When it comes to Carbon Steel SA178 Tubing, it mainly consists of iron with a carefully controlled amount of carbon, usually around 0.15–0.30%, along with trace amounts of manganese, phosphorus, and sulfur. This specific mix gives it a great balance of strength, ductility, and weldability. Mechanically, SA178 tubes boast a tensile strength of about 380–580 MPa, yield strength of 240–400 MPa, and an elongation of 20–25%, ensuring they hold up well under varying pressures. The tubing can handle moderate corrosion and thermal stress, making it perfect for welded and seamless construction in high-performance industrial systems.
