Q255B Carbon Steel Coil

Q255B Carbon Steel Coil is a common steel. It mainly contains iron and an appropriate amount of carbon and other elements. It has a certain strength and ductility, and the yield strength is not less than 255 MPa. Widely used in construction, machinery manufacturing, etc., it is a common choice for manufacturing steel structures and parts, but its oxidation resistance and corrosion resistance need to be improved.
