409L Stainless Steel Plate Stainless 409 ,Grade UNS40900 SUH409L Sheet 2D Finished
If you desire a stainless steel whose mechanical properties highly outshine its physical appearance than 409 stainless steel is your perfect match. 409 Stainless is ideally used in scenarios where a need for oxidation or even corrosion protection is wanted. As a titanium stabilized ferritic stainless steel, 409 is most commonly used in automotive exhaust systems where the environment can be quite taxing on the lifetime of the steel.

Features
Although susceptible to rust formation, making this grade of
stainless steel somewhat undesirable for decorative purposes, 409
is extremely resistant to various forms of gas corrosion.
Applications
409 is the perfect grade stainless steel to be used in automotive
applications where visual appeal is not a top priority. For this
reason and for its durability to gas corrosion, 409 is most
commonly used in truck exhaust systems, agricultural equipment, and
heat and gas turbine exhaust silencers.

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.
Although Alloy 409 is designed principally for the automotive exhaust industry, it has been successfully used in other industrial applications as well. Some examples of applications that call for Alloy 409 include:
