254 SMO stainless hlau yog austenitic stainless hlau tsim rau qhov ua haujlwm siab tshaj plaws rau pitting thiab crevice corrosion. Nrog rau qib siab ntawm chromium, molybdenum, thiab nitrogen, 254SMO tshwj xeeb tshaj yog tsim rau cov tshuaj muaj kuab siab ntau qhov chaw xws li brackish dej seawater pulp mill bleach nroj tsuag thiab lwm cov txheej txheem chloride siab. 254SMO muaj chloride tsis kam zoo dua li ntawm Alloy 904L Alloy 20, Alloy 825 thiab Alloy 254SMO yog sib xws nrog cov hom austenitic stainless hlau. Nws feem ntau siv los hloov chaw nyob rau hauv cov khoom tseem ceeb ntawm kev tsim kho loj dua uas hom 316L lossis 317L tau ua tsis tiav los ntawm kev pitting, kev tawm tsam, los yog chloride kev nyuaj siab corrosion tawg. Hauv kev tsim kho tshiab, 254SMO tau pom nyob rau hauv ntau qhov tshwm sim los ua qhov thev naus laus zis kom zoo thiab ntau tus nqi qis dua rau cov khoom siv nickelbased alloys thiab titanium. 254SMO yog qhov muaj zog dua li cov qib austenitic, tab sis tseem muaj tus yam ntxwv ua tau zoo thiab muaj zog cuam tshuam. 254SMO yog ntaub yooj yim thiab welded.

Daim teb thov ntawm 254SMO:

254SMO alloy yog cov khoom siv ntau yam, tuaj yeem siv hauv ntau qhov chaw ua haujlwm:

Cov roj av, cov khoom siv roj av, xws li cov roj yeeb rau hauv cov khoom siv petrochemical.

Flue gas desulfurization unit fais fab nroj tsuag, qhov chaw tseem ceeb: nqus ntauwd, nplaim taws, lub qhov rooj muag khoom, sab hauv, tshuaj tua kab ntauwd thiab lwm yam.

Lub hiav txwv dej los yog kab ke, xws li kev siv hluav taws xob ua hluav taws xob nrog cov txheej txheem nyias nyias ua rau cov yeeb yaj kiab, ua kom dej txias hauv hiav txwv

cuab yeej siv, tsis hais txawm nyob hauv dej tej zaum yuav ntws tawm cuab yeej siv tau.

Qhov tsim nyog hauv kev lag luam, xws li cov khoom siv ntsev los yog ntsev tshem tawm.

Qhov tsim nyog hauv kev lag luam, xws li cov khoom siv ntsev los yog ntsev tshem tawm.

Thaum tshav kub kub ua kom sov, tshwj xeeb tshaj yog nyob hauv cov cua kub ua haujlwm ntawm chloride ion nyob hauv thaj chaw ua haujlwm.


Nrog kev dav thiab kev txawj ntse, Beall Kev Lag Luam Group yog ib qho ntawm cov ua s31254 254smo f44 tuam ntxhab thiab cov muag khoom. Peb muaj pua pua ntawm cov neeg ua haujlwm siab nyob ntawm koj cov kev pabcuam. Thov so assured kom tau txais tus nqi sib tw s31254 254smo f44 rau muag nrog peb.
