Hot Rolled Seamless (HRS) Steel Tubing - Hot Finished

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. Hot Rolled Seamless Steel Pipe - Permanent SteelHot rolled seamless steel pipe:Hot rolling is relative to cold rolling, cold rolling is rolling below the recrystallization temperature, and hot rolling is rolling above the recrystallization temperature.
