Answer
Iron is often converted to alloy steels to increase its strength and resistance to rusting. Both high speed steel and stainless steel offer very high strength compared to iron, making them more suitable for various applications. Additionally, the resistance to rusting is high in alloy steels, enhancing their durability in adverse conditions.
