Understanding the Difference: AR 400 vs. AR 500 Steel Plates

AR 400 and AR 500 steel plates represent two premier grades of abrasion-resistant steel designed to withstand severe wear and abrasion challenges found in even the harshest conditions. Crafted with precision, these steel variants are tailored to offer superior resistance against abrasion-induced deterioration when used across various industries.

  • In mining, AR 400 and AR 500 steel plates are used for heavy machinery components, shoots, conveyors and ore pockets.
  • On construction sites, they are used in earth moving and material handling equipment.
  • In the agriculture sector, AR 400 and AR 500 steel plates are widely used to ensure the machinery endures the abrasive effects of soil and crop debris, maintains equipment integrity and operational efficiency.

But what are the main differences between these two grades of steel and how do they affect their applications? Let&#;s dive deeper into what sets AR 400 and AR 500 steel plates apart.

The Main Distinctions between AR 400 and AR 500 Steel Plates

Hardness

  • AR 400 Steel: This grade has a nominal hardness of 400 Brinell (HB), which measures the hardness of materials. It&#;s suitable for applications where moderate to heavy wear resistance is required, such as in mining, construction, and material handling equipment.
  • AR 500 Steel: This grade has a higher nominal hardness of 500 Brinell, making it harder and more resistant to wear than AR 400. It&#;s typically used in applications where extreme abrasion resistance is necessary, such as in shooting targets,

    armored vehicles

    , and mining equipment.

Cracking

  • AR 400 Steel:

    Compared to AR 500 steel, AR 400 generally has higher toughness and ductility, meaning it&#;s less prone to cracking, especially in applications involving high-impact or dynamic loading conditions. However, it&#;s essential to consider that both grades of steel can still experience cracking under extreme stress or improper use.
  • AR 500 Steel:

    This grade is more prone to cracking with impact than AR 400 steel, making it more suitable for sliding abrasion found in agricultural, manufacturing, and mining machinery and equipment.

Applications

  • AR 400 Steel: Commonly used in applications where moderate abrasion resistance is needed, AR 400 steel plates can be found in dump truck bodies, crushers, hoppers, and chutes.
  • AR 500 Steel: Preferred in applications where a higher level of abrasion resistance is crucial, AR 500 steel plates are used for ballistic plates, shooting targets, and armor plating.

Machinability

  • AR 400 Steel:

    Due to its lower hardness, AR 400 steel is generally considered to be more readily machinable.
  • AR 500 Steel:

    This grade of steel is machinable but more challenging to machine compared to lower grades. It requires appropriate cutting tools, techniques, and machining parameters to achieve satisfactory results.

Weldability

  • AR 400 Steel:

    The company is the world’s best ar500 plate steel supplier. We are your one-stop shop for all needs. Our staff are highly-specialized and will help you find the product you need.

    This grade can be welded using appropriate procedures, but precautions need to be taken to avoid excessive heat input, which can affect the hardness and performance of the material.
  • AR 500 Steel:

    Using appropriate welding procedures, AR 500 steel can be welded, but care must be taken to avoid excessive heat input, which can compromise the material&#;s hardness and performance.

The Unmatched Performance of Titus Steel&#;s AR 400 and AR 500 Steel Plates

Titus Steel carries both grades of AR steel under the trade name DYNAMIC and DYNAMIC Armor.

When choosing between DYNAMIC AR 400 and DYNAMIC AR 500 steel plates, the selection will depend on the specific requirements of the application.

If your project involves high levels of sliding abrasion and wear or requires ballistic protection, DYNAMIC AR 500 is the preferred choice due to its higher hardness.

However, for less demanding applications, DYNAMIC AR 400 may provide appropriate wear resistance while being more machinable.
