5 COMMON ALLOYING ELEMENTS
Alloying elements are used to alter the mechanical and chemical properties of steel to give them advantages over standard carbon steel . While there are many alloying elements used to achieve various enhanced properties, certain elements are much more common than others. These are 5 common alloying elements: 1. Chromium Chromium Chromium added to carbon steel in percentages usually greater than 11% creates stainless steel. At this percentage and greater, the corrosion resistance of a steel vastly increases and oxidation of the iron is prevented in many conditions. The iron does not oxidize because the chromium will oxidize first and form a protective layer over the steel. Chromium also helps to improve mechanical properties, even in smaller amounts. It will increase the steel’s strength, hardness, and ability to be heat treated. Common steels with high amounts of chromium include grades 439, 309, 2205 stainless steels. Grade D2 tool steel also has significant...
