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.
In the US, the common designation is: Alloy Steel AISI 6150. It has a little Chromium and Vanadium added to the melt to make it more hardenable and more ductile than a straight carbon steel. Good for tools that see abuse like wrenches and chisels. (Chrome plating on the outside is just to prevent rust.)
