A572 steel

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.

Grades
A572 steel has five different grades: 42, 50, 55, 60 and 65. Each of these grades differ in their mechanical properties and chemical composition.

Forms
A572 steel is produced in a variety of different steel forms, which include:
 * Plates
 * Bars
 * Structural Shapes
 * Channels
 * I-Beams
 * Angles
 * Wide Flange Beams
 * Sheet Piling

Applications
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.
