This AD 2000-Merkblatt applies to hot- and cold-rolled plate, sheet and strip, seamless and welded tubes, forged, rolled and drawn bars and forgings, and bolts and nuts (mechanical fasteners) made of austenitic and austenitic-ferritic steels for the construction of pressure vessels operated at working temperatures and ambient temperatures down to −10 °C and up to the upper temperature limits specified in Clause 2. In principle, the steels are also suitable for use at temperatures lower than −10 °C. For working temperatures below −10 °C, AD 2000-Merkblatt W 10 is also applicable.

The basic requirements for the materials and material manufacturer are specified in AD 2000-Merkblatt W 0.
