SA178 Tubes are made of carbon steel with manganese and silicon elements. Standard composition consists of Carbon (C) ≤ 0.06%, Manganese (Mn) 0.27–0.63%, and Silicon (Si) ≤ 0.10%. These tubes have outstanding mechanical strength, with a tensile strength of a minimum of 47 ksi (325 MPa), yield strength of 26 ksi (180 MPa), and elongation of at least 35%. Their mechanical properties are perfect for boiler and heat-exchanger use, where dependability in thermal and mechanical stress is necessary.
