This Standard is included in DIN Handbook 403 E. Applies to seamless circular tubes made from carbon and alloy steels with low temperature toughness, as listed in Table 1, for low temperature applications. These tubes are predominantly used in the construction of chemical plant, vessels, pipework and for general mechanical engineering purposes.
