ASTM A572 steel is a common high strength, low alloy (HSLA) structural steel used in the United States. A572 steel properties are specified by ASTM International standards.
A572 steel has five different grades: 42, 50, 55, 60 and 65. Each of these grades differ in their mechanical properties and chemical composition.
A572 steel is produced in a variety of different steel forms, which include:
A572 steel is typically used in structural applications due to its high strength, ductility, weldability and corrosion resistance. These applications include structural sections, reinforcing bars, bridges, skyscrapers and houses.
