ASTM A312 uns S31254 khoom yog dab tsi?
ASTM A312 UNS S31254 (tseem hu ua 254 SMO, 6Mo) yog lub siab -alloy super austenitic stainless hlau yeeb nkab uas muaj cov qib siab ntawm chromium, nickel, molybdenum, thiab nitrogen. Nws yog tsim tshwj xeeb los muab kev tiv thaiv corrosion zoo heev hauv chloride- thaj chaw nplua nuj (xws li dej hiav txwv, cov ntaub ntawv / ntawv mills, thiab cov chaw ua tshuaj), muab kev tiv thaiv zoo tshaj rau pitting corrosion, crevice corrosion, thiab kev ntxhov siab corrosion cracking piv rau cov pa steels.
