General Info About 441

441 stainless steel sheet is a ferritic stainless steel that is niobium stabilized. It shows good high temperature strength as well as creep, oxidation, and corrosion resistance.

More Details About 441

  • 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.

  • Industries

    It is seen in the architecture, food service, automotive, and appliance industries.

  • Applications

    This grade is most suitable for drawn parts and bent tubing. Applications include appliances, heat exchangers, food and kitchen equipment, and automotive exhaust systems.

  • Machining

    It has good machinability.

  • Welding

    It has limited weldability.

  • Heat Treatment

    This stainless steel grade cannot be hardened by heat treatment.

Frequently Asked Questions

  • 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.

  • What makes 441 more corrosion resistant than 409?


    At 18% vs. 11%, the higher chromium content in 441 gives it the extra boost of corrosion and oxidation resistance.

  • In what finishes is this stainless steel grade available?


    Kloeckner Metals supplies 441 stainless steel in 2B and 2D, #3 and #4 polish, appliance and rolled on, and bright annealed finishes.
