- flanges cut from plates/sheets,

- flanges manufactured by machining from rolled or forged sectional steel and bar steel,

- cast flanges made of cast steel.

They are made of ferritic, austenitic and austenitic-ferritic steels for the construction of pressure vessels which are operated at working temperatures and ambient temperatures down to -10 °C and up to the upper temperature limits specified in Clause 2 and the relevant AD 2000-Merkblätter for the starting materials.
