This standard specifies technical delivery conditions for cold finished seamless precision steel tubes of the dimensions listed in DIN 2391 Part 1, which are made from the steel grades listed in clause 4.
Such tubes are mainly used where accuracy to size and, possibly, a small wall thickness, a particular surface condition and specific mechanical properties are required.
