What alloy is steel tubing?

Steel tubing is typically made from an alloy called carbon steel or mild steel. Carbon steel is an alloy of iron and carbon, with carbon content typically ranging from 0.2% to 2.1% by weight. It is the most common type of steel used in various applications, including tubing. Other elements, such as manganese, phosphorus, sulfur, and trace amounts of other elements, may also be present in steel tubing depending on the specific requirements and manufacturing processes. The presence of these additional elements helps to enhance the properties of the steel, such as strength, durability, and corrosion resistance.
