AR400 steel, prized for its resistance to abrasion, finds widespread application across various industries where durability is paramount:

  1. Mining and Quarrying: AR400 is integral to mining machinery such as dump trucks and excavator buckets, enduring the abrasive onslaught of rocks and gravel.
  2. Construction: In construction equipment like backhoe buckets and crushers, AR400’s resilience tackles the wear and tear of handling harsh materials on site.
  3. Material Handling: From chutes to liners, AR400 steel fortifies material handling systems against abrasion, reducing maintenance needs and extending equipment life.
  4. Aggregate Processing: Crushers, screens, and hoppers in aggregate processing rely on AR400’s durability to withstand the punishing impact of materials.
  5. Forestry: AR400 components in forestry equipment endure the rigors of log splitters, grapples, and mulchers, facing abrasion from wood and debris.
  6. Transportation: AR400 reinforces transportation equipment such as trailers and truck beds, standing up to the abrasion of loading and unloading materials.
  7. Recycling: In recycling facilities, AR400 resists wear in shredders, sorting equipment, and conveyors, handling materials like scrap metal and plastics.

AR400 steel serves as a stalwart against abrasion, fostering longevity and reliability in diverse industrial applications.

Comparing AR Plate (AR400) and Mild Steel: Strengths, Workability, and Applications


  • AR400: Imagine AR400 as a sturdy shield, ready to fend off scratches and heavy wear from tough jobs.
  • Mild Steel: Mild steel is like a reliable tool, sturdy but not built for enduring intense scratching or rubbing.


  • AR400: It’s tough enough to handle heavy-duty impacts and usage, though it’s not the absolute strongest material available.
  • Mild Steel: Strong enough for everyday tasks, but not as resilient as AR400 when it comes to extreme wear and tear.

Ease of Working With:

  • AR400: Working with AR400 can be a bit challenging, especially during welding, and may require some special handling.
  • Mild Steel: It’s straightforward to weld and shape without much difficulty.


  • AR400: Because of its toughness and durability, AR400 tends to be pricier.
  • Mild Steel: More budget-friendly compared to AR400.

Where You’ll Find Them:

  • AR400: Used in places where heavy rubbing and scraping occur, like on bulldozer blades or conveyor belts.
  • Mild Steel: Found in a wide range of everyday items, from cars to construction materials to kitchen appliances.

So, if you need something to withstand heavy wear and tear, go for AR400, but if you’re looking for something sturdy at a lower cost, mild steel is the way to go.
