A533 Pressure Vessel Carbon Steel Coil description

A533 pressure vessel steel coils are typically subjected to quenching and tempering heat treatment, and are available in five different strength grades: Class A, Class B, Class C, Class D, and Class E. These ASTM A533 pressure vessel steel coils exhibit exceptional low-temperature impact toughness and mechanical properties, making them well-suited for use in low-temperature conditions. Widely employed in low-temperature separation processing and liquefied gas storage, these coils are commonly utilized in applications such as large-scale vacuum low-temperature liquefied natural gas (LNG) storage equipment. Additionally, they are frequently utilized in the strip area of nuclear reactor vessels, where material properties may be influenced by intense radiation.
