SA204 Grade C is a molybdenum (Mo)-alloy steel specified by ASME, primarily used for high-temperature welded pressure vessels in the oil, gas, and chemical industries. It is known for its good heat and corrosion resistance due to the molybdenum content and offers enhanced mechanical properties at elevated temperatures.
