Nimonic 81化学成分性能作用  

   1.镍；能提高钢的强度和韧性，提高淬透性．含量高时，可显著改变钢和合金的一些物理性能，提高钢的抗腐蚀能力．  

   2.铬；能提高钢的淬透性和耐磨性，能改善钢的抗腐蚀能力和抗氧化作用．

   3.钼；可明显的提高钢的淬透性和热强性，防止回火脆性，提高剩磁和娇顽力

   4.钨；能提高钢的红硬性和热强性，并能提高钢的耐磨性．

常用硬度：

   ①布氏硬度以HB[N(kgf/mm2)]表示（HBSHBW）（参照GB/T231－1984），生产中常用布氏硬度法测定经退火、正火和调质的钢件，以及铸铁、有色金属、低合金结构钢等毛胚或半成品的硬度。   ②洛氏硬度可分为HRA、HRB、HRC、HRD四种，它们的测量范围和应用范围也不同。一般生产中HRC用得最多。压痕较小，可测较薄的材料和硬的材料和成品件的硬度。   ③维氏硬度以HV表示（参照GB/T4340-1999），测量极薄试样 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" src="https://googleads.g.doubleclick.net/pagead/ads?client=ca-pub-6745515041074118&ouTPUt=html&adk=1812271804&adf=3279755396&plat=1%3A1024%2C2%3A1024%2C3%3A32%2C4%3A32%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=1637052146034&bpp=8&bdt=223&idt=131&shv=r20211111&mjsv=m202111080101&ptt=9&saldr=aa&cookie=ID%3D3723971ac5773f3c-223e30f3a8ce00a6%3AT%3D1636976065%3ART%3D1636976065%3AS%3DALNI_MZKetPvsxcLQ1xKArBk1xQkjnCLdw&nras=1&correlator=1929500577360&frm=23&ife=1&pv=2&ga_vid=1290262660.1637052146&ga_sid=1637052146&ga_hid=940153297&ga_fc=0&nhd=1&u_tz=480&u_his=13&u_h=768&u_w=1360&u_ah=728&u_aw=1360&u_cd=24&DMC=2&adx=-12245933&ady=-12245933&biw=1295&bih=597&isw=730&ish=360&ifk=2699508910&scr_x=0&scr_y=0&eid=31063183%2C44748553&oid=2&pvsid=476434787623035&pem=120&tmod=1048698691&ref=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php&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=1.9hpurd23tgvp&fsb=1&dtd=166" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allowfullscreen="true" data-google-container-id="1.9hpurd23tgvp" data-load-complete="true">
