Typically made from mild carbon steel with a carbon content of about 0.25%, Carbon Steel BS1387 Pipes also include controlled amounts of manganese, phosphorus, sulfur, and silicon to boost their strength and machinability. They usually showcase tensile strengths between 400 MPa and 550 MPa, with yield strengths around 250 MPa. This well-balanced composition grants the steel good ductility, weldability, and resistance to deformation under mechanical stress. Available in various thicknesses, these pipes come in both galvanized and black-coated options to enhance corrosion resistance and prolong service life.
