ASTM A276 UNS S31400 Round Bar Chaw tsim tshuaj paus
GNEE muaj ntau tshaj 18 xyoo ntawm kev tsim khoom thiab xa tawm cov khoom tshwj xeeb stainless hlau, nrog rau cov khoom lag luam xa tawm hauv ntau tshaj 50 lub teb chaws thoob ntiaj teb. Peb muab cov khoom xa tuaj ib txhij rau ob qho kev txiav txim ntau thiab sim txiav txim ntawm S31400 round bar qauv. Peb cov khoom lag luam ntawm txoj kab uas hla npog los ntawm Φ6mm mus rau Φ350mm, thiab peb txhawb kev txiav rau txhua qhov ntev ntawm 1m thiab 12m. Peb muab plaub qhov sib txawv ntawm qhov tiav: kub dov dub, dawb pickled, txias kos ci thiab precision tig / peeled; tag nrho lawv muab nyob rau hauv tus txheej txheem solubilization annealed mob.
ASTM A276 314 stainless hlau tuav peb muab tuaj yeem tiv taus qhov kub thiab txias mus txog 1150℃nyob rau hauv oxidizing tej yam kev mob, thiab mus txog 1050℃rau kev pab cuam sib tshuam. Ntawm qhov kub thiab txias ntawm 1000℃rau 1000 teev, lub thickness ntawm oxidation txheej tseem qis dua 50 μm, thaum nyob rau hauv tib yam kev mob, 310S qib siab tshaj 100 μm. Qhov no ua kom muaj kev tiv thaiv siab rau scaling thiab tev nyob rau hauv thermal cycling tej yam kev mob. Tsis tas li ntawd, nws ua tiav lub neej creep rupture (nkag) uas tshaj 3000 teev nyob rau hauv ib qho kev ntxhov siab ntawm 100 MPa ntawm 600 degrees, ua rau nws tshwj xeeb tshaj yog haum rau tshav kub-resistant thiab load-bearing structural Cheebtsam, xws li tshav kub kho qhov cub grate, incinerator yam ntxwv qhov chaw thiab high-temperature petrochemical kev txhawb nqa.

Muab khi rau hauv bundles:Haum rau nruab nrab mus rau qhov loj txoj kab uas hla kub dov (dub) tuav los yog round steels nrog cov txheej txheem saum npoo tiav. Qhov hnyav ntawm pob khoom feem ntau khaws cia nruab nrab ntawm 1 thiab 3 metric tons los pab txhawb nqa thiab tshem tawm siv forklifts lossis cranes.
Braided npuag hnab / Stretch zaj duab xis (Xim):Nws muaj wrapping steel pob nrog ib txheej txheej ntawm woven polypropylene ntaub los yog stretchable yas zaj duab xis.
Ntoo Boxs / Huacales:Siv rau hauv hiav txwv export, txias drawn / ci tuav los yog me me txoj kab uas hla round steels nquag khoov. Txoj kev no tiv thaiv cov khoom tiv thaiv kev cuam tshuam thiab khoov deformations.
FAQ
Puas yog qib S31400 yooj yim rau vuam?
Soldering tuaj yeem ua tiav, tab sis ua haujlwm ceev faj. Feem ntau, stick arc vuam (SMAW) los yog TIG/MIG welding yog siv.
Pom zoo input khoom:Siv ER310 lossis ER314 vuam hlau uas phim cov hlau hauv paus muaj pes tsawg leeg.
Qhov siab tshaj plaws ua haujlwm kub rau SS 314 yog dab tsi?
Nyob rau hauv ib qho chaw oxidizing, qhov siab tshaj plaws kev pabcuam kub rau S31400 yog 1150 degrees (2100 degrees F). Nws kuj tseem tswj tau qhov kev ua tau zoo nyob rau hauv cov cua kub tsis sib xws, ua tau zoo tshaj 300 series stainless hlau.
