Cobalt-raws li alloys tsim los ntawm kev ntxiv cov ntsiab lus xws li lawv cov ntsiab lus chromalance, thiab corrosion industrial than than {}}}}} Muaj feem ntau hauv qab no Kev Sib Tw:
1. Kev faib tawm los ntawm kev siv thiab kev ua haujlwm
- Hnav-resistant cobalt-raws li alloys:
Sawv cev los ntawm stellite alloys, lawv muaj cov pa roj carbon monoxent siab (0 {}} 2% ~}}) Lawv feem ntau siv nyob rau hauv cov sij hawm nrog kev coj loj heev, xws li cav ntoo, thiab cov cuab yeej txiav.
- Kev kub-kub cobalt-raws li alloys:
Ntxiv cov ntsiab xws li chromium, npib tsib xee los tsim cov kev ua haujlwm ruaj khov thiab ua kom muaj kev sib zog ua ke ntawm 650), uas yog siv rau hauv cov dav hlau cav, thiab lwm yam
- Corrosion-resistant Cobalt-raws li alloys:
Nce cov ntsiab lus chromium thiab molybdenum cov ntsiab lus (xws li CR 20% ~ 30%, thiab ntau dua li Haynes 188 Alloy.
Tsuas yog cobalt-chromium-molybdenum (co-cr-mo) alloys, nrog kev sib koom ua ke rau hniav, kev cog hniav, thiab lwm yam}
{{02. Cov qhab nia yog suav nrog Stellite 6 thiab Stellite 6B
Raws li cov neeg xa khoom tsis yog-ferrous hlau nrog ntau tshaj 20 xyoo ntawm ntau lawm 20 xyoo ntawm kev tsim khoom thiab kev muag khoom tuaj yeem muab cov neeg siv khoom txawv teb chaws nrog cov khoom lag luam txawv teb chaws zoo xws liCobalt 6b puag ncig bar, Cobalt alloy 6 nozzle, Stellite 6 electrode, Stellite Alloy Pob Valve, thiabStellite homogenizer.

- Kev Ua Txawv Sib Txawv
-Qhov chaw thiab hnav tsis kam:
Stellite 6 muaj cov ntsiab lus carbon ntau dua, cov ntaub ntawv ntau dua, muaj chav muaj zog ntawm kev ntxhov siab ib puag ncig {}}
Stellite 6b muaj qhov qis dua qis dua (hrc 38-42 Cov ncauj lus tseem ceeb yog tseem zoo dua nyob rau hauv nruab nrab hauv nruab nrab, thiab nws txoj kev nruj me ntsis tau txhim kho.
-Txoj kev ua haujlwm thiab tawg tsis kam:
Cov ntsiab lus muaj roj carbon ntau ntawm stellite 6 ua rau nws muaj kev nruj me ntsis, thiab nws yooj yim tawg ua raws li kev cuam tshuam cov khoom; Stellite 6B txhim kho nws txoj kev nruj me ntsis los ntawm kev txo cov pa roj carbon (cuam tshuam rau kev ua kom rog (xws li cov khoom siv hluav taws xob tsis kam (roj hmab tsis kam) .
-Ua Kub Ua Tau Zoo:
Ob leeg tuaj yeem ua kom muaj kev ua tau zoo hauv qab 600 degree, tab sis me ntsis zoo dua kev faib tawm ntawm cov carbides hauv siab thiab zoo li 650 degree).
Tougness thiab tawg tsis kam:
Cov ntsiab lus muaj roj carbon ntau ntawm stellite 6 ua rau nws muaj kev nruj me ntsis, thiab nws yooj yim tawg ua raws li kev cuam tshuam cov khoom; Stellite 6B txhim kho nws txoj kev nruj me ntsis los ntawm kev txo cov pa roj carbon (cuam tshuam rau kev ua kom rog (xws li cov khoom siv hluav taws xob tsis kam (roj hmab tsis kam) .
- Qhov sib txawv hauv kev thov cov xwm txheej
Stellite 6: kev coj zoo, tsawg cuam tshuam ib puag ncig: excavator thoob cov hniav, cov pa dej siab
Stellite 6B: Cov ris Nruab Nrab Nruab Nrab, Kev Cuam Tshuam Ib Cheeb Tsam, nws yog qhov tsim nyog rau Weld tawg (xws li kev sib tsoo sab hauv (} {}
