Qhov ceev ntawm 1.4845 yog dab tsi?
Tus naj npawb 1.4845 yog hais txog qib ntawm stainless hlau (AISI 310S), tsis yog cov khoom siv nrog ib tus nqi ntom ntom; its density is consistently around 7.9 g/cm³ (or 7900 kg/m³), but slight variations exist (eg, 7.75 to 8.0 g/cm³), depending on the manufacturer and specific alloy composition.
Dab tsi yog qhov ntsuas kub siab tshaj plaws rau 1.4845 stainless hlau?
1.4845 stainless hlau (AISI 310) muaj kev ua tau zoo heev - qhov kub thiab txias, nrog rau qhov siab tshaj plaws kev pabcuam kub kub feem ntau nyob ib ncig ntawm 1050℃(1922℃F) hauv huab cua, txawm tias qhov kub siab tshaj plaws tuaj yeem ncav cuag 1100℃(2012℃F) rau lub sijhawm luv, nyob ntawm qhov chaw thiab cov ntsiab lus sulfur, muab kev tiv thaiv rau oxidation.
Puas yog 1.4845 stainless hlau sib nqus?
Tsis yog, 1.4845 stainless hlau (tseem hu ua AISI 310S) yog qhov tseem ceeb tsis yog- hlau nplaum vim nws cov qauv austenitic, muab siab heev - qhov kub thiab txias tsis kam, tab sis nws tuaj yeem ua tsis muaj zog hlau nplaum yog tias txias hnyav heev (xws li khoov lossis tsim).
Daim ntawv thov ntawm Qib 310/310S Stainless Hlau
Cov Ntawv Thov Qib 310/310S yog siv nyob rau hauv fluidised txaj combustors, kilns, radiant tubes, raj hangers rau roj av refining thiab chav boilers, thee gasifier internal Cheebtsam, lead pots, thermowells, refractory thauj tog rau nkoj bolts, burners thiab combustion chambers, cov khoom noj, cov khoom noj, Cov khoom siv ua haujlwm, cov qauv cryogenic.
Qhov txawv ntawm 1.4842 thiab 1.4825 yog dab tsi?
Ob leeg 310 thiab 310S yog 25Cr-20Ni siab chromium nickel austenitic stainless hlau. Qhov sib txawv tseem ceeb nyob rau hauv cov ntsiab lus carbon (310 Tsawg dua lossis sib npaug li 0.25%, 310S Tsawg dua lossis sib npaug li 0.08%). 310S tau txhim kho tau zoo siab -kub intergranular corrosion kuj thiab weldability vim nws cov yam ntxwv ntawm cov pa roj carbon tsawg, thiab yog qhov tsim nyog rau siab - qhov kub thiab txias yuav tsum muaj cov khoom siv furnace xws li cov khoom siv furnace. 310 muaj qhov kub thiab txias me ntsis hauv cov xwm txheej uas tsis yog vuam vim nws cov ntsiab lus carbon ntau dua. Ob leeg tuaj yeem pom cov oxidation zoo tshaj 1000 degree.
