The use of standard austenitic stainless steels like 304 and 316 is forbidden in this application. The best steels to use for this purpose are the high nickel austenitic steels such as the 6% Mo grades.Chemical Composition of Structural SteelsStructural steels, therefore, have carbon contents between 0.15 to 0.30 percent; if the carbon content goes much higher, the ductility will be too low, and for magnitudes less than 0.15 percent the strength will not be satisfactory. Manganese (Mn) Manganese appears in structural steel grades in amounts ranging from about 0.50 to 1.70 percent.
