A204 steel plate is a low-alloy pressure vessel grade steel used primarily in the manufacture of boilers and pressure vessels for various industries. The material has high strength, good toughness, and excellent weldability, making it suitable for use in harsh environments.
A204 steel plate is available in three grades: Grade A, Grade B, and Grade C. Each grade has its own unique properties and composition. A204 grade A is a low-carbon steel with maximum thickness of 2 inches, while A204 grade B and A204 grade C have higher carbon content and can be used for thicker plates.
The properties of A204 steel plate vary depending on the grade and composition. Its typical tensile strength ranges from 65 to 85 ksi (or 448-586 MPa), while the yield strength ranges from 37 to 60 ksi (or 255-414 MPa). The material also has good impact resistance at low temperatures and can maintain its properties at elevated temperatures.
Overall, A204 steel plate is a reliable and versatile material used in the construction of pressure vessels and boilers. Its high strength, toughness, and weldability make it suitable for use in various industrial applications.
