Do you know A36 steel plate? This blog post will give you a comprehensive understanding of A36 steel plates from the aspects of what they are, corresponding grades, physical properties and applications, so as to prepare for your project.

What is A36 steel plate?

A36 steel plate is a carbon structural steel plate mainly used to manufacture welded and bolted metal structures for industrial and civil buildings and bridge construction. This kind of steel plate is mainly composed of elements such as carbon, manganese, silicon and phosphorus, and is a low-carbon steel plate under the American ASTM standard.

Corresponding grades:

A36 steel plate is the American ASTM standard carbon structural plate, its executive standard is ASTM A36/A36M-03a, this kind of standard applies to riveted, bolted and welded structures for bridges and buildings, as well as structural steel qualities of carbon steel profiles, plates and bars for general purposes. In terms of chemical composition, A36 steel plate has a yield strength greater than or equal to 250 MPa, a tensile strength of 400-550 MPa and an elongation of ≥20%.

In China, the corresponding grade of A36 steel plate is Q235. Q235 is a quality grade symbol, and the quality grades are divided into A, B, C, D, and E, in the order of A grade is of poorer quality, and D grade is of the highest quality. In addition, depending on the method of deoxidation, the symbols can be F, b, Z and TZ, which stand for boiling steel, semi-sedated steel, sedated steel and special sedated steel, respectively.

Performance:

  1. In terms of chemical composition, the yield strength of A36 steel plate is greater than or equal to 250MPa, the tensile strength is 400-550MPa, and the elongation is ≥20%.
  2. Its carbon content is low, usually below 0.18%, which makes the steel plate have good weldability and can be connected into complex structures through common welding methods. In addition, A36 steel plates are very malleable and easy to cut, bend and shape, making them suitable for a variety of construction projects.
  3. In addition, its mechanical properties are excellent and it is suitable for use in structures under various loading conditions. It has a certain yield strength and tensile strength and can withstand larger loads.
  4. A36 steel plate has moderate hardness, is not easy to wear, and has certain wear resistance. This kind of steel plate also has good chemical properties and has good corrosion resistance for steel with a carbon content of less than 0.25%. This makes it resistant to oxidation and corrosion to a certain extent, making it suitable for use outdoors and in humid environments.

Application:

This type of steel plate is also suitable for riveting, bolting and welded structures in bridges and buildings, as well as general-purpose structural steel quality carbon steel sections, steel plates and bar steel.

In short, A36 steel plate is a low-carbon structural steel plate with good weldability, plasticity and mechanical properties, and is suitable for various construction and engineering projects.
