Grade 409 Seamless Stainless Steel Tube High Temperature Corrosion Resistance
Grade 409 Stainless Steel Tube High-Temperature Corrosion Resistance
Product specification
Grade 409 stainless steel is a Ferritic steel that offers good mechanical properties and high-temperature corrosion resistance. It is commonly considered as a chromium stainless steel, with applications in exhaust systems of automobiles and applications that demand weldability.
Grade 409 steels are also available in highly stabilized forms, such as grades S40930, S40920 and S40910. The stability of these grades is provided by the presence of niobium, titanium, or both, in the composition of steels.
Key Properties
The properties given below relate to annealed tubing of ASTM A268. The specified properties may not be similar to other products such as bar and coil.
