Carbon Steel ASME SA 179 Tubing is a low-carbon steel grade containing around 0.06–0.18% carbon, 0.27–0.63% manganese, and minimal sulfur and phosphorus. This composition gives it exceptional ductility, making it ideal for cold-drawing and tight dimensional tolerances. Mechanically, SA 179 provides high tensile strength, excellent elongation, and outstanding thermal conductivity—key for heat exchanger and condenser applications. Its smooth finish, uniform wall thickness, and superior bending and flaring characteristics make it a preferred choice where precision fabrication and efficient heat transfer are essential.
