=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fadd_suc%3D-1&eae=2&fc=1920&brdim=793%2C12%2C793%2C12%2C1920%2C0%2C1122%2C1031%2C730%2C360&vis=1&rsz=%7C%7Cs%7C&abl=NS&fu=4&bc=31&ifi=1&uci=1.8i6j0sn5xwau&fsb=1&dtd=199" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allowfullscreen="true" data-google-container-id="1.8i6j0sn5xwau" data-load-complete="true" frameborder="0"> |
