The A542/A542M-13 steel grade is a low-alloy steel primarily used in the construction of pressure vessels. It is specifically designed for high-temperature service and offers excellent creep resistance and high strength.
The A542/A542M-13 steel grade has a specific chemical composition that includes various elements. These elements and their percentages are as follows:
– Carbon (C): 0.15-0.30%
– Manganese (Mn): 0.40-0.90%
– Phosphorus (P): 0.035% maximum
– Sulfur (S): 0.035% maximum
– Silicon (Si): 0.15-0.50%
– Nickel (Ni): 0.40-1.00%
– Chromium (Cr): 0.40-1.00%
– Molybdenum (Mo): 0.15-0.50%
The A542/A542M-13 steel grade exhibits excellent mechanical properties, which make it suitable for high-temperature applications. Some key mechanical properties of this steel grade include:
– Tensile Strength: 580-760 MPa
– Yield Strength: 415 MPa minimum
– Elongation: 18% minimum
– Impact Toughness: At -150°F (-101°C), the average energy requirement for breaking ten samples is 28 ft·lbf (38 J) minimum.
Due to its unique combination of high strength and creep resistance, the A542/A542M-13 steel grade finds its main application in the manufacturing of pressure vessels that operate at elevated temperatures. These vessels include reactors, heat exchangers, boilers, and other equipment used in the petrochemical, chemical processing, and power generation industries.
The A542/A542M-13 steel grade is defined by the ASTM A542/A542M-13 standard. This standard provides the specifications and requirements for the steel grade to ensure its quality, performance, and compatibility with various applications.
The A542/A542M-13 steel grade may have corresponding grades in other international standards or specifications. However, the specific corresponding steel grades may vary depending on the standards and specific requirements of different countries or organizations. It is essential to refer to the appropriate international and national standards for accurate and specific corresponding grades.
