This European Standard specifies the technical delivery conditions in two test categories for seamless tubes of circular cross section made of austenitic (including creep resisting steel) and austenitic-ferritic stainless steel which are applied for pressure and corrosion resisting purposes at room temperature, at low temperatures or at elevated temperatures.
This standard also covers the classification and designation of steel grades, the manufacturing process, general requirements, inspection, sampling, test methods, marking, handling and packaging of seamless tubes.
