ASME SA-193 Grade B8T Class 2 Heat Treatments

Material shall be carbide solution treated by heating from ambient temperature and holding a sufficient time at a temperature at which the chromium carbide will go into solution and then cooling at a rate sufficient to prevent the precipitation of the carbide.
Following this treatment the material shall then be strain hardened to achieve the required properties.
