Luke Steel is a well-known manufacturer and exporter of ASTM A333 Grade 9 low-temperature carbon steel pipes, proudly working from Houston, USA. With a heavy emphasis on durability, quality, and customer satisfaction, Luke Steel is expert in high-grade steel products that outperform in sub-zero conditions. Their A333 Gr. 9 pipes are designed with exceptional impact resistance and notch toughness at temperatures as low as -45°C and are perfect for cold climate and cryogenic applications. Supported by sophisticated manufacturing facilities and a good distribution network, Luke Steel has established a good name as a reliable steel supplier in the USA.
ASTM A333 Grade 9 carbon steel pipes are specially designed for low-temperature uses. Their content consists of carbon (≤0.20%), manganese (0.40–1.06%), phosphorus (≤0.025%), sulfur (≤0.025%), chromium (1.60–2.24%), and nickel (0.75–1.25%). They are heat-treated to provide maximum microstructure and toughness. They provide minimum tensile strength of 435 MPa, yield strength of 315 MPa, and elongation of 28% in the longitudinal direction. This blend of processing and elements provides superior mechanical performance and consistent ductility in low-temperature or cryogenic service conditions, particularly where safety and durability cannot be compromised.
