Hot rolled seamless steel tube: hot rolling is relative to cold rolling, cold rolling is under the recrystallization temperature, and hot rolling is above the recrystallization temperature.

Hot-rolled seamless tube can destroy the cast structure of steel ingot, refine the grain of steel and eliminate the defects of microstructure, so that the microstructure of steel can be compacts and the mechanical properties can be improved.The improvement is mainly reflected in the direction of rolling so that the steel is no longer isotropic to some extent.The bubbles, cracks and looseness formed during pouring can also be welded under high temperature and pressure.
