405 SS

Our inventory now includes Alloy 409 (UNS S40900) in sheet, sheet coil, plate, round bar, processed flat bar and tubular products.

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.

Our inventory now includes Alloy 422 (UNS  S42200) in round bar.

With better strength at higher temperatures, Type 422 (S42200) is an appealing alternative to Type 403.  Type 422 is a hardenable martensitic stainless steel which is being widely used for high temperatures up to 1200°F. It is capable of being heat treated to various high strength levels. It is often used in aircraft and power industries who require high strength/weight ratios from room temperature to 1200°F.
