How Are AR Plates Created?

Abrasion resistant steel plates (AR plates) are a critical component in many industrial applications where durability and toughness are essential. These plates are designed to withstand high levels of wear and tear, making them ideal for use in mining, construction, and manufacturing industries.

Let&#;s take a closer look at how AR plates are created, including the materials and manufacturing processes used.

What is Abrasion Resistant Steel?

Abrasion resistant steel is a specialized type of steel that is specifically designed to endure high levels of wear and tear, making it ideal for use in demanding industrial settings where robustness and resilience are essential.

Abrasion resistant steel is created by adding various alloys to the steel during the manufacturing process. These alloys help to increase the hardness and toughness of the steel, making it more resistant to abrasion and wear.

Creating AR Plates

AR plates are created using a specialized manufacturing process that involves heating and cooling the steel multiple times. The process is designed to increase the hardness and toughness of the steel, making it more resistant to abrasion and wear.

Below are the steps involved in creating AR plates:

1. Melting and Mixing

The first step in creating abrasion resistant steel plates is melting and mixing the raw materials. The raw materials typically include iron ore, coal, and limestone, as well as various alloys that are added to increase the hardness and toughness of the steel.

1. Casting

After the raw materials have been melted and mixed, the steel is cast into large slabs or billets. These slabs or billets are then heated and rolled into thinner sheets or plates.

1. Heat Treatment

Once the steel has been rolled into plates, it is subjected to a heat treatment process. This process involves heating the steel to a high temperature and then rapidly cooling it.

1. Quenching and Tempering

After the heat treatment process, the steel is quenched and tempered. Quenching involves rapidly cooling the steel to room temperature, which increases its hardness. Tempering involves reheating the steel to a lower temperature, which increases its toughness.

1. Cutting and Finishing

After the quenching and tempering process, the steel plates are cut and finished to the desired size and shape. This may involve cutting the plates to a specific length or width, or it may involve adding additional finishing touches, such as beveling or chamfering the edges.

Quenching & Tempering

Abrasion resistant steel undergoes a two-step heat treatment process called quenching and tempering, which alters the steel's grain structure to increase hardness and toughness.[2]

During the quenching phase, the steel is heated to an above-critical temperature and is then rapidly cooled with water. The steel is then re-heated to a below-critical temperature and air cooled, which is the tempering phase.[2]

Brinell Hardness

[

The hardness of abrasion resistant steel is determined by a Brinell hardness test. This test uses a small steel ball to inflict force on a material. The indentation created by the steel ball is then measured and used to calculate Brinell hardness number (BHN).[3]

Grade BHN AR200 & AR235 180-260 AR400 360-440 AR450 430-480 AR500 460-544 AR600 570-625

Standards for Brinell hardness testing are regulated by ASTM International under E10 specifications.[5]

Applications

[

edit

]

Abrasion resistant steel is typically used in applications requiring high wear resistance, including backhoe buckets and teeth, bulldozer blades, dump truck beds, ore and coal chutes, augers and aggregate conveyors.[6] Additional uses include shooting targets and armor, AR500 steel is commonly used for these applications as higher BHN steels are more brittle.[7]
