Alloy Steel is a derivative of carbon steel where element is added or deleted to yield certain properties. Typically these properties include machinability, wearability, and strength. An iron-based mixture is considered to be an alloy steel when manganese is greater than 0.165%, silicon over 0.5%, copper above 0.6%, or other minimum quantities of alloying elements such as chromium, nickel, molybdenum, or tungsten are present. Basically alloy steel is classified into two groups: Low Alloy Steel and High Alloy Steel.
Ventura Alloy And Steels stocks and supplies alloy steel in different grades in Rounds, Squares and Flats with various size ranges.
