Hot rolled steel tubing is carbon steel rolled at a temperature above its recrystallization point, which is usually about 1,000 degrees Fahrenheit. When steel is heated past a recrystallization point, it becomes more malleable and is easily formed and shaped. Benefits of this steel tubing type are: When hot rolled steel tubes cool off, they ...

Hot rolled seamless (HRS) tube (also known as HFS or Hot finished seamless) is a lower-cost product than CDS tube and is a good material for applications that do not require the close dimensional tolerances and quality of surface finish that CDS tube provides. If tight tolerances are required, machining is used to finish the product to exact specifications.

Reheating furnace reheats the cooled hollows to the temperature required for the last forming step. The stretch-reducing mill represents the third main formi...
