 Fractional Tubing
Fractional Tubing
Fractional tubing is often used in commercial applications that require corrosion resistance and good strength. MicroGroup fractional tubing starts at 1/32″ OD and is generally stocked in 304 stainless steel and 316 stainless steel but is also available in many other metals and alloys in a variety of specifications. It is typically stocked in the annealed temper condition and is available as welded tubing (welded and drawn) or seamless tubing.
Fractional stainless steel is normally available in commercial ratings such as ASTMA269, ROHS, MilT8504 and ASM5570. Note that MicroGroup offers the inhouse capability to produce custom sizes and hold the chemical composition of the starting specification to reduce lead times.
For sizes or alloys not listed below, or to place an order, call 8002558823. To purchase standard stock tubing please visit our Online Store.
