Corrosion Kuj
1.4541
Oxidation tsis kam: Zoo heev hauv oxidizing ib puag ncig (piv txwv li chav, cov roj sib xyaw) txog li 900 degrees.
Kev txwv: Muaj peev xwm ua rau pitting corrosion hauv chloride ib puag ncig (piv txwv li dej hiav txwv) vim qhov tsis muaj Molybdenum.
1.4571
Chloride tsis kam: Kev sib xyaw ntawm molybdenum thiab titanium muab kev tiv thaiv zoo heev rau pitting corrosion, kev nyuaj siab tawg thiab intergranular corroside hauv chloride hauv chloride hauv chloride hauv chloride hauv chloride hauv chloride hauv chloride hauv chloride hauv chloride nyob rau chloride-nplua nuj xov xwm.
Kub Ceev: Tiv taus oxidation nce mus txog 870℃thiab ua haujlwm zoo hauv cov txheej txheem tshuaj lom neeg (piv txwv li cov kua qaub, alkalis).
Weldability thiab ua tau
1.4541
Vuam: Weldable yam tsis muaj teeb meem siv cov qauv txheem (piv txwv li tus qauv, Mig) tsis muaj kev kho cua sov ua ntej, ua tsaug rau cov khoom ruaj khov.
Ntaub: Yuav tsum tau cov cuab yeej ntse vim yog ib qho kev ua haujlwm hnyav ua haujlwm.
1.4571
Vuam: Zoo heev Veldability nrog tsawg kev pheej hmoo ntawm intergranular corrosion; Tau tshaj 316L lossis 316ti cov chaw ua haujlwm.
Ntaub: Zoo ib yam li 1.4541 tab sis me ntsis ntau dua vim yog molybdenum cov ntsiab lus.
Cov Ntawv Thov
