Carbon Steel Flat Bar

Product description:

Carbon steel, also known as carbon steel, is an iron-carbon alloy with an internal carbon content of nearly 2%. It can be used as a general engineering structure and ordinary mechanical parts, with complex manufacturing shapes, high mechanical property requirements, and difficult to form by forging and other methods in the process.
