Types of alloy steelThere are two kinds of alloy steel – low-alloy steel and high-alloy steel. As mentioned earlier, the composition and proportion of alloying elements determine the various properties of alloy steel. Low-alloy steels are the ones which have up to 8% alloying elements whereas high-alloy steels have more than 8% alloying elements. Alloying elements There are around 20 alloying elements that can be added to carbon steel to produce various grades of alloy steel. These provide different types of properties. Some of the elements used and their effects include: Aluminium – can rid steel of phosphorous, sulfur and oxygenChromium – can increase toughness, hardness and wear resistanceCopper – can increase corrosion resistance and harnessManganese ...
