Cylinders manufactured in accordance with this part of EN ISO 9329 may have specified room temperature properties, specified low temperature toughness properties and specified elongation resistance values ​​at high temperatures, in accordance with the intended service.

For heat-treated pipes, a batch shall consist only of pipes of the same grade of steel, the same temperature, the same manufacturing process, and the same nominal outside diameter and wall thickness. These pipes are subjected to the same finishing treatment in a continuous furnace or heat treated at the same furnace charge in a batch type furnace.

Except where only maximums are specified, deviations are valid either above or below the stated limits of the range for the same element from different sample products from the same heat, but not both above and below.

Steels intended for the manufacture of pipes covered by this part of EN IS0 9329 are generally considered weldable. However, it must be taken into account that the behavior of steel during and after welding depends not only on the steel, but also on the conditions in which the weld is prepared and carried out, and the end use of the steel.
