Alloy Steel Wire


In Alloy Steels the addition of various elements in total amounts of 1.0% to 50% by weight is done to improve mechanical properties. Every steel is truly an alloy, but not all steels are called "alloy steels". However, the term "alloy steel" is the standard term referring to steels with other alloying elements in addition to the carbon. As a guideline, alloying elements are added in lower percentages (less than 5%) to increase strength or hardenability.
