Samuel Steels, located in Abuja, Nigeria, has built a solid reputation as a manufacturer and supplier of Carbon Steel A334 Grade 9 Tubing. This tubing is celebrated for its remarkable toughness, strength, and performance in low-temperature conditions. Whether seamless or welded, these tubes are crafted to meet the rigorous demands of industries that work in cryogenic and sub-zero environments. Samuel Steels is committed to ensuring that every A334 Gr 9 tube is produced in line with international standards, guaranteeing top-notch dimensional accuracy, weldability, and reliability. The company caters to essential sectors like power generation, oil and gas, petrochemical, and process industries, providing high-quality carbon steel tubing solutions.
The composition of Carbon Steel A334 Grade 9 Tubing includes carbon (up to 0.15%), manganese (0.30–0.80%), molybdenum (0.44–0.65%), silicon (0.13–0.32%), along with trace amounts of phosphorus and sulfur. This blend strikes a perfect balance between strength and ductility while ensuring excellent impact resistance at low temperatures. With a minimum tensile strength of 415 MPa and a yield strength of 240 MPa, this tubing promises reliable performance under pressure. Its fine-grained structure, achieved through careful heat treatment, boosts its toughness, corrosion resistance, and ability to handle thermal stress in cryogenic applications.
