ASTM F738 Class A2-70 S34700 Heat Treatments

  • Condition CW: annealed by heating to 1040 (+/-30°C), at which time the chromium carbide will go into solution. The fasteners shall be held for a sufficient time and then cold-worked to develop the specified mechanical properties. Products with nominal thread diameters larger than M20 may be hot-worked and solution annealed
