Alloy Steel is an iron based alloy containing carbon (usually less than 2.5 % by weight), manganese (usually greater than 0.25 % by weight), and a variety of elements in total amounts between 1.0 % and 50 % by weight to improve its mechanical properties. Low Alloy Steel (less than 5 %) to increase strength or hardenability, and High Alloy Steel (over 5 %) to achieve special properties, such as corrosion resistance or extreme temperature stability.
