General Info About A572-50 Hot Rolled Flats

ASTM A572-50 steel is high-strength, low-alloy structural steel. It is commonly used in construction due to its high strength-to-weight ratio. It is also used to build heavy machinery and construction equipment for this same reason.

This steel has many applications including bridges, buildings, freight cars, and more. Its high strength-to-weight ratio means less steel can be used to hold the same amount of weight, meaning it is high value.

A572-50 steel is less formable than other grades of A572, but for the most part it has good formability, weldability, and machinability. It has excellent ductility due to its chemical composition, and is very resistant to corrosion.

More Details About A572-50 Hot Rolled Flats

  • Advantages/Disadvantages

    Since A572-50 steel is a low-alloy, high-strength steel it is very strong while also being lightweight. This means that this steel has many advantages for construction with some minor disadvantages.

    • Advantages:
      • Excellent ductility is a characteristic of A527-50 because of the manganese and chromium found in it.
      • A527-50 steel has a high strength-to-weight ratio.
      • ASTM A572-50 resists corrosion due to the presence of columbium and vanadium.
    • Disadvantages:
      • This steel is somewhat more difficult to form when compared to other grades due to less carbon being present.
      • A527-50 is more difficult to cold form meaning it requires more force than plain carbon steel.
  • Industries

    Due to A572-50’s high strength-to-weight ratio, it is commonly used in the construction industry. It is efficient steel that saves money for companies that need more strength with less product. It is also commonly used in construction equipment and heavy machinery due to its strength.

  • Applications

    A572-50 steel has many valuable characteristics that make it popular in many different applications. Some applications include bridges, buildings, construction equipment, freight cars, machinery, vehicle parts, transmission towers, and more.

  • Machining

    While A572-50 steel may be harder to machine than some grades, it is still more easily formed and machined than others. It has high manganese content making it less brittle. Less brittle steel is easier to machine.

  • Welding

    Much like machining, A57250 steel may be less weldable when compared to other grades of the same steel, but it is relatively easy to weld in general. Since it is used in construction applications, it is often welded, bolted, and riveted in many different structures.

  • Heat Treatment

    A572-50 hot rolled steel can be heat treated but it is not required. Doing so can achieve a higher level of strength through the right specifications, such as quench and tempered steel plates.

Frequently Asked Questions

  • What is the difference between A36 and A572 steel?


    A572 steel has more manganese in its chemical composition than A36 steel. A572 steel has a higher ultimate tensile strength than A36 steel. A36 steel can be used to construct cars while A572 steel is used for more constructional applications.

  • What does grade 50 refer to?


    Grade 50 refers to the grade of steel based on chemical compositions and properties. This is usually based on the amount of carbon and other alloying elements found in the steel. Grade 50 steel is a high-strength, low alloy steel. It is best used when there needs to be more strength per unit of weight.

  • Is ASTM A572 hot rolled?


    Cold rolling ASTM A572 steel is more difficult because it requires more force than plain carbon steel. ASTM A572 is typically hot rolled.

  • What is hot rolled flat steel?

    Hot rolled flat steel is steel cut into long, thin strip-like pieces that have been through the hot rolling process. The hot rolling process is a three step process. It starts with the slab or billet of raw steel. That billet is then heated so that it becomes more easily bendable. Then it is rolled out into a thinner metal sheet while it is still hot. This sheet is then cut into long, skinny pieces to become hot rolled flat steel.
