What Is Hot Rolled Seamless Carbon Steel TubePosted by zora li on November 2nd, 2022 Hot-rolled seamless carbon steel pipe: Hot-rolling is related to cold-drawing, and hot-rolling is performed above the recrystallization temperature of rolling. Advantages of hot rolled seamless pipe: Disadvantages of hot rolled seamless steel pipe: 2. Residual stress caused by uneven cooling. Residual stress is balanced by internal stress in the absence of external force. Regardless of various residual stresses such as hot-rolled steel sections, generally the larger the section size of the steel, the greater the residual stress. Although the residual stress is out of balance, it still has a certain influence on the performance of the steel member under load. Terms such as deformation, stability, fatigue resistance, etc. may have adverse effects. 3. Hot-rolled steel, in this aspect, the thickness and width of the edge are not well controlled. We are familiar with thermal expansion and cold contraction. Since the beginning of hot rolling, even the length and thickness are standard, and there will still be some negative differences in the final cooling. The wider and thicker the side width of this negative difference, the more obvious the performance. Therefore, for large steel, there is no rule that requires a very precise edge for the width, thickness, length, and angle of the steel edge.
