Hydrogen Embrittlement Relief

According to ASTM Standards, all electroplated parts having a tensile strength of 1200 MPa (174,045.24 psi) or higher must be baked at a minimum of 190ºC for 3 hours or more within 4 hours after electroplating to provide hydrogen embrittlement relief. According to NAS 514, the material used for making the screws must be heat treated to 125 - 145 KSI. This is equivalent to 861.84 MPa and 999.74 MPa respectively. Likewise NAS 517 requires that the material be heat treated to 160 - 180 KSI. This is equivalent to 1103MPa and 1241.06 MPa. Therefore all NAS 517 screws must be baked for 3 hours thus increasing the cost of the screws.
