1.0408 (DIN 2391-2 : 1994-09) 1.0408 DIN 2391-2 : 1994-09 DIN 2391-2 : 1994-09 replaced by DIN EN 10305-1 : 2003-02 Replaced Germany E255 ≤ 300 1)
1) Remark: Seamless precision steel tube made from St 45 is mainly used as construction element with special requirements in dimension accuracy, small wall thicknesses and good surface condition. The tubes are made in different grades (A and C). Grade C is valid for conduits. Grade A: for mechanical load without special grade requirement, without inspection certificate Grade C: for special requirements (testing after arrangement, e.g. bending, flanging, bulging a.o.) The weldability is given.
