A533 Pressure Vessel Carbon Steel Coil Description

Usually coming with quenching and tempering heat treatment, A533 pressure vessel steel is available in five different strength grades: Class A, Class B, Class C, Class D, and Class E. ASTM A533 pressure vessel steel coil has excellent low temperature impact toughness and mechanical properties and is preferred in low temperature conditions. A533 pressure vessel steel coils are widely used in low-temperature separation processing, liquefied gas storage and other fields, such as large-scale vacuum low-temperature liquefied natural gas (LNG) storage equipment. At the same time, the coils are often used in the strip area of nuclear reactor vessels, where material properties may be affected by strong radiation.
