Alloy 825 Tubing
Alloy 825 yog ib qho austenitic nickel-hlau-chromium alloy kuj txhais los ntawm kev ntxiv ntawm molybdenum, tooj liab thiab titanium.Nws tau tsim los muab kev tiv thaiv tshwj xeeb rau ntau qhov chaw corrosive, ob qho tib si oxidizing thiab txo.Nrog rau cov ntsiab lus npib tsib xee nyob nruab nrab ntawm 38% -46%, qib no qhia tau hais tias tsis kam tiv thaiv kev ntxhov siab corrosion (SCC) cuam tshuam los ntawm chlorides thiab alkalis.Cov ntsiab lus chromium thiab molybdenum kuj muab cov pitting zoo nyob rau hauv txhua qhov chaw tshwj tsis yog muaj zog oxidizing chloride daws.Siv los ua cov khoom siv tau zoo nyob rau hauv ntau yam txheej txheem ib puag ncig, alloy 825 tswj cov khoom siv zoo los ntawm qhov kub thiab txias txog li 1,000 ° F.
