304 stainless hlau luj tshib hauv huab cua lossis tshuaj lom neeg corrosion nruab nrab tuaj yeem tiv thaiv corrosion ntawm chromium-nickel stainless hlau, 304 stainless hlau luj tshib Zoo corrosion kuj, tsis tas yuav mus los ntawm kev kho deg xws li xim txheej , tuaj yeem ua si zoo heev corrosion kuj ntawm stainless hlau, 304 yog ib tug universal stainless hlau, nws yog dav siv nyob rau hauv zus tau tej cov seamless steel hlab thiab yeeb fittings uas yuav tsum tau zoo kev kawm. Stainless hlau qib "304" (S30400) yog lub npe ntawm qib hauv American stainless hlau qauv, xws li ASTM tus qauv. Hauv cov qauv tsim tshiab Tuam Tshoj GB / T20878-2007 stainless hlau qib tus qauv, cov qib sib xws yog 30408/06Cr19Ni10 (qib dhau los yog 0Cr18Ni9). Qib no yog ib yam ntawm hom nto moo 18-8 Cr-Ni austenitic stainless hlau. Vim tias nws muaj cov yam ntxwv zoo heev thiab siv dav, nws cov khoom siv thiab kev siv nyiaj txog li 80 feem pua ntawm tag nrho cov austenitic stainless hlau.

Kev ua tau zoo ntawm 304 stainless hlau luj tshib: 304 stainless hlau luj tshib yog qhov siv ntau tshaj plaws chromium-nickel stainless hlau luj tshib hauv cov yeeb nkab fittings, nrog zoo corrosion kuj, kub tsis kam, tsis kub tsis kam thiab cov khoom siv kho tshuab. Corrosion tsis kam nyob rau hauv cov huab cua, txawm tias nws yog ib qho chaw ua lag luam lossis thaj chaw muaj kuab heev, nws yuav tsum tau muab ntxuav kom huv si lub sij hawm los tiv thaiv corrosion. Haum rau kev ua zaub mov, roj av, tshuaj cia thiab kev thauj mus los. Nws muaj kev ua haujlwm zoo thiab weldability. 304 stainless hlau luj tshib muaj zoo heev stainless corrosion kuj thiab zoo intergranular corrosion kuj. Nws muaj zog tiv thaiv corrosion rau oxidizing acids, xws li nitric acid hauv qab ntawm lub boiling point ntawm tsawg dua los yog sib npaug li 65 feem pua. Nws kuj muaj qhov zoo corrosion kuj rau alkali tov thiab feem ntau cov organic thiab inorganic acids. Nws muaj kev kub thiab txias zoo heev thiab kev ua haujlwm zoo. Nws tuaj yeem ua tiav thiab tsim phaj, raj, hlau, pluaj thiab ntau yam khoom, thiab tsim nyog rau kev ua kom txias taub hau, sib sib zog nqus nqus thiab nqus qhov nqus. Tsawg kub ua haujlwm zoo dua. Ntawm -180 degree C, lub zog, elongation, thiab contraction ntawm seem yog zoo. Txij li thaum tsis muaj qhov hloov pauv hloov kub, nws feem ntau siv rau qhov kub thiab txias. Nws muaj kev ua haujlwm zoo welding. Nws tuaj yeem welded los ntawm txoj kev vuam ib txwm, thiab kev kho cua sov tsis tas yuav tsum tau ua ntej thiab tom qab vuam. Lub kaum sab xis ntawm 304 stainless hlau luj tshib: 45 degree, 60 degree, 90 degree, 180 degree
