Luke Steel, a reputable manufacturer and supplier of Carbon Steel A334 Grade 9 Tubing with headquarters in Houston, Houstan, specialises in cold-drawn seamless tubes made for low-temperature applications. Luke Steel, which has a solid reputation for accuracy, quality, and adherence to ASTM A334 standards, offers tubing solutions that perform exceptionally well in below-freezing temperatures. Because of its improved impact strength and weldability, grade 9 tubing is perfect for demanding sectors like power generation, oil and gas, and petrochemicals. Luke Steel’s customer-first strategy guarantees on-time delivery, technical assistance, and reliable product quality that is adapted to various project requirements.
Carbon (0.20% max), manganese (0.50–1.06%), phosphorus (0.030% max), sulphur (0.030% max), and silicon (0.18–0.37%) make up Carbon Steel A334 GR 9 Tubing. At low temperatures, this composition guarantees exceptional toughness and durability. The tubing has exceptional impact resistance at -50°F (-45°C) and a minimum tensile strength of 60,000 psi and a minimum yield strength of 30,000 psi. For consistent mechanical qualities and dimensional accuracy, A334 Gr 9 is cold-drawn and normalised. It is perfect for low-temperature pressure systems and structural applications in demanding environments because it is also very formable and weldable.
