An industrial hot rolled extra-low carbon steel with the following composition was used in this work: 0.048C – 0.191Mn – 0.010P –0.001Si –0.040Al –0.031N (wt-%). The hot rolled sheet with an initial thickness of 3 mm was cold rolled in a pilot plant to 8 different degrees of cold reduction in the range between 12 and 81% at 10% intervals.sp.info 2B, 2D and BA Cold Rolled Finishes - ASSDACold rolled finishes apply to flat products such as sheet or coil, with thickness less than about 5mm and usually less than 3mm. They are firstly hot rolled into a strip (or cast into a slab which is hot rolled into a strip) and then cold rolled. Cold rolling reduces the thickness by at least 50%. This smooths the surface, refines the grain structure and causes differences in the mechanical properties along and across the rolling direction. In the case of austenitic and duplex alloys, the process hardens and strengthens th…See more on assda.asn.ausp.info The Effect of Ultrafast Heating in Cold-Rolled Low …metals Article The Effect of Ultrafast Heating in Cold-Rolled Low Carbon Steel: Recrystallization and Texture Evolution Felipe M.
