Which element is sometimes added to stainless steel?

• A. Chromium
• B. Nickel
• C. Molybdenum
• D. Manganese

Answer: (D)

Stainless steels are engineered alloys where small amounts of different elements are added to tailor properties like corrosion resistance, strength, and cost. Manganese is one of those elements that is sometimes included to adjust the alloy’s behavior without relying as much on nickel. In many stainless grades, especially the 200-series, manganese can partly substitute for nickel to preserve an austenitic structure while lowering cost. It also helps as a deoxidizer during steelmaking and can improve workability. Because of this selective use in certain grades, manganese is the element described as sometimes added to stainless steel.
