Tsis tas li ntawd, qhov corrosion kuj ntawm ASTM A335 P22 alloy steel yeeb nkab kuj zoo heev, thiab nws muaj peev xwm tswj tau nws cov kev ua tau zoo thiab kev pab lub neej ntev nyob rau hauv ib puag ncig hnyav.
Tom ntej no, cia peb kawm txog cov txheej txheem tsim khoom ntawmASTM A335 P22alloy steel yeeb nkab. Cov txheej txheem tsim khoom feem ntau suav nrog cov txuas tseem ceeb xws li smelting, dov thiab kho cua sov. Thaum lub sij hawm smelting txheej txheem, cov ntaub ntawv raw yog rhuab mus rau lub xeev molten thiab cov khoom tsim nyog alloy ntxiv kom tau txais cov tshuaj muaj pes tsawg leeg thiab cov qauv hlau. Thaum lub sij hawm dov txheej txheem, qhov tseeb qhov loj me, qhov zoo ntawm qhov chaw thiab cov khoom siv kho tshuab ntawm cov yeeb nkab steel yog ua kom ntseeg tau los ntawm kev tswj xyuas qhov tsis xws li dov kub, ceev thiab deformation. Thaum kawg, qhov sib txuas kho cua sov pab tshem tawm cov kev ntxhov siab nyob hauv cov yeeb nkab steel thiab txhim kho nws txoj kev ruaj khov thiab kav ntev.
Cov yam ntxwv ua haujlwm ntawmASTM A335 P22alloy steel yeeb nkab kuj yog ib qho ntawm cov laj thawj rau nws qhov chaw. Ua ntej tshaj plaws, cov yeeb nkab steel muaj lub zog siab thiab tawv, tuaj yeem tiv taus siab thiab cuam tshuam, thiab ua tau raws li qhov xav tau ntawm ntau yam kev ua haujlwm nyuaj. Thib ob, nws muaj kev tiv thaiv corrosion zoo heev thiab tuaj yeem tiv thaiv kev yaig ntawm ntau yam tshuaj lom neeg kom ntseeg tau tias kev ua haujlwm ruaj khov mus ntev. Tsis tas li ntawd, ASTM A335 P22 alloy steel yeeb nkab kuj tseem muaj qhov kub thiab txias tsis kam thiab tuaj yeem tswj cov khoom siv hluav taws xob ruaj khov thiab tshuaj lom neeg nyob rau hauv qhov kub thiab txias.
Nws yog qhov tseeb vim tias cov yam ntxwv ua tau zoo tshaj plaws uas ASTM A335 P22 alloy steel yeeb nkab tau siv dav hauv ntau qhov chaw. Hauv kev lag luam roj av thiab tshuaj lom neeg, cov yeeb nkab steel yog siv los tsim cov kav dej kub thiab kub siab thiab cov cuab yeej siv los xyuas kom muaj kev nyab xeeb thiab ruaj khov ntawm cov txheej txheem ntau lawm. Nyob rau hauv lub teb ntawm lub hwj chim,ASTM A335 P22alloy steel yeeb nkab yog dav siv nyob rau hauv cov cuab yeej tseem ceeb xws li boilers thiab superheaters, withstanding kub thiab siab siab chav thiab dej kub, muab kev ruaj ntseg guarantee rau lub hwj chim ntau lawm. Tsis tas li ntawd, hauv kev lag luam hauv kev lag luam nuclear, cov yeeb nkab steel kuj tseem ua lub luag haujlwm tseem ceeb hauv kev tsim cov kav dej thiab cov ntim hauv cov tshuab hluav taws xob nuclear kom ntseeg tau tias kev nyab xeeb ntawm kev siv hluav taws xob nuclear.
Ntxiv rau thaj chaw thov saum toj no,ASTM A335 P22alloy steel yeeb nkab kuj tuaj yeem kho raws li cov neeg siv khoom xav tau kom ua tau raws li cov kev cai siv hauv cov xwm txheej tshwj xeeb. Piv txwv li, los ntawm kev kho qhov tsis xws li phab ntsa thickness, txoj kab uas hla thiab ntev ntawm cov yeeb nkab steel, nws tuaj yeem ua tau raws li qhov xav tau ntawm cov haujlwm sib txawv.
