Advantages of Carbon Steel compared to other Metals. 1) Faster heating effect. For kitchen use this is especially important as it saves time and reduces the amount of energy used. Stainless Steel, on the other hand, is known to be a poor conductor of heat.
Iron is the major component of steel, with carbon being a distant second, at between 0.2% and 2.14%, depending on the grade. Carbon is the most cost-effective way to alloy iron, but other metals can be used to augment the element and to give the metal certain properties. The metal known as cast iron is actually steel that has a very high carbon content, which gives it a lower melting point and greater castability.
