ASTM A269 UNS S31254 steel yeeb nkab yog super austenitic stainless hlau yeeb nkab. UNS S31254 tseem hu ua 254SMO lossis 1.4547 stainless hlau. Nws cov yam ntxwv yog tias nws cov pitting kuj sib npaug tus lej (PREN) yog txhim kho los ntawm kev nce cov ntsiab lus molybdenum (txog 6%), ua rau nws qhov kev ua tau zoo ze rau super duplex stainless hlau.
254SMO stainless hlau puag ncig yeeb nkab muaj kev tiv thaiv corrosion siab heev, tshwj xeeb tshaj yog rau chloride thiab seawater corrosion. ASTM A269 UNS S31254 stainless hlau yeeb nkab yog dav siv nyob rau hauv ntau qhov chaw uas yuav tsum tau muaj corrosion kuj.
Nws yuav tsum tau muab sau tseg tias S31254 steel yeeb nkab yog ib tug tag nrho austenitic ib-theem qauv thiab yog heev rhiab heev rau vuam kub tawg. Yog li ntawd, nws yog ib qho tsim nyog los xaiv cov khoom siv qis S thiab P vuam thaum lub sij hawm vuam, xws li ERNiCrMo-3 vuam hlau thiab ENiCrMo-3 vuam pas nrig.
