1 Scope This International Standard specifies procedures for reducing susceptibility, or degree of susceptibility, to hydrogen embrittlement that can arise in surface finishing processes. The heat-treatment procedures for iron or steel specified in this International Standard have been shown to be effective in reducing the susceptibility to hydrogen embrittlement. These heat-treatment procedures are used after surface finishing, but prior to any secondary conversion-coating operation. Stress-relief heat-treatment procedures applied after fabrication, but prior to surface finishing, are specified in ISO 9587. This International Standard does not apply to fasteners.
NOTE The heat treatment does not guarantee complete freedom from the adverse effects of hydrogen embrittlement.
