Kev piav txog
304h Stainless Hlau Vuam Hlau yog cov vuam cov khoom siv ua los ntawm 304h stainless hlau raws li cov khoom siv hauv paus rau hauv qhov chaw kub. Nws cov neeg muaj zog tsim qauv zoo txhim kho qhov kev kub siab thiab lub zog ntawm cov weld. Nws qhov kev ua tau zoo sib npaug muaj zog thiab corrosion tsis kam, tab sis nws yog ib qho tseem ceeb rau kev ua kom zoo dua vuam ua kom tsis txhob muaj kev txhim kho corrosion.

Tshuaj Muaj Tshuaj
304h txhim kho lub zog siab los ntawm cov ntsiab lus carbon ntau ntxiv (0.04% rau 0.10%), thaum lwm cov ntsiab lus yog tib yam li 304.

Qhov sib txawv nrog lwm qib
304 vs . 304 h:Qhov sib txawv hauv cov ntsiab lus carbon (304h yog siab dua), 304H yog qhov tsim nyog dua rau cov chaw kub thiab xws li 525 degree). Corrosion tsis kam yog sib piv rau 304, tab sis tom qab vuam yuav yog vim carbide nag lossis nag los txo qhov corrosion, kev kho cov teeb meem kev daws teeb meem.
304l vs . 304 h:304l yog cov pa roj ultra (tsawg dua los yog sib npaug 0.03%), tsom mus rau ntawm cov chaw sib txuam; 304H yog lub zog kub siab, lub zog kub yog qhov zoo heev, 500℃hauv qab cov plawg tau zoo dua li 304L.
Xaiv ceeb toom:
Vuam Seam thiab cov khoom siv puag ncig kev sib txuam, txo qhov kev pheej hmoo ntawm kev ntxhov siab tawg ntawm dissimilar hlau vuam.
Chloride ion ib puag ncig xav tau kom phim 316H Vuam Hlau (muaj MO).
Cov huab cua ib txwm muaj los yog tsis muaj zog corrosion corrosion tuaj yeem siv 304H kom tsis txhob muaj kev cuam tshuam ntau dhau.

Cov Khoom Siv Petrochemical
- Kev hloov cua sov kub thiab reactors:Nyob rau hauv cov roj ua kom zoo dua, nws yog siv los ua kom sov pa hluav taws xob thiab cua sov kom tiv thaiv cov txheej txheem roj crude.
- Chav piping thiab boiler Cheebtsam:Siv ua vuam cov khoom rau boiler SuperHeater thiab kev khiav ceev, kom muaj kev ruaj ntseg ntawm lub pa hluav taws xob.
- Kev tso tsheb hlau luam thiab cov hlab ntsha siab:Welded cia ntawm corrosive media (xws li gases acid) ntim) ntim khoom) ntim, siv cov ntsiab lus chromium-npib tsib xee tawm los tiv thaiv media yaig.
Kev lag luam fais fab
- Kev kub-ntsuas kub rau cov fais fab nroj tsuag:Siv nyob rau hauv Chav xa dej thiab Flue Gas desulfurization tshuab ntawm Coal-phov zog hluav taws xob nroj tsuag, tiv taus cov roj hluav taws xob ntau-hluav taws kub.
- Nuclear Zog Khoom:Nyob rau hauv lub nuclear reactor cua txias zog, welded siab resistant siab piping, kom tau raws li kev thov kev pabcuam ntev hauv hluav taws xob.
