SUH409L AISI 409 DIN 1.4512 Hot Rolled Stainless Steel Round Bars

409 is a low cost ferritic stainless steel.
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.
