What are Alloys?

An alloy is metal prepared by adding other metals or non-metals to a basic metal to secure desirable properties. Alloy steel is steel containing substantial quantities of elements other than carbon and the commonly-accepted limited amounts of manganese, sulfur, silicon, and phosphorus. Addition of such alloying elements is usually for the purpose of increased hardness, strength, or chemical resistance. The elements most commonly used for forming alloy steels are: nickel, chromium, silicon, manganese, tungsten, molybdenum, and vanadium.

Why Alloys?

To improve strength while at the same time to save weight. Some alloys also improve durability. Alloys also enhance heat treatability.

Cost Savings?

Cost savings occur by reducing the thickness of the metal used. Due to its increased strength, thickness reduction and weight savings are easier to accomplish. Typical examples may be found in the automotive industry.
