High Hardness Abrasion Resistant Plate AR500 Steel Plate

AR500 wear-resistant steel plate is a martensitic wear-resistant steel with a Brinell hardness of 470-544 HBW, exhibiting excellent wear resistance and good impact toughness. This high-hardness steel plate, obtained through quenching and tempering processes, boasts a service life more than five times that of ordinary structural steel under harsh working conditions in mining machinery, engineering equipment, and material handling systems. It has been widely used in excavator buckets, crusher liners, dump truck bodies, and other components.

Here are some common applications of AR steel plates：

• Conveyors
• Buckets
• Dump liners
• Construction attachments, such as those used on bulldozers and excavators
• Grates
• Chutes
• Hoppers

AR500 steel plate

AR material is produced by quenching and tempering forged steel blocks, or ingots. During this process, the grain structure is changed to increase toughness and encourage formability (or, to be less brittle), and results in through-hardening of the material.

Quenching and tempering (Q&T) is a two-part process:

 Quenching occurs when steel brought to a high temperature – usually between 1,500-1,650-degrees Fahrenheit – is rapidly cooled with water. This process causes crystal structures to form within the steel, increasing hardness.

 Tempering is the process of re-heating quenched steel to a below-critical temperature (around 300-700-degrees Fahrenheit), and then allowing the plate to cool in normal air temperatures.

Reheating the material breaks down the crystal structures formed during the quenching process, while the long cooling allows the crystal structures to refrom – maintaining most of the strength and hardness, but adding to overall ductility.

FAQ:

1.What is the hardness of AR500 steel plate?

Much like AR450 and AR400, AR500 steel is a specific type of abrasion resistant steel with a surface hardness of 477-534 BHN. It is a high-carbon steel alloy that provides greater impact and sliding abrasion resistance by comparison.

2.What is AR500 material equivalent to?

AR500 steel plate is chemically similar to AR400 steel plate, except the hardness range is higher and it has more carbon and manganese than AR400. These elemental differences help the steel achieve a higher surface hardness. To be classified as AR500, the hardness needs to clock in between 477 BHN and 550 BHN.

3.Is AR500 the same as Hardox 500?

One of the most significant differences is their hardness level. Hardox grades usually range from 400 to 600, while AR500 has a hardness level 500. Hardox has high toughness and tensile strength and can handle a wide range of extreme temperatures compared to AR500.
