All tubes are furnished in heat-treated condition according to standard procedures. For seamless tubes, as an alternative to final heat treatment in continuous or batch-type furnaces, tubes may be individually quenched in water or rapidly cooled by other means immediately following hot forming while maintaining temperatures not less than the specified minimum solution treatment temperature.
