Daim ntawv thov Scope
800
1: Cua sov caij raj - zoo heev mechanical zog.
2: Acetic anhydride cracking-corrosion thaum lub sij hawm ua thermal.
Rau cov ntawv thov nyob rau hauv ib puag ncig mus txog 600 degree, cov hlau yog nkag rau hauv cov mob annealed.
Rau kev siv nyob rau hauv qhov kub thiab txias ib puag ncig, lub alloy yog muab nyob rau hauv ib tug tov annealed lub xeev.
800H 1.4958
1: Nitrogen condenser - resistant rau nitrate corrosion
2: Chav cua kub tube-zoo heev txhua yam khoom
3: Cua sov caij raj - cov khoom siv zoo heev
Rau cov ntawv thov nyob rau hauv ib puag ncig txog li 500 degree, cov hlau yog muab nyob rau hauv lub annealed mob.
Corrosion kuj
800 yog resistant rau ntau corrosive media. Nyob rau hauv aqueous corrosive ib puag ncig, lub corrosion kuj yog sib npaug rau cov austenitic stainless hlau. Cov ntsiab lus siab nickel ua rau nws tiv taus kev ntxhov siab corrosion tawg, thiab cov ntsiab lus chromium siab ua rau nws zoo dua rau pitting corrosion thiab crevice corrosion. Cov hlau muaj qhov ua tau zoo rau nitrate thiab organic corrosion, tab sis muaj kev tiv thaiv corrosion hauv sulfur * thiab ntsev *. Ntxiv nrog rau qhov ua tau ntawm pitting corrosion hauv halides, nws muaj qhov zoo corrosion kuj hauv oxidizing thiab non-oxidizing ntsev. Nws muaj kev tiv thaiv zoo heev rau oxidation thiab carbonization atmospheres thiab ib puag ncig thaj chaw uas oxidation thiab carbonization tshwm sim ntawm qhov kub thiab txias. Lub corrosion kuj ntawm hydrogen, nitriding thiab sulfur-muaj gases kuj zoo heev. Nyob rau hauv ib puag ncig daim ntawv thov tom kawg, qhov kev ua tau zoo yog qhov zoo dua nyob rau hauv oxidizing tej yam kev mob dua li txo cov mob.
800H tuaj yeem tiv thaiv corrosion los ntawm corrosive media. Nws cov ntsiab lus ntau dua nickel ua rau nws tiv taus kev ntxhov siab corrosion tawg nyob rau hauv aqueous corrosive tej yam kev mob. Cov ntsiab lus siab chromium muab nws zoo dua rau pitting thiab crevice corrosion cracking. Cov hlau muaj qhov ua tau zoo rau nitrate * thiab organic * corrosion, tab sis muaj kev tiv thaiv corrosion hauv sulfur * thiab ntsev *. 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 tseem muaj kev tiv thaiv corrosion zoo hauv dej, chav dej nrog rau chav dej, huab cua, carbon dioxide thiab sib tov.
