Hot Rolled Steel Sheet Texture

Hot rolled products like hot rolled steel bars are used in the welding and construction trades to make railroad tracks and i beams for example.
Hot rolled steel sheet texture. In the conventional hot rolled strip the texture is inhomogeneous through the thickness and the bulk texture is dominated by the texture at mid thickness. There are three main visual differences between the two processes. Full hard half hard quarter hard and skin rolled. In comparison a cold rolled steel product with the same chemical composition has a yield strength of 365 mpa.
In this study we try to quantitatively predict hot rolled steel sheet texture after deformation and transformation by linking the crystal plasticity model with the variant selection model. Full hard rolling reduces the thickness by 50 while the others involve less of a reduction. The total texture is thus not dominated by intense peaks at a certain thickness location. Alternatively cold rolled steel has sharp edges a very smooth surface texture and an oily or greasy feel to it.
C1008 1010 hr steel sheet astm a1011 a569 hot rolled steel sheets are the most economical steel sheets available for a wide variety of applications hr steel sheets are easy to weld form and drill and has a slight grainy surface. The possible orientations transformed from the copper and. In the asymmetrical hot rolled strip the texture is more uniform through the thickness. As an example a hot rolled steel product may have a yield strength of 235 mpa.
The texture of hot rolled steel sheet has a substantial influence on the textural evolution of the cold rolled and annealed steel sheets. Hot rolled steel is used in situations where precise shapes and tolerances are not required. Popular uses for hr steel sheet include. Transformation texture and orientation relation ship in hot rolled steel sheet major features of texture in hot rolled steel sheets appear fig.
Automotive panels tool boxes hoppers drip pans fuel tanks trailer siding roofing etc. The rolls induce plastic deformation. Hot rolled steel has rounded edges a rough surface texture and no grease on its finish. The development processes of steel texture are broadly divided into deformation recrystallization and transformation.
In this study the effects of finishing temperature in hot rolling ft ranging from ferrite region to austenite region on the microstructure and texture of cold rolled and continuously annealed ultra low. Thus the yield strength of cold rolled steel is higher than that of hot rolled steel. Magnetic brinell 95. A a typical α texture of hot rolled steel sheets and b an example of rolling textures in fcc metal φ2 45 section.
Cold rolled steel is then annealed to induce ductility in the cold rolled steel which is simply known as a cold rolled and close annealed. Cold rolled steel is essentially hot rolled steel that has had further processing. Cold rolled sheets and strips come in various conditions.
