Austenitic steels usually have the highest corrosion resistance. They contain 16 to 26 percent chromium and up to 35 percent nickel, and they are not hardenable by heat treatment and are nonmagnetic. The most common type is the 18/8, or 304, grade, which contains 18 percent chromium and 8 percent nickel.
