ASTM A240 Alloy 321/321H Austenitic Stainless Steel yog titanium-stabilized hlau uas muaj qhov kub thiab txias thiab corrosion kuj, tshwj xeeb tshaj yog zoo tiv thaiv intergranular corrosion tom qab vuam. Ob cov ntaub ntawv no tau siv dav hauv kev siv petrochemical, aerospace thiab tshav kub exchanger daim ntawv thov. Lawv kuj muaj zoo weldability thiab formability, uas ua rau lawv ua thiab installation yooj yim dua.
Raws li ib tug ua stainless hlau daim ntawv chaw tsim tshuaj paus thiab tsum nrog tshaj 18 xyoo ntawm export kev thiab muaj nyob rau hauv ntau tshaj 80 lub teb chaws, GNEE tsim ASTM A240 Qib 321H steel nplooj ntawv uas yuav siv tau nyob rau hauv qhov kub thiab txias ib puag ncig, withstanding kub txog li 816 degrees Celsius. 321 thiab 321H stainless hlau los xij yog kub-tiv taus, titanium-stabilized austenitic alloys uas ua tau raws li ASTM A240 tus qauv, muab kev tiv thaiv zoo rau qhov kub thiab txias. 321H yog cov pa roj carbon ntau dua ntawm 321, haum rau qhov kub thiab txias ib puag ncig thiab feem ntau siv hauv oxidizing tej yam kev mob hauv qab 800 degrees. 321H stainless hlau los xij yog siv rau hauv kev lag luam khoom noj khoom haus thiab kev tsim cov tank cia hauv cov nroj tsuag tshuaj. Cov khoom siv no kuj siv rau hauv kev lag luam tsheb thauj mus los.

ASTM Alloy A240 321 vs. 321H: Qhov txawv
Qhov sib txawv tseem ceeb ntawm ob qhov lus dag hauv lawv cov ntsiab lus carbon: alloy 321 muaj cov qauv carbon cov ntsiab lus (tsawg dua lossis sib npaug li 0.08%), thaum 321H (0.04-0.10%) muaj kev tiv thaiv ntau dua rau kev nkag thiab haum rau qhov kub siab dua. Ob lub alloys muaj nyob rau hauv daim ntawv kub dov.
Peb muab: Tshuag ntau thiab tsawg ntawm daim ntawv thiab thaiv, Tshuag ntev ntawm puag ncig tuav, kev cai daim ntawv thiab thaiv, kev cai puag ncig tuav, txias sib sau ntawm daim ntawv, thaiv thiab puag ncig tuav, thiab lwm yam tsim nyog kev pab cuam. Rau cov lus nug, nyem qhov txuas hauv qab no los tiv tauj peb.
Chaw tsim tshuaj paus ntawm cov ntawv zoo raws li ASTM A240 Hom 904L tus qauv
Tag nrho cov nplooj ntawv tau txais kev kho mob stripping thiab passivation los tsim ib qho kev tiv thaiv zaj duab xis, yog 100% pom kev soj ntsuam xyuas kom tsis muaj khawb, qhov thiab lwm yam tsis xws luag, thiab xyuas los ntawm cov cuab yeej cuab tam sim kom ntseeg tau tias kev ua haujlwm.
Kev ntim khoom zoo tshaj plaws thiab xa khoom los ntawm GNEE
Ntim: Txhua daim ntawv los yog coil yog qhwv hauv ntawv tsis muaj dej, npog nrog yas zaj duab xis thiab fastened nrog steel strapping. Cov txheej txheej sab nrauv yog tiv thaiv los ntawm pallets lossis ntoo thawv kom muaj kev nyab xeeb thaum thauj mus los thoob ntiaj teb.
Labeling: Txhua pob suav nrog rau tus naj npawb ntawm qhov cub, qib, qhov ntev thiab cov ntaub ntawv txheem.
Lub sij hawm xa tuaj: Feem ntau 7-15 hnub ua haujlwm tom qab tau txais cov nyiaj them ua ntej.
Shipping txoj kev: Kev thauj mus los hauv hiav txwv (tag nrho lub thawv / ib nrab load), huab cua thauj lossis xa khoom xa tuaj, raws li cov neeg siv khoom xav tau.
