Zoo heev Oxidation thiab Reduction Resistance
Cov ntsiab lus chromium siab (20.0-22.5%) ua kom muaj qhov ntom ntom thiab ruaj khov Cr₂O₃ zaj duab xis passivation hauv oxidizing media (xws li nitric acid, sulfuric acid uas muaj Fe³⁺/Cu²⁺, moist chlorine gas). Cov ntsiab lus siab molybdenum (12.5-14.5%) thiab tungsten ntxiv (2.5-3.5%) muab cov khoom zoo tshaj plaws corrosion kuj hauv kev txo cov xov xwm (xws li hydrochloric acid, dilute sulfuric acid). Piv rau cov nickel-raws li zoo sib xws xws li C-276, C-4, thiab 625, C-22 muaj qhov zoo dua thiab muaj kev tiv thaiv corrosion ntau dua, ua rau nws los daws cov kev pabcuam nyuaj xws li muaj zog oxidizing kom txo qis ib puag ncig. Nws yog ib qho zoo tagnrho xaiv cov khoom siv rau ntau yam corrosive media.
Exceptional Resistance rau Pitting, Crevice Corrosion, thiab Stress Corrosion Cracking
Lub synergistic nyhuv ntawm siab chromium, molybdenum, thiab tungsten cov ntsiab lus ua rau pitting kuj sib npaug (PREN=% Cr + 3.3 ×% Mo + 16 ×% N) ntawm ntau dua 65 rau C-22, muab kev tiv thaiv zoo rau pitting thiab crevice corrosion hauv . chloride{15} ib puag ncig. Raws li ASTM G48 tus qauv (6% FeCl₃ kev tshuaj ntsuam xyuas), qhov tseem ceeb pitting kub (CPT) ntawm C-22 tshaj 150 degree, thiab qhov tseem ceeb crevice corrosion kub (CCT) yog kwv yees li 80 degree, ho outperforming 316L stainless hlau thiab feem ntau zoo sib xws alloys. Tsis tas li ntawd, C-22 nthuav tawm kev tiv thaiv rau chloride-induced stress corrosion cracking, ua raws li NACE MR0175 / ISO 15156-3 cov qauv, ua rau nws haum rau hnyav hnyav xws li acidic gas teb.
Superior Weldability thiab Thermal Stability
Ultra- cov pa roj carbon tsawg ( Tsawg dua lossis sib npaug li 0.015%) thiab cov ntsiab lus tsis tshua muaj silicon nruj me ntsis txwv cov impurities xws li hlau thiab cobalt, tiv thaiv kev tsim cov teeb meem intermetallic theem (piv txwv li, σ theem) thaum kub ua hauj lwm thiab vuam. Txawm nyob rau hauv tshav kub- cuam tshuam cheeb tsam tom qab vuam, nws cov corrosion kuj tseem yuav luag tsis cuam tshuam. Tom qab-weld solution annealing tsis tas yuav tsum tau, tso cai siv ncaj qha rau hauv cov kev pabcuam corrosive, ua rau cov txheej txheem tsim khoom yooj yim heev.
Zoo Formability thiab Weldability
Nws tuaj yeem tsim los ntawm cov txheej txheem ua haujlwm kub thiab txias. Qhov zoo tshaj plaws txias formability, vim zoo ductility, cia yooj yim txias dov thiab txias txias. Qhov pom zoo ua haujlwm kub kub yog 950-1200℃. Nws muaj qhov zoo weldability (GTAW / TIG, GMAW / MIG, SMAW, thiab lwm yam) thiab pom zoo kom siv ERNiCrMo-10 muab tub lim (AWS A5.14 tus qauv). Interpass kub yuav tsum tau tswj ntawm tsawg dua los yog sib npaug rau 100℃. Post-weld tov annealing tsis tas yuav tsum tau, thiab nws tuaj yeem siv ncaj qha rau hauv kev pabcuam corrosive.
