Which of the following element is not present in SS 304?

Explanation:

Stainless steel:

• Stainless steel is an alloy (mixture of two or more metals) consisting of iron, chromium, nickel, carbon, etc.
• Stainless steel is a metal alloy, made up of steel mixed with elements such as chromium, nickel, silicon, aluminum, and carbon.
• Iron is mixed with carbon to produce steel which is the main component of stainless steel.
• Chromium is added to make it resistant to rust.
• Stainless steels are steels containing at least 10.5% chromium, less than 1.2% carbon, and other alloying elements.
• Stainless steel's corrosion resistance and mechanical properties can be further enhanced by adding other elements, such as nickel, molybdenum, titanium, niobium, manganese, etc.
• It has high structural strength as well as resistance to corrosion.
• Stainless steels are not confined to applications requiring resistance to atmosphere corrosion.
• They are used extensively for chemical plant and food processing equipment where they combine corrosion resistance at elevated temperatures.
• Type 304 stainless steel is a T 300 Series austenitic Stainless Steel.
• It has a minimum of 18% chromium and 8% nickel, combined with a maximum of 0.08% carbon.
• It is defined as a Chromium-Nickel austenitic alloy.
• Grade 304 is the standard "18/8" stainless that we see in our pans and cookery tools.
