Scope: This standard specifies methods for reducing the susceptibility or degree of susceptibility to hydrogen embrittlement that may occur during surface finishing. . The heat treatment process specified in this standard can effectively reduce the susceptibility to hydrogen embrittlement. These heat treatment steps are performed after surface finishing, but before any secondary conversion coating steps. The stress relief heat treatment procedure used after the machining process but before surface finishing is specified in GB/T 19349. This standard does not apply to fasteners. NOTE: Heat treatment does not guarantee complete elimination of the harmful effects of hydrogen peroxide.
