ASTM A 193 B8RA Class 1C Heat Treatments

  • All austenitic stainless steels shall receive a carbide solution treatment.
    Finished bolting components shall be carbide solution treated after all rolling, forging, heading, and threading operations are complete. This designation does not apply to starting material such as bar. Components shall be heated from ambient temperature and held a sufficient time at a temperature at which the chromium carbide will go into solution and then shall be cooled at a rate sufficient to prevent the precipitation of the carbide. Class 1C can apply to finished bolting components.
