European Standard EN 10296-2,Welded Tubes(Chemical compositions)
BS EN 10296-2 is the material standard for stainless and heat-resisting steels
for circular welded tubes for mechanical and general engineering (ie not
pressure) purposes. Introduction This new standard was first published in December 2005 and replaces BS 6323-8:1982, which is now withdrawn.
Included in the standard are chemical compositions, delivery conditions and process route symbols, ambient temperature mechanical properties, some additional optional tests (leak testing, flattening, drift expansion, bend and non-destructive testing) and some dimensional and tolerance requirements.
Ferritic (7), austenitic (17), and austenitic-ferritic (duplex) (2) stainless steel grades and austenitic heat resisting grades (6) are included in the range of grades specified in this standard. Only the chemical composition of the stainless steels in the standard are listed in this article. As an alternative to scanning down the list try the 'find' facility on your keyboard, using the 'Ctrl' and 'F' keys together. Type in the term you are looking for in the dialog box that then appears.
The data given is not intended to replace that shown in individual standards to which reference should always be made. BS EN 10296-2 chemical composition tables Corrosion resistant steels
