ASTM A 193 B8V Class 1A Heat Treatments


  • All austenitic stainless steels shall receive a carbide solution treatment.
    Class 1A can apply to finished bolting components. 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.
