ASME SA203 steel yog nickel alloy steel phaj rau cov hlab ntsha siab, suav nrog tsib qib: A, B, D, E, thiab F (SA203GrA, SA203GrB, SA203GrC, SA203GrD, SA203GrE, SA203GrF).
SA203GrD steel muaj kev cuam tshuam zoo toughness thiab mechanical zog nyob rau hauv tsis tshua muaj kub tej yam kev mob, thiab feem ntau yog siv nyob rau hauv qis kub ib puag ncig ntawm -70 ~ -101 degree (lub xeev tempered yuav ncav cuag -107 degree). SA203GrD nickel alloy steel yog dav siv los tsim cov khoom siv hauv kev ua haujlwm ntawm kev sib cais cryogenic, cua sib cais, thiab cov roj liquefied cia. Nyob rau hauv xyoo tas los no, cov ntaub ntawv zoo li no tau siv rau hauv cov khoom siv kub qis xws li CO2 nqus cov yees, H2S concentration towers, thiab scrubbers hauv kev siv hluav taws xob hauv tsev. SA203GrD steel daim hlau feem ntau xa tuaj rau hauv cov txheej txheem, normalized ntxiv rau tempered lossis tempered xeev.
