235B can basically no longer be used for pressure-bearing components. Between 245R and 345R, 245R is the preferred choice, especially in cases of hydrogen sulfide stress corrosion.

235B is used for pipelines at normal temperatures, while 245R and 345R are used for pressure vessels at normal temperatures

Use 235B for the structure, and those two for containers
