American standard UNS N08811 tshuaj muaj pes tsawg leeg, txhua yam khoom thiab siv
UNS N08811 yog ib qho austenitic low-carbon npib tsib xee-hlau-chromium alloy nyob rau hauv tib series li Incoloy 800. Cov ntsiab lus cobalt hauv cov hlau no tuaj yeem tswj tau qis dua 0.01%.
UNS N08811 yog resistant rau ntau corrosive media. Nws cov ntsiab lus siab nickel ua rau nws tiv taus kev ntxhov siab corrosion tawg hauv cov dej corrosive. Cov ntsiab lus siab chromium muab nws zoo dua rau pitting thiab crevice corrosion cracking. Cov hlau no muaj kev tiv thaiv zoo rau nitric acid thiab organic acids, tab sis muaj kev tiv thaiv corrosion ntawm sulfuric acid thiab hydrochloric acid. Ntxiv nrog rau qhov ua tau ntawm pitting corrosion hauv halides, nws muaj qhov zoo corrosion kuj hauv oxidizing thiab non-oxidizing ntsev. Nws kuj muaj qhov zoo corrosion kuj nyob rau hauv dej, chav thiab sib tov ntawm chav, cua thiab carbon dioxide.
UNS N08811 muaj cov khoom nram qab no
● Zoo heev corrosion kuj nyob rau hauv tsis tshua muaj kub aqueous media mus txog 500 degree
● Zoo heev tiv thaiv kev ntxhov siab corrosion
● Kev ua tau zoo heev
UNS N08811 siv:
● Nitric acid condenser - resistant rau nitric acid corrosion
● Steam cua sov raj - cov khoom siv zoo
●Heating element tube - zoo txhua yam khoom
●Rau cov ntawv thov nyob rau hauv ib puag ncig txog li 500 degree, cov hlau yog muab rau hauv lub xeev annealed.
