Standards and other documents referred to

This standard is included in DIN Handbook 403 and 405. Specifies technical delivery conditions for seamless circular tubes made from high-temperature austenitic steel as specified in Table 1. Such tubes are intended primarily to be used in high-pressure applications where elevated temperatures and high mechanical stresses are involved (e.g. in the construction of pressure boilers, pressure vessel, pipelines, and in the chemical industry).
