What Are AR500 Plates?
Definition and Composition
AR500 plates are strong steel plates made to last. They resist damage in tough conditions. Their hardness comes from a mix of elements. Below is a table showing what makes up AR500 plates:
| Element | Percentage Range |
|---|---|
| Carbon (C) | 0.31% - 0.38% |
| Manganese (Mn) | 0.70% - 1.20% |
| Phosphorus (P) | 0.025% (max) |
| Sulfur (S) | 0.010% (max) |
| Silicon (Si) | 0.20% - 0.35% |
| Chromium (Cr) | 0.80% - 1.10% |
This mix of elements makes AR500 plates strong and tough. They can handle extreme conditions without breaking.
Key Characteristics
Hardness and Durability
AR500 plates are very hard, rated 477 to 534 BHN. This hardness helps them handle heavy impacts without bending. They have a tensile strength of 240 Ksi and a yield strength of 215 Ksi. This makes them perfect for tough jobs and heavy use.
Abrasion Resistance
AR500 plates resist scratches and wear very well. Their even hardness keeps them working in rough places. This is why they are used in mining and construction.
Cost-Effectiveness
AR500 plates save money because they last a long time. You won’t need to replace them often. They are a good choice for their price compared to other materials.
Common Grades of AR500 Steel
AR500 plates come in different grades for various uses. Some grades are better for handling impacts. Others are made to resist wear. Pick the grade that fits your needs best.
How Are AR500 Plates Made?
Steel Alloy Composition
AR500 plates are made from a special steel mix. This mix includes carbon, manganese, and chromium. Each part helps make the steel strong and tough. Carbon makes it harder, while manganese adds strength. Chromium helps stop rust, so it lasts longer. The right mix of these elements makes AR500 plates perfect for tough jobs.
Heat Treatment Process
Heat treatment makes AR500 plates strong and durable. It has three main steps:
- The steel is heated until it becomes soft and bendable.
- It is quickly cooled to make it very hard.
- Then, it is heated again at a lower temperature to reduce stress.
For AR500 plates, exact temperatures and times are important. During tempering, the steel is heated to 200–300°C for 2–4 hours. After welding, it is heated to 200–260°C for 1–2 hours. These steps give the plates their famous strength and toughness. Heat treatment also helps them resist scratches and impacts, making them great for hard tasks.
Quality Testing and Standards
AR500 plates are tested to meet strict quality rules. ASTM A6 checks general steel requirements. ASTM E10 ensures hardness is measured correctly. Factories also test for strength and durability. Tests happen before and after making the plates, often in outside labs. These tests prove AR500 plates are ready for tough jobs and safety uses.
By following these rules, AR500 plates stay strong in rough conditions.
Key Advantages of AR500 Plates
Long Life and Scratch Resistance
AR500 plates are very strong and last a long time. Their hardness, around 500 HBW, stops scratches and dents. This makes them great for places with lots of wear. They last 15–25% longer than AR400 or AR450 plates. This means fewer replacements, saving both time and money.
AR500 plates have two layers that make them tough. The hard outer layer stops scratches, while the inside layer prevents breaking. This makes them perfect for hard jobs like mining and building.
- Hardness Comparison: AR500 is harder (477-534 BHN) than Hardox 500 (470-530 HBW).
- Tensile Strength: AR500 is stronger at 1655 MPa, so it stretches less.
- Wear Properties: AR500’s wear resistance depends on how it’s made.
Useful in Many Industries
AR500 plates work well in many fields. Their scratch resistance is great for heavy machines like bucket liners. In factories, they are used in chutes and screens, handling shaking better than other metals.
In mining, AR500 plates handle pressure in bulldozer blades and buckets. They are also used in body armor for soldiers and police. For shooting targets, they last a long time at gun ranges.
- Robotics: AR500 plates are strong enough for robot arms.
- Building Design: They can even be used as decorations in buildings.
Saves Money Over Time
AR500 plates are worth their cost. They last longer, so you spend less on replacements. While Hardox 500 may be tougher, AR500 is stronger and handles stress better. This makes them a smart choice.
Their scratch resistance adds to their value. AR500 plates work well in tough places, cutting down on repairs and delays. You can trust them to keep working when you need them most.
