C28000 tooj dag yog dab tsi?
C28000 yog ib qho + duplex zoo tib yam tooj dag nyob rau hauv American ASTM / UNS tus qauv txheej txheem, tseem hu ua 60/40 tooj dag (nrog cov ntsiab lus tooj liab ntawm 59.0% -63.0% thiab zinc raws li qhov seem). Nws nthuav tawm cov khoom kub zoo heev- ua haujlwm, sib npaug ntawm lub zog thiab plasticity, thiab nruab nrab corrosion kuj. Qhov no ua rau nws muaj ntau yam khoom siv tooj dag siv dav hauv kev tsim khoom, kav dej, thiab kev tsim kho. Qib suav suav yog H60.

Cov yam ntxwv ua
Kub-Kev Ua Haujlwm:Qhov kub zoo tshaj - ua haujlwm kub yog 680-780℃. Nws ua tau zoo heev - kub plasticity, tso cai rau ib zaug - dhau deformation mus txog 50-60%, ua rau nws haum rau kub dov, forging, thiab extrusion.Nco tseg:Qhov kub ntawm 500-600℃yuav tsum tau zam thaum ua haujlwm los tiv thaiv qhov nruab nrab - kub brittleness thiab tawg.
Txias-Kev Ua Haujlwm:Nws muaj qhov txias txias zoo - muaj peev xwm ua haujlwm, nrog qhov txo qis tshaj qhov txias ntawm li 50%. Ib qho nruab nrab annealing ntawm 420-460℃tom qab cua txias tuaj yeem rov ua kom nws cov yas zoo, ua rau nws tsim nyog rau stamping, dabtsi yog khoov, thiab cov txheej txheem txias rau cov txheej txheem nyuaj.
Machineability:Machinability yog nruab nrab (nyob ib ncig ntawm 70-80, nrog dawb - txiav tooj dag C36000 raws li 100 siv). Nws nyhav tsim cov chips txuas ntxiv, xav tau cov cuab yeej ntse thiab cov kev txiav tsim nyog.
Weldability:Brazing thiab roj-shielded vuam siv tau. Arc vuam feem ntau tsis pom zoo vim nws tuaj yeem ua rau tawg yooj yim intergranular. Ua ntej-vuam tu ntawm qhov chaw oxides thiab cov khoom paug yog qhov tseem ceeb, thiab cov khoom siv hluav taws xob yuav tsum tau tswj kom txo tau qhov tsis xws luag.
Corrosion Resistance:Nws muaj kev tiv thaiv zoo hauv huab cua qhuav, dej tshiab, thiab nruab nrab ntsev daws. Txawm li cas los xij, nws muaj kev cuam tshuam rau dezincification corrosion nyob rau hauv moist, sulfur-muaj cua thiab acidic media. Kev kho deg zoo li passivation lossis npib tsib xee plating tuaj yeem txhim kho corrosion kuj. Rau siab - kev siv kev ntxhov siab, kev ntxhov siab los ntawm 250-300℃yog qhov tsim nyog los tiv thaiv kev ntxhov siab corrosion.
