ASME SA268 TP409L Seamless Tube UNS S40903 Ferritic Stainless Steel Seamless Tube

Type 409 Stainless Steel is a Ferritic steel, known mostly for its excellent oxidation and corrosion resistance qualities, and its excellent fabricating characteristics, which allow it to be formed and cut easily. It typically has one of the lowest price-points of all the types of stainless steel. It has decent tensile strength and is readily welded by arc welding as well as being adaptable to resistance spot and seam welding. It is important to note that welding Type 409 does not impair its corrosion resistance.

Ferritic stainless steel features high corrosion resistance and oxidation resistance due to its high chromium content, but its mechanical properties and machinability are poor. It is widely applied to acid-resistant structures with little stress and is used as anti-oxidation steel. This steel type can resist the corrosion of atmospheric, nitric acid and saline solution. It features high temperature oxidation resistance and small thermal expansion coefficient. It can be used in nitric acid and food factory equipment, and can also be used to produce parts working at high temperature, such as gas turbine parts.
