Product Information
Alloy 409 is a general purpose, chromium, titanium stabilized, ferritic stainless steel whose primary application is automotive exhaust systems. It contains 11% chromium which is the minimum amount for the formation of the passive surface film which gives stainless steels their corrosion resistance. It combines good elevated temperature corrosion resistance with medium strength, good formability, and overall cost. Alloy 409 resists corrosion strongly compared to carbon steel and is used as an alternative to carbon steel in mildly challenging environments where its high resistance to corrosion and high temperature oxidation gives an advantage. It is commonly used in applications where appearance is a secondary quality to mechanical properties and corrosion resistance.

Surface treatmentAbout surface treatment,it is the most important part.For the cold rolled surface is 2B,Hot rolled regular surface is No.1.Because the process is different and the application industry is different, their surface treatment requirements are also different. For cold-rolled plate, the base surface is 2B. Many customers are in the decoration industry, such as hotel decoration, so they have very high requirements on the surface treatment. Generally they will choose BA, HL, 8K, gold and other colors.
