General Info About A529-50 Hot Rolled Flats

ASTM A529 steel is high strength, mild carbon manganese steel. It is typically used for structural purposes in construction and civil engineering. It is commonly used in the manufacture of riveted and bolted structures due to its machinability, and it is relatively easy to weld. Heating and thermal treatment is recommended to increase strength.

Other properties include good corrosion resistance, ductility, and high strength. Common applications include structural parts for bridge support components, high rises, framing for machinery, equipment, ceilings, and walls. It can also be used in machine tracks and as warehouse supports.

More Details About A529-50 Hot Rolled Flats

  • Advantages/Disadvantages


    • ATSM A529-50 is high strength steel.
    • A529-50 steel has great corrosion resistance.
    • A529-50 has good ductility.


    • ATSM A529 steel has some limited weldability and cannot be oxy-fuel welded.
  • Industries

    A529-50 steel is typically used in construction and civil engineering due to its strength. It is great for structural components of buildings, bridges, and more.

  • Applications

    Due to ATSM A529-50’s high strength, it is typically used for structural purposes. It is used in the manufacture of riveted, bolted, and welded structures. For example, in bridge components, high rises, framing for machinery, equipment, ceilings, and walls. It can also be used as machine tracks and warehouse supports.

  • Machining

    ASTM A529-50 steel is great for machining. The high amount of manganese in this steel make machinability easy. It is commonly used in the manufacture of riveted and bolted structures.

  • Welding

    A529-50 steel is able to be welded, but it is not as easily weldable as steel with lower carbon contents. It cannot be oxy-fuel welded. You are able to weld A529-50 steel with other common welding techniques.

  • Heat Treatment

    A529-50 steel is heat treatable, and it is usually recommended for this grade of steel. Precipitation or aging treatment significantly impacts strength, but A529-50 steel is still one of the most widely used precipitation hardening grades.

Frequently Asked Questions

  • What is ASTM A529?


    ASTM A529 steel is a high-strength, mild carbon manganese steel used for structural purposes. It has good corrosion resistance and ductility while being very tough. It is popular structural steel for support components in bridges, buildings, and machinery.

  • What is steel grade 50?


    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. This means that less material can be used when meeting strength requirements.

  • What is the difference between a529 vs a572?


    A529 and A527 steel are very similar, but A529 has a slightly lower carbon content and higher ultimate tensile strength. A529 possesses an ultimate tensile strength of 72,500 pounds per square inch, while A572 has an ultimate tensile strength of 60,200 psi.
