The A299/A299M-17 steel grade is a standard specification for pressure vessel plates, carbon steel, manganese-silicon. It has specific mechanical properties and chemical composition that make it suitable for use in various applications.
The chemical composition of A299/A299M-17 steel grade includes a maximum carbon content of 0.28%, a maximum manganese content of 0.90%, and a maximum silicon content of 0.15-0.40%. These alloying elements enhance the strength, toughness, and weldability of the steel.
The mechanical properties of A299/A299M-17 steel grade include a minimum yield strength of 50 ksi (345 MPa) and a minimum tensile strength of 80-100 ksi (550-690 MPa). These properties make it suitable for use in pressure vessels, boilers, and storage tanks that require high strength and resistance to corrosion.
The steel grade is primarily used in low-temperature applications, where toughness and impact resistance are important. It is commonly used in the construction of cryogenic storage tanks, LNG (liquefied natural gas) storage tanks, and other pressure vessels that operate at extremely low temperatures.
In summary, the A299/A299M-17 steel grade has specific mechanical properties and chemical composition that make it suitable for use in pressure vessels and other applications that require strength, toughness, and corrosion resistance. By understanding these properties and applications, engineers and designers can make informed decisions about the use of this steel grade in their projects.
