Cov ntsiab lus siab nickel muab cov alloy zoo kev ntxhov siab corrosion cracking kuj.
Corrosion kuj yog qhov zoo hauv ntau yam xov xwm, xws li sulfuric, phosphoric, nitric thiab organic acids, alkali hlau xws li sodium hydroxide, potassium hydroxide thiab hydrochloric acid daws.
Kev ua tau zoo tag nrho ntawm Incoloy 825 yog pom nyob rau hauv lub tshuab hluav taws xob sib txuas nrog ntau yam kev tawm tsam, xws li sulfuric acid, nitric acid thiab sodium hydroxide, txhua yam ua tiav hauv tib lub cuab yeej.
