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.
