304 / 304L Stainless Hlau Seamless Tubing
Khoom Taw Qhia
Alloys 304 (S30400) thiab 304L (S30403) stainless hlau yog variations ntawm 18 feem pua chromium - 8 feem pua nickel austenitic alloy, feem ntau paub thiab nquag siv alloy nyob rau hauv stainless hlau tsev neeg. 304 / L stainless hlau muaj cov khoom zoo heev. Nws cov malleability tso cai rau nws yooj yim tsim rau flaring, dabtsi yog khoov thiab coiling. Zoo machinability thiab cov ntsiab lus tsis muaj leej faj txhawb kev weldability zoo heev hauv daim ntawv thov xav tau.
Lub zog siab, zoo heev corrosion kuj thiab cov ntsiab lus carbon tsawg ua rau Alloy 304 thiab 304L Stainless Steels pab tau rau cov ntawv thov uas yuav tsum tau vuam. Siv xws li architectural moldings thiab trim, welded Chemical Chemical, textile, ntawv, tshuaj thiab tshuaj kev lag luam ua khoom siv.
Lwm qhov zoo yog nws cov kev tiv thaiv oxidation, zoo heev formability, yooj yim ntawm fabrication thiab tu, zoo heev lub zog rau qhov hnyav piv thiab zoo toughness ntawm cryogenic kub Rau qhov hnyav corrosive ib puag ncig, cov ntsiab lus qis ntawm Hom 304L yog qhov nyiam vim tias nws muaj kev tiv thaiv ntau dua rau intergranular corrosion.
Hom 304L stainless hlau yog ib qho ntxiv-tsawg carbon version ntawm 304 steelhlau alloy. Cov ntsiab lus ntawm cov pa roj carbon qis hauv 304L minimizes deleterious los yog teeb meem carbide nag lossis daus los ntawm vuam. 304L tuaj yeem, yog li ntawd, siv "raws li welded" nyob rau hauv ib puag ncig corrosion hnyav, thiab nws tshem tawm qhov xav tau ntawm annealing.
Qib no muaj cov khoom siv kho tshuab qis dua li tus qauv 304 qib, tab sis tseem siv dav ua tsaug rau nws cov khoom siv ntau yam. Zoo li Hom 304 stainless hlau, feem ntau yog siv hauv npias-brewing thiab wine-making, tab sis kuj rau lub hom phiaj tshaj li kev lag luam khoom noj xws li hauv cov ntim tshuaj, mining, thiab kev tsim kho. Nws yog qhov zoo tagnrho rau siv hauv cov khoom hlau xws li txiv ntoo thiab bolts uas raug dej ntsev.
