ASTM A533 Boiler vessel plates are manganese-molybdenum and manganese-molybdenum-nickel alloy steel plates suitable for welding pressure vessels. Often with quenching and tempering heat treatment, that is, quenching and tempering state supply. ASTM A533 boiler vessel steel is available in five different strength grades: Class A, Class B, Class C, Class D, and Class E. There are three levels of each category: level 1, level 2 and level 3.

Scope of application
ASTM A533 boiler vessel plate has excellent low temperature impact toughness and mechanical properties, and is usually used under low temperature conditions. ASTM A533 boiler vessel plate is widely used in low temperature separation processing, liquefied gas storage and other fields, such as large vacuum low temperature liquefied natural gas (LNG) storage equipment.
