Stellite alloys feem ntau yog cobalt nrog ntxiv ntawm Cr, C, W, thiab / lossis Mo. Lawv tiv taus cavitation, corrosion, yaig, abrasion, thiab galling.Qhov qis carbon allovs feem ntau pom zoo rau cavitation, zawv zawg hnav, lossis nruab nrab gallina.Cov pa roj carbon ntau dua feem ntau yog xaiv rau kev puas tsuaj, hnyav hnyav, lossis qis qis qis Stellite 6 yog peb cov hlau nrov tshaj plaws vim nws muab qhov sib npaug zoo ntawm tag nrho cov khoom no.
Cov Stellite alloys khaws lawv cov khoom ntawm qhov kub thiab txias uas lawv kuj muaj oxidation zoo heev.Lawv feem ntau yog siv nyob rau hauv qhov kub ntawm 315-600 ° C (600-1112 F).Lawv tuaj yeem ua tiav rau qhov tshwj xeeb ntawm qhov chaw tiav nrog qhov sib txhuam qis kom muab cov zawv zawg zoo.
Alloy | Kev sib xyaw | Hardness HRC | Melting ntau ℃ | Tej kev siv |
Stellite 6 | C: 1 Cr: 27 W: 5 Co: Bal | 43 | 1280-1390 Ib | Cov tawv tawv tawv-resistant alloy dav siv rau kev ua haujlwm zoo txhua yam.Tsis tshua muaj siab tawg tshaj Stellite" 12 n ntau txheej, tab sis ntau hnav resistant dua Stellite" 21 ir puas thiab hlau rau hlau tej yam kev mob.Kev cuam tshuam zoo.Kev cuam tshuam zoo.Valve rooj thiab rooj vag: ump ncej thiab bearings.erosion shields thiab rollina khub niam txiv.Feem ntau siv tus kheej-mated.Nws tuaj yeem tig nrog cov cuab yeej carbide.Kuj muaj xws li pas nrig, electrode thiab hlau. |
Stellite 6B | C: 1 Cr: 30 W: 4.5 Co: Bal | 45 | 1280-1390 Ib | |
Stellite 12 | C:1.8 Cr: 30 W:9 Co :Ba | 47 | 1280-1315 : kuv | Cov khoom nruab nrab ntawm cov Stellite "1 thiab Stellite" 6.Ntau qhov kev puas tsuaj ntau dua li Stellite" 6, tab sis stil zoo cuam tshuam tsis kam, dav siv los ua cov ntug hauv textile, ntoo thiab plastics industries thiab rau bearinas.Kuj muaj raws li pas nrig, electrode thiab hlau. . |
Feem ntau siv cov cuab yeej cemented carbide los ua 6B, thiab qhov tseeb ntawm qhov chaw yog 200-300RMS.Cov cuab yeej siv hlau yuav tsum siv 5 ° (0.9rad.) lub kaum sab xis tsis zoo thiab 30 ° (0.52Rad) lossis 45 ° (0.79rad) lub kaum sab xis.6B alloy tsis haum rau high-speed tapping thiab EDM ua yog siv.Txhawm rau txhim kho qhov chaw tiav, kev sib tsoo tuaj yeem siv kom ua tiav qhov siab.Tsis tuaj yeem quenched tom qab qhuav sib tsoo, txwv tsis pub nws yuav cuam tshuam rau cov tsos
Stellite tuaj yeem siv los tsim cov khoom siv valve, twj tso kua mis, lub cav cav los tiv thaiv corrosion, kub kub bearings, valve stems, khoom noj khoom haus, koob li qub, kub extrusion pwm, sib sau abrasives, thiab lwm yam.
