Peb tau mob siab rau muab ntau yam S31803 duplex steel yeeb nkab thiab lub raj tso rau hauv cov khoom siv zoo. S31803 duplex stainless hlau cov kav dej thiab cov tub raj muaj cov yam ntxwv zoo ntws nrog lub zog siab dua thiab zoo dua tiv thaiv kev ntxhov siab corrosion tawg. Yog li ntawd, peb UNS S31803 duplex steel kav hlau tau muaj lub zog loj thiab muaj peev xwm tiv taus, ua ke nrog kev muaj peev xwm zoo dua qub los tiv thaiv pitting thiab tsim kev xeb. Cov txiaj ntsig zoo ntawm cov khoom yog nqa tawm hauv txhua yam ntaub ntawv raw khoom tau txais hauv Aleacion Tubos. Cov duplex steel kav tau siv rau qhov kub thiab siab thov kev siv. Peb tuaj yeem muab cov yas no rau hauv cov qauv sib txawv raws li cov neeg yuav tsum tau ua. Peb duplex thiab stainless hlau tubing tau yooj yim welded rau hauv lub kaw lus rau cov xaim-pov thawj sib koom tes.
S31803 duplex stainless hlau yog cov tshuaj tiv thaiv zoo rau ntau qhov kev siv qhov twg 300 series stainless hlau muaj qhov yooj yim rau chloride corrosion tawg. Kev nyuaj siab corrosion tawg tshwm sim thaum cov hlau stainless muaj kev ntxhov siab ntau ntau, thaum nyob hauv kev sib cuag nrog cov kev daws teeb meem uas muaj chlorides. Ua kom kub nce ntxiv kuj ua kom qhov muaj kev cuam tshuam ntawm cov hlau tsis tshua muaj zog txhawm rau txhim kho kev tawg. Kev sib xyaw ntawm chromium, molybdenum thiab nitrogen imparts 2205 qhov ua tau zoo rau chloride pitting thiab crevice corrosion. Lub siab ntawm chromium, molybdenum thiab cov ntsiab lus nitrogen ntawm 2205 muab zoo dua corrosion tsis kam mus rau cov hlau tsis xws luag xws li 316L thiab 317L hauv cov cheeb tsam feem ntau.
