A533 Pressure Vessel Steel Plate

ASTM A533 pressure vessel steel plates are manganese-molybdenum and manganese-molybdenum-nickel alloy steel plates suitable for welding pressure vessels. There are three levels of each category: level 1, level 2 and level 3. Usually coming with quenching and tempering heat treatment, ASTM A533 pressure vessel steel is available in five different strength grades: Class A, Class B, Class C, Class D, and Class E. ASTM A533 boiler vessel plate has excellent low temperature impact toughness and mechanical properties and is commonly used in low temperature conditions. ASTM A533 pressure vessel steel plates 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 plates are often used in the strip area of nuclear reactor vessels, where material properties may be affected by strong radiation.
