Luke Steel, Houston, USA is a reputable manufacturer and supplier of ASTM A333 Grade 7 Low-Temperature Carbon Steel Pipes that are relied upon across industries for excellence in quality and performance. Expertise in products designed to meet sub-zero requirements, Luke Steel caters to mission-critical applications like oil & gas, petrochemical, and power generation. These pipes are designed to have superior impact strength and notch toughness at temperatures as low as -45°C, providing reliability in harsh environments. In line with a strong focus on customer satisfaction, punctual delivery, and technical proficiency, Luke Steel is a first choice for cold-weather piping solutions.
ASTM A333 Grade 7 pipes are made from a low-temperature carbon steel alloy that has Carbon (≤0.19%), Manganese (≤0.90%), Phosphorus (≤0.025%), Sulfur (≤0.025%), Silicon (0.13–0.32%), Nickel (2.03–2.57%), and Chromium (max 0.30%). The material has a minimum tensile strength of 450 MPa, minimum yield strength of 240 MPa, and elongation of 30% in the longitudinal direction and 22% in the transverse direction. The pipes are heat-treated to maximize their microstructure, providing improved impact resistance and ductility for low-temperature service, particularly in cryogenic or arctic environments.
