409 Stainless Steel Sheet/Plate:

Grade 409 is a stabilized ferritic general purpose stainless steel with 11% chromium. It is especially useful for applications requiring oxidation or corrosion protection beyond the capability of carbon steel and some coated steels. 409 has good oxidation resistance and formability, but lower corrosion resistance due to the chromium content. 409 is not as corrosion resistant as 304, 430 or 439 grades, however, 409 is far superior to mild carbon steel. 409 can be formed by roll forming, stretch bending, deep drawing or pressing.  In the annealed condition 409 does not harden when cold worked using mild roll forming techniques including pressing or stretch-bending. Welding performance for grade 409 is fair. This stainless steel material should not be used in impact-loaded structures, because in heat affected zones the grain structure can grow which may have a direct effect on the mechanical properties. 409 is commonly used for tubing and stampings in motor vehicle exhaust system applications.

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.
