ASTM A268 Seamless TP409 Ferritic Martensitic Boiler Tubes
YUHONG Group offers ASTM A268 TP409 SMLS/WELDED ferritic martensitic stainless steel tubes and we sell these tubes in more than 70 countries up to now. This specification covers a number of grades of nominal-wall-thickness, stainless steel tubing for general corrosion-resisting and high-temperature service. Most of these grades are commonly known as the “straight-chromium” types and are characterized by being ferromagnetic.
TP409 stainless steel, due to its good corrosion resistance and high temperature strength, it is widely used in automotive exhaust systems, gas burners, waste incinerators, home appliances, and construction. In addition, it has good processing properties and is easy to cut, weld and form. Besides, due to its low cost, it is an economical choice in some applications where corrosion resistance is required.
