INCLOLOY 825 (UNS N08825 / NS142)
Kushandiswa
Alloy 825 imhando ye austenitic nickel-iron-chromium alloy inotsanangurwawo nekuwedzera molybdenum, copper uye titanium. Yakagadzirwa kuti ipe simba risingakuvadzi nharaunda dzakawanda, zvese zvinopisa uye zvinoderedza kupisa.
Alloy 825 yakagadzirwa kuti ipe simba rekudzivirira nharaunda dzakasiyana-siyana dzinoparadza, dzinoita kuti ioxidize uye dzideredze. Nehuwandu hwe nickel huri pakati pe38%–46%, rudzi urwu runoratidza simba rekudzivirira kuputika kwe stress corrosion (SCC) kunokonzerwa nema chloride ne alkalis. Hunhu hwe nickel hwakakwana kuti hudzivirire kuputika kwe chloride-ion stress-corrosion. Nickel, pamwe chete ne molybdenum ne copper, inopawo simba rekudzivirira nharaunda dzakadai sedzine sulfuric ne phosphoric acids.
Chromium nemolybdenum zvinopawo hunhu hwakanaka hwekudzivirira makomba munzvimbo dzese kunze kwemhinduro dzechloride dzinopisa zvakanyanya. Ichishandiswa sechinhu chinoshanda munzvimbo dzakasiyana-siyana dzemaitiro, alloy 825 inochengetedza hunhu hwakanaka hwemakanika kubva pakupisa kwe cryogenic kusvika ku1,000° F.
Kuwedzerwa kwetitanium kunoita kuti Alloy 825 isanyanya kusimba kana yakabatana, zvichiita kuti alloy isanyanya kusimba mushure mekusangana nekupisa kwakasiyana-siyana kunogona kusimba simbi dzisina kusimba. Kugadzirwa kweAlloy 825 kwakajairika kune nickel-base alloys, zvinhu zvichigona kugadzirwa nyore nyore uye kusundirwa nenzira dzakasiyana-siyana.
Chinhu ichi chine maumbirwo akanaka kwazvo, akafanana ne nickel-base alloys, zvichiita kuti chinhu chacho chikwanise kukotama kuita radii diki kwazvo. Kuchiisa mushure mekukotama hazviwanzodiwi.
Yakafanana ne alloy 800 asi ine simba rekudzivirira ngura yemvura. Inodzivirira zvakanyanya ngura yekuderedza uye oxidizing acids, ngura dzinoputika, uye ngura dzinowanikwa munzvimbo dzakadai segomba rinoputika uye ngura inochekwa. Alloy 825 inonyanya kudzivirira sulfuric nephosphoric acids. Iyi nickel steel alloy inoshandiswa pakugadzira makemikari, michina yekudzora kusvibiswa, mapaipi emafuta negasi, kugadzirisa mafuta enyukireya, kugadzira acid, uye michina yekubika.
