Hot rolled mechanical tubing is produced by heating a solid billet or bar and then rotary piercing it as it rotates on rollers. Then the final processing through multiple pass size-reducing mills occurs. Tolerances and finish are similar to other hot worked steel products.
Hot rolled steel is mill process by which the steel is roll pressed at a high temperature. Generally, the temperature for hot rolled steel exceeds 1700°F. Cold rolled steel is a process by which steel is roll pressed at room temperature. It is important to note that both hot rolled steel and cold rolled steel are not steel grades. They are the ...
