DIN 17179 Grade WStE 285 normalized or normalized formed (+N)

DIN 17179 Grade WStE 285 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 from -20 to 400 degrees 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.

Equivalent material: DIN 1.0487, DIN P275NH, AFNOR P275NH, BS 224-400B, BS P275NH, AISI 290A, SAE 290A, EN P275NH, EN 1.0487, ISO P275NH, ASTM Grade 60
