WebThe simplest steels are iron (Fe) alloyed with carbon (C) (about 0.1% to 1%, depending on type) and nothing else (excepting negligible traces via slight impurities); these are called carbon steels. However, the term "alloy steel" is the standard term referring to steels with other alloying elements added deliberately in addition to the carbon.

WebPhosphorus is also important in the production of steel. Phosphates are ingredients in some detergents, but are beginning to be phased out in some countries. This is because they can lead to high phosphate levels in natural water supplies causing unwanted algae to grow. Phosphates are also used in the production of special glasses and fine ... WebJan 5, 2012 · Phosphorus in the charge could be at higher than usual levels for DRI, HBI, pig iron, and hot metal, depending on the iron ore source. Some steels require particularly low P levels to avoid too high ductile/brittle transition temperature or tempering brittleness. iready analyzing development of central ideas
