How useful is alloy steel?

Steel is an alloy and it is obtained by mixing iron with carbon and some other elements. But steel can be further combined with other elements to obtain alloy steel. Alloy steels have a wide range of uses.

Stainless steel is one of the most popular and renowned alloy steels; it contains chromium, nickel and manganese. It is hard and strong, and resists heat and corrosion. Therefore stainless steel is used to make a wide range of objects ranging from cutlery and cookware to lifts and subway trains, from safety pins and furniture to car engines and chemical plants.

Manganese alloy steels are used to make rock crushers, power shovels and other machines, which have to be extremely tough and strong. Carbon steel is used for building bridges, cutting tools and high strength wire.
