Hot Rolled St37 St53 Mild Carbon Tube

Hot rolled steel pipe Hot rolling is relative to cold rolling. Cold rolling is rolling below the crystallization temperature, while hot rolling is rolling above the recrystallization temperature. Advantages of Hot Rolled Smls Steel Pipe It can destroy the casting structure of ingot, refine the grain of steel, and eliminate the defects of microstructure, so that the steel structure is dense and the mechanical properties are improved. This improvement is mainly along 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. Steel Pipe can be divided into Cold Drawn Smls Steel Pipe Hot Rolled Smls Steel Pipe Galvanized Steel Pipe.
