Material Technical Standards
GB/T 14992 Kurongeka uye mamakisi epamusoro-tembiricha alloys uye intermetallic makomisheni emhando yepamusoro-tembiricha zvinhu.
GJB 1952A Tsanangudzo yeinotonhora yakakungurutswa pepa repamusoro tembiricha alloy yekushandiswa kwendege

Feature
GH99 iNi-Cr yakavakirwa mvura inoomesa deformation yakakwirira tembiricha alloy, inogona kushandiswa kwenguva yakareba iri pasi pe900 ° C, uye nguva pfupi tembiricha yepamusoro inogona kusvika 1000 ° C. GH99 alloy inosimbiswa nekuwedzera chromium, cobalt, tungsten uye molybdenum yekusimbisa mhinduro yakasimba, aruminiyamu uye titanium kuti iite kukwegura-kusimbiswa kwezvikamu, uye boron, cerium uye magnesium kuchenesa nekusimbisa miganhu yezviyo.GH99 alloy ine yakakwirira yekupisa simba, kugadzikana kwekugadzirisa uye kutonhora kwekugadzirisa zvinhu, kugadzikana kwekugadzirisa uye kutonhora kwekugadzirisa zvinhu. GH99 alloy ine high thermal simba, kugadzikana kwesangano, uye ine zvinogutsa kupisa uye kutonhora kugadzirisa kuumba uye welding process performance.GH99 inokodzera kugadzirwa kweaero-engine conmbustion chambers uye makamuri ekupisa mafuta uye mamwe e-high-temperature welded structural parts.Zvigadzirwa zvikuru zveGH99 zvinopisa, platerolled, wiresrolled uye fortersrolled. Iine alloy yakagadzirwa nehombe ndiro chimiro, inogona kushandiswa zvakananga mushure mekugadzirisa kwakasimba Kurapa pasina kuchembera Kurapa. Iyo alloy haina kuwanikwa iine chero zvikamu zvinokuvadza mushure mekukwegura kwenguva refu pa700 ℃ ~ 950 ℃.
