Abstract

The hot rolling sheet production technology leaves behind in the sheet residual surface stress fields, which are due to the uneven strip cooling during rolling, the process of coiling, coil cooling and cold deformation during uncoiling. What concerns cold deformation during coil straightening, we expect that after exceeding the yield point in a surface layer on the tensile strained side, compressive residual stress remains there, and on the other, compressed side tensile residual stress. The influence of surface residual stress on properties of hot rolled steel KODUR E460 TS, KODUR E550 TS and KODUR E700 TS is investigated in this work.
