What is Low Temperature Carbon Steel A333 Gr 4 Pipe?

ASTM A333 Grade 4 Pipes are fabricated from a proprietary low-temperature carbon steel alloy containing carbon (≤0.12%), manganese (0.50–1.05%), silicon (0.18–0.37%), nickel (0.47–0.98%), chromium (0.44–1.01%), copper (0.40–0.75%), and aluminum (0.04–0.30%), with traces of phosphorus and sulfur (both ≤0.025%). These pipes have a minimum tensile strength of 415 MPa and yield strength of 240 MPa, with 30% elongation in the longitudinal direction and 16.5% in the transverse direction. Heat-treated to achieve their best microstructure, they provide superior impact resistance and structural stability in cryogenic and sub-zero temperatures.

Uses of Low Temperature Carbon Steel A333 Gr 4 Pipe

ASTM A333 Grade 4 Pipes find widespread usage in industry demanding assurance of performance in very low temperature conditions. These are used in heat exchangers, condensers, and piping systems for LNG terminals, offshore oil drilling platforms, and cryogenic gas transportation systems. Their high impact resistance and ductility at subfreezing temperatures render them applicable in petrochemical, power generation, and chemical processing systems. These pipes are also well suited for the transportation of liquefied gases and refrigerated fluids in extreme service environments, providing safety, efficiency, and extended life. Their capacity to retain mechanical properties to -45°C positions them as critical components for severe low-temperature engineering systems.
