From Wikipedia, the free encyclopedia. Alloy steel is steel that is alloyed with a variety of elements in total amounts between 1.0% and 50% by weight to improve its mechanical properties. Alloy steels are broken down into two groups: low-alloy steels and high-alloy steels.
An alloy is a mixture of two or more different metals. For example, brass is the alloy formed by mixing copper and tin. Non-metallic elements may also be included in alloys. For instance steel is made up of varying amounts of iron, carbon (non-metal), chromium, vanadium, and other ingredients.
