Question 2

What structure is 304 stainless steel?

    Correct Answer: B

    304 stainless steel is classified as an austenitic stainless steel. This category is known for its excellent corrosion resistance and weldability, largely due to its high chromium and nickel content. Austenitic stainless steels are also non-magnetic and cannot be hardened by heat treatment. Common applications of 304 stainless steel include kitchen equipment, chemical processing equipment, and food processing machinery.
