To meet the tensile requirements, the Brinell hardness shall be over 200 HBW (93 HRB).

Class 1 is solution treated. Class 1A is solution treated in the finished condition for corrosion resistance; heat treatment is critical due to physical property requirement. Class 2 is solution treated and strain hardened. Austenitic steels in the strain-hardened condition may not show uniform properties throughout the section particularly in sizes over ³⁄4 in. in diameter.
For sizes ³⁄4 in. in diameter and smaller, a maximum hardness of 241 HBW (100 HRB) is permitted.
For diameters 1¹⁄2 and over, center (core) properties may be lower than indicated by test reports which are based on values determined at ¹⁄2 radius.
