How does 441 stainless compare to 409?

Both of these stainless steel grades have a ferritic microstructure. However, 441 has the addition of niobium as a stabilizer and a much higher chromium content. This produces a stainless steel that has more creep, corrosion, and oxidation resistance at even higher temperatures. They share many of the same applications, including automotive exhaust systems and tubular manifolds. One reason 409 might be chosen over 441 is for its improved weldability, or where end uses require significant weldments.

 

 

Advantages/Disadvantages

This stainless steel grade provides some of the best strength in high temperature and gas exhaust environments. One of the disadvantages of this stainless steel grade is that it shows diminished weld quality when compared across the 400 stainless steel category. It is not heat treatable.
