A533 Grade C is a low alloy steel plate, specifically ASTM A533/ASME SA533 steel, known for its high strength, toughness, and good weldability, making it ideal for use in heavy-duty applications like boilers and nuclear reactor vessels. It is a heat-treatable steel, often subjected to quenching and tempering, and contains manganese, molybdenum, and nickel to enhance its durability and resilience, particularly at low temperatures.
Product: Hot rolled manganese-molybdenum and manganese-molybdenum-nickel alloy steel plates for use in the quenched and tempered condition for the construction of welded pressure vessels.
