DIN 17125 Grade StE 255 normalized or normalized formed (+N)
DIN 17125 Grade StE 255 normalized or normalized formed (+N) introduction
The fine grained steel is used acc. DIN 17178 : 1986-5 for welded steel tubes and acc. DIN 17179 : 1986-5 as seamless steel tubes for special purposes down to -20 °C.
Application:
pressure vessel construction, apparatus construction, pipelines, mechanical engineering, toolbuilding
Special requirements regarding processing have to be arranged (e.g. coatings). For welded tubes the calculation with the 100 % loads are possible for the seam area.
