What is Low Temperature Carbon Steel A333 Gr 4 Pipe​​​​​​​​?

The ASTM A333 Grade 4 pipe is crafted from a fine-grain carbon-molybdenum steel alloy, designed to perform in temperatures as low as -45°C (-50°F). Its chemical makeup includes a maximum carbon content of 0.12%, manganese ranging from 0.50% to 1.05%, and minimal phosphorus and sulfur at 0.025% each, along with a significant molybdenum content of 0.45% to 0.65%. This unique blend enhances the pipe’s strength, toughness, and resistance to low-temperature embrittlement. With a minimum yield strength of 275 MPa and a minimum tensile strength of 485 MPa, this grade boasts improved mechanical properties. Its fine grain structure and low carbon content also contribute to excellent weldability and impact resistance in cryogenic conditions.
