Frequently Asked Questions

  • What are some of the differences between this grade and 304 stainless?

    ANSWER:

    There are a number of key differences between 409 and 304. For one, they contain different microstructures. 409 is a ferritic steel, while 304 is an austenitic steel. This leads to differences in mechanical properties. 304 is a higher strength stainless steel, and due to a higher percentage of nickel and chromium it has better corrosion resistance. 409 shows better oxidation resistance at medium strength levels.

  • What is the max Rockwell hardness of this stainless steel grade?

    ANSWER:

    The max Rockwell hardness for 409 stainless is B95.
