What is A572 steel used for

What is ASTM A572 specification?

The ASTM A572 specification is the Standard Specification for High-Strength Low-Alloy Columbium-Vanadium Structural Steel for plates used in general construction and structural applications.

ASTM A572 grades are used in a wide variety of structural applications in many market segments.

WHAT IS A572 STEEL PLATE?

ASTM A572 steel plate is a popular grade of high-strength low-alloy (HSLA) steel that is typically used in structural applications. A572 steel contains chemical alloys that enhance the material’s hardness and ability to bear weight, and this material is lightweight relative to steel grades with similar compositions.

ASTM A572 includes five grades with specified minimum yield strengths of 42, 50, 55, 60, and 65 ksi, respectively. Each of these grades have slight differences in their mechanical properties and chemical compositions, which may make them more fitting for certain applications. A572-50, however, is the most common A572 grade.

Benefits of A572

A572 steel plate is lightweight, yet offers great strength, ductility and machinability, making it ideal for use in structural applications. These properties make A572 relatively simple to shape into different structures while also maintaining the ability to bear great stresses and loads. A572 is also one of the most economically priced grades of steel plate.

A572 Equivalent Plate Grades

The chemical composition and mechanical properties of A572 steel plate are governed by ASTM code. While ASTM regulations are widely accepted around the world, some countries or projects may require steel plate materials that meet other standards. For projects requiring EN standard steel plate,S355 may be able to be used in place of A572, as these grades are generally considered equivalent.

While not exact equivalents, other mild carbon or HSLA plate grades – such as ASTM A36 may also be suitable for similar applications, as these grades often have similar chemical and mechanical properties.
