What is Low Temperature Carbon Steel A333 Gr 3 Pipe?
Our Low Temperature Carbon Steel A333 Grade 3 Pipes are made from a fine-grain carbon-manganese steel, enhanced with controlled amounts of silicon and other trace elements to boost their mechanical properties. These pipes demonstrate remarkable impact toughness and tensile strength, even at frigid temperatures as low as −45°C. They also offer excellent weldability, machinability, and corrosion resistance in mild environments. With a minimum yield strength of 240 MPa and a tensile strength ranging from 415 to 550 MPa, they ensure safe and reliable performance in low-temperature conditions.
