HRS Hot Rolled Seamless Tube95

1. Product Name:HRS Hot Rolled Seamless Tube

2. Product Description:HRS Hot Rolled Seamless Tube Hot rolling seamless steel tube: hot rolling is relative to cold rolling, cold rolling is at the recrystallization temperature below the rolling, and hot rolling is at the recrystallization temperature above the rolling. The Hot Rolled Seamless Tube advantages and disadvantages It HRS Hot Rolled Seamless Tube can destroy the casting structure of ingot and refine the grain of steel, and eliminate the defects of microstructure, so as to make the steel microstructure compaction, mechanical properties have been improved.This improvement is mainly reflected in the rolling direction, so that the steel is no longer isotropic to a certain extent;Bubbles, cracks and porosity formed during pouring can also be welded under high temperature and pressure. Folding defect HRS Hot Rolled Seamless Tube After hot rolling, the non-metallic inclusions (mainly sulfides and oxides, as well as silicates) inside the steel are compressed into thin slices, resulting in stratification (interlayer).Lamination greatly aggravates the tensile properties of the steel along the thickness direction, and it is possible for the lamellar tear to occur when the weld seam shrinks.The local strain induced by weld shrinkage is often several times that of yield point strain, which is much larger than that caused by load. HRS Hot Rolled Seamless Tube Residual stress caused by uneven cooling.The residual stress is the internal self-phase equilibrium stress under the action of no external force, all kinds of sections of hot rolled steel have this kind of residual stress, the general section size of the larger, the larger the residual stress.Although the residual stress is self-phase equilibrium, it has certain influence on the behavior of steel members under external force.Such as deformation, stability, fatigue and other aspects may have adverse effects. HRS Hot Rolled Seamless Tube It is difficult to control the thickness and side width of hot-rolled steel products.We are familiar with heat expansion and cold contraction, because at the beginning of hot rolling, even if the length and thickness are up to the standard, there will still be a certain negative difference after cooling. The wider the negative difference edge is, the thicker the thickness is, the more obvious it will be.So for large sizes of steel, you can't be too precise about the width, thickness, length, Angle, and edge of the steel.
