Super 304H Stainless Hlau Yeeb Nkab yog tsim los ntawm cov khoom siv Super 304H. Piv rau cov hlau tsis zoo tib yam, 304H tuaj yeem tiv taus qhov kub thiab txias ntawm 600-650℃thiab ua haujlwm ruaj khov ntawm cov cua kub siab tshaj 22.1 MPa.
Super304H yog ib qho kev lag luam 18-8 austenitic cua sov-resistant stainless hlau tsim raws li TP304H hlau. Los ntawm kev sib koom ua ke 3% Cu thiab 0.4% Nb, nws ua tiav qhov tshwj xeeb siab creep zog los ntawm kev sib xyaw ua ke ntawm cov qauv nplua-grained thiab nag lossis daus ntxiv los ntawm cov qib tooj liab zoo.
Nws cov corrosion kuj yog superior rau ntawm TP304H tab sis me ntsis qis dua li ntawm TP347H, thaum nws susceptibility rau vuam kub tawg yog qis dua li ntawm TP347H. Nws yog feem ntau yog siv rau superheater thiab reheater tubes qhov twg cov roj flue - sab phab ntsa kub tsis tshaj 705℃.
Customized Services
- TORICH muaj kev tsim khoom rau cov khoom tsis yog - tus qauv specifications, npog ib txoj kab uas hla ntawm 5mm mus rau 420mm thiab tej phab ntsa thickness nyob rau hauv qhov ntau ntawm 0.5mm mus rau 55mm.

Cov qhab nia xaiv tau
- TP347HFG (zoo nplej) qhia tau zoo dua creep tsis kam tshaj TP304H. Nws yog siv nyob rau hauv siab -kub cov kav dej thiab superheaters.
- TP310H tuav cov oxidation zoo heev ntawm qhov kub txog li 1050℃thiab tuaj yeem siv rau hauv cov kav dej kub thiab siab - kub exchangers.
- Piv rau Super304H, HR3C (UNS S31042) muaj ntau dua Cr thiab Nb cov ntsiab lus, uas ua rau muaj zog creep rupture thiab oxidation tsis kam.
thaj chaw thov
ASTM A213 Super 304H stainless hlau raj tau dav siv hauv cov haujlwm hauv qab no:
- Ultra-Supercritical (USC) Fais Fab Boilers: Siab- qhov kub thiab txias seem tube vaj huam sib luag rau uperheaters thiab reheaters.
- Advanced Ultra-Supercritical (A-USC) Units: Nruab nrab- mus rau- qhov kub thiab txias seem superheaters thiab reheaters.
- Heat Recovery Steam Generators (HRSG): High -kub kub exchanger tube bundles nyob rau hauv roj-steam ua ke lub voj voog lub zog tsim units.
- Kev Lag Luam Tshuaj thiab Petrochemical Kev Lag Luam: Cov raj cua sov hloov pauv rau siab - kub thiab siab - kev siv siab, xws li siab - kub exchangers, tawg rauv tubes, thiab hloov cov raj rauv.
- Pov tseg-rau-Cov nroj tsuag hluav taws xob: Superheater thiab reheater tube bundles rau incinerators.

FAQ
Q: Dab tsi yog qhov txawv ntawm Super 304H thiab tus qauv 304H stainless hlau tubing?
A: Super 304H yog ib qho kev txhim kho ntawm TP304H, muaj qhov sib ntxiv ntawm 3% tooj liab (Cu) thiab 0.4% niobium (Nb). Ua tsaug rau nws cov qauv zoo -cov qauv nplej thiab cov nag lossis daus ntxiv dag zog ntawm cov qib tooj liab zoo, nws ua tiav lub zog siab heev; tshwj xeeb, nws tso cai rau kev ntxhov siab hauv 600-650℃qhov kub thiab txias yog 30% siab dua li ntawm TP304H.
Q: Dab tsi yuav tsum tau ceev faj thaum vuam Super 304H?
A: Super 304H pom zoo weldability. Nws raug nquahu kom ntiav GTAW (Gas Tungsten Arc Vuam) lossis SMAW (Shielded Hlau Arc Vuam) cov txheej txheem, siv cov khoom siv vuam sib xws xws li YT-304H lossis #T-304H.
Q: Muab piv rau HR3C, vim li cas Super 304H thiaj li pom zoo siv rau hauv cov pa siab - qhov kub thiab txias ntawm ultra-supercritical boilers?
A: Thaum muab piv rau ob, Super 304H muab cov nqi zoo tshaj -kev ua tau zoo, nrog rau cov nqi khoom uas yog 20% mus rau 30% qis dua li ntawm HR3C, ntxiv rau muab kev ua haujlwm zoo dua thiab kev ua haujlwm vuam. Qhov zoo ntawm HR3C dhau los ua qhov tseem ceeb tshaj tawm tsuas yog nyob rau hauv siab heev - qhov kub thiab txias ua haujlwm ( Ntau dua lossis sib npaug li 650℃).
