What is AR450 Steel plate?

AR450 steel plate is another type of abrasion-resistant steel similar to AR400 but with a higher level of hardness. The "AR" still stands for "abrasion-resistant," and the number 450 indicates a higher Brinell hardness number compared to AR400. AR450 steel is designed to provide even greater resistance to wear and abrasion in challenging environments.

Key properties include:

Hardness : AR450 steel typically has a hardness of around 450 Brinell, which is higher than that of AR400 steel. This increased hardness makes AR450 more suitable for applications where extreme wear resistance is required.

Toughness : DespiteLike AR400, AR450 steel possesses good toughness, allowing it to withstand impact and deformation without fracturing

Weldability : AR450 steel can be welded, but precautions are generally taken to avoid issues like cracking. Preheating and post-weld heat treatment may be necessary depending on the welding method used.

Formability : While it is harder than AR400, AR450 can still be formed and machined, though it may require more force and specialized equipment.

AR450 steel finds applications in similar industries as AR400

where high levels of abrasion resistance are crucial. Common applications include

Mining equipment : AR450 is used for components like buckets, liners, and screens in mining equipment.

Construction equipment : Parts exposed to abrasive materials, such as bulldozer blades and excavator buckets, may be made from AR450 steel.

Material handling : AR450 is suitable for use in conveyor systems, chutes, and hoppers where materials with high abrasiveness are transported.

Aggregate processing : Equipment involved in crushing and processing aggregate materials may utilize AR450 steel to resist wear.

Choosing between AR400 and AR450 depends on the specific requirements of the application. AR450 is generally selected for situations where a higher level of hardness and abrasion resistance is necessary. However, it's essential to consider factors like impact resistance, corrosion resistance, and cost when selecting the appropriate material for a given application.

Steel plate Sizes

Steel Warehouse can supply the following sizes of AR450 Steel:

.25”-0.315” thickness offered in 48”- 65” wide, cut to your requested length
.375”-2.00” thickness offered in standard sizes (96” x 240”/288”)

Properties

AR450 steel is one of the more abrasion resistant steels available. As you increase hardness, however, you are creating a more rigid steel. This means that AR450 is less weldable and formable than other types of AR steel.

AR450 has the following chemical and mechanical properties:

Welding = Decent
Machining = Good
Abrasion Resistance = Excellent
Corrosion Resistance = Good
Forming = Fair

Steel Requirements

AR450 meets ASTM E10 standards for mechanical properties. The flatness and thickness standards are also 50% of that specified in ASTM A-6 with special tolerances available..

Benefits of AR450

The main benefit of AR450 steel plate, like any abrasion resistant steel, is its ability to resist wear and abrasion. Because of this, it can lead to less down time and can improve the longevity of your equipment by reducing erosion and wear. All of this, in turn, can lead to maximized production time.
