DIN 2391-2 Grade St 35 bright drawn soft
DIN 2391-2 Grade St 35 bright drawn soft introduction
Seamless precision steel tube made from St 35 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.
