As a group, carbon steels are by far the most frequently used steels. Ferrite is the softest phase of steel which is largely responsible for the higher machinability of low carbon steel relative to other carbon … Low-carbon steel, also known as plain-carbon steel and Mild Steel contains a small percentage of carbon (0.05–0.25%C). Low-carbon steel, also known as plain-carbon steel and Mild Steel contains a small percentage of carbon (0.05–0.25%C). In stock and ready to ship. Low carbon steels consist primarily of ferrite, which is a solid solution phase of carbon dissolved in alpha-iron, a body centered cubic crystal. More than 85% of the steel produced and shipped in the United States is carbon steel. Low-carbon steels contain up to 0.30% C. The largest category of this class of steel … The key factor distinguishing low, medium and high carbon steel is the percentage content of carbon, and according to the different carbon percentage content, it’s divided into the following types: Low Carbon Steel : also know as mild steel, the percentage content of carbon … It is the most common form of steel because its price is relatively low while it provides … R. Evans, in Metalworking Fluids (MWFs) for Cutting and Grinding, 2012. It is the most common form of steel because its price is relatively low while it provides … Carbon steel.
