Abstract
Mechanical properties, fatigue resistance included, are analyzed for a low carbon Corten type steel sheet with improved corrosion resistance. The mechanisms of atmospheric corrosion is analyzed for low alloyed steel and compared to that of Corten type steel. The influence of two to five years exposition to atmospheric corrosion is shown. Statistics on mechanical properties are given for 2 to 6 mm sheet. Fatigue properties were tested by bending flat test pieces. The ratio sCo/Rm was compared before and after exposition to atmospheric corrosion. Properties of cold-rolled steel after annealing process and subsequent smoothing are given. Efficient improvements in the rolling production technology are possible. The change in properties by atmospheric corrosion are valuable data for users.
