DIN 1629/DIN 2391 St37.0/St44.0/St52.0/St52.3 Seamless Carbon Steel Tube Machine Production Line
Product Description
Available grades and size range
Carbon steel is an alloy with carbon and iron, with carbon content up to 2.1% by weight. The increase in the carbon percentage will raise steel's hardness and strength, but it will be less ductile. Carbon steel has good properties in hardness and strength, and it is less expensive than other steels.
