F51 duplex stainless hlau pob valve yog ib hom pob valve uas nws cov khoom tseem ceeb, suav nrog lub cev nruab nrab, sab laug thiab sab xis lub cev, pob, thiab qia, yog forged siv ASTM A182 F51. Nws yog qhov tsim nyog rau siab - cov kav xa hluav taws xob thauj mus los hauv ib puag ncig nrog cov ntsiab lus chloride ion siab thiab cov ntsiab lus sulfide. Cov khoom siv hauv lub valve no yog austenitic-ferritic duplex stainless hlau, nrog rau qib Suav zoo sib xws ntawm 022Cr22Ni5Mo3N. Nws cov khoom tseem ceeb yog 21.0 ~ 23.0% Cr, 4.5 ~ 6.5% Ni, 2.5 ~ 3.5% Mo, thiab 0.08 ~ 0.20% N. Txhawm rau txhim kho nws txoj kev tiv thaiv kev nyuaj siab corrosion thiab pitting corrosion hauv chloride- nplua nuj acidic media, cov ntsiab lus nitrogen ntawm hom hlau no tsis ntev los no tau nce. Nws cov corrosion kuj yog nruab nrab ntawm 316 thiab super austenitic stainless hlau uas muaj 5 ~ 6% Mo, nrog rau pitting corrosion kuj sib npaug ntawm PREN 29 ~ 36. Nws tuaj yeem hloov 317L thiab 317LN, thiab lwm yam.
