Quizplus · Accepted Answer

Both carbon and nickel can be added to steel to modify its properties. Carbon increases the hardness and strength of steel, while nickel improves its toughness, corrosion resistance, and temperature resistance. Therefore, adding both elements can create a steel with a desirable combination of strength, toughness, and resistance to wear and tear. Copper, on the other hand, is not typically added to steel as it does not significantly improve its properties.
