What is AR400 Steel Plate?

AR400 steel plate is a type of abrasion - resistant steel. It is widely used in various industries. The "AR" stands for abrasion resistant. This steel plate is known for its high hardness and toughness, which makes it ideal for applications where there is a lot of wear and tear. For example, in mining equipment, it can be used to make parts like buckets and conveyor belts that are constantly in contact with rough materials. In construction, it can be used for parts of heavy - duty machinery that need to withstand a lot of friction.

AR400 Steel Plate Specifications - Hardness

The hardness of AR400 steel plate is an important specification. It typically has a Brinell hardness number (BHN) in the range of 360 - 440. This high hardness is what gives it its excellent abrasion - resistant properties. It can resist scratches, gouges, and other forms of wear much better than regular steel. For instance, if you were to use a regular steel plate in a mining operation where rocks are constantly hitting the surface, it would quickly get damaged. But AR400 steel plate can withstand this kind of abuse for a much longer time.

AR400 Steel Plate Specifications - Chemical Composition

The chemical composition of AR400 steel plate also plays a crucial role in its properties. It usually contains elements like carbon, manganese, silicon, phosphorus, and sulfur. The carbon content is relatively high, which contributes to its hardness. Manganese helps in increasing the strength and toughness of the steel. Silicon is added to improve the steel's resistance to oxidation. Phosphorus and sulfur are present in small amounts, and their levels are carefully controlled to ensure the quality of the steel. For example, too much sulfur can make the steel brittle.

AR400 Steel Plate Specifications - Thickness

AR400 steel plate comes in different thicknesses. The thickness can range from a few millimeters to several inches, depending on the specific application. In some cases, for lighter - duty applications like small parts in a manufacturing plant, a thinner AR400 steel plate may be used. However, for heavy - duty applications such as in large mining trucks or construction equipment, a thicker plate is required to provide the necessary strength and abrasion resistance. For example, a conveyor belt in a large - scale mining operation may require a thicker AR400 steel plate to ensure it can handle the weight and abrasion of the materials being transported.

AR400 Steel Plate Specifications - Tensile Strength

The tensile strength of AR400 steel plate is another important specification. It has a relatively high tensile strength, which means it can withstand a significant amount of pulling or stretching force without breaking. This is important in applications where the steel plate may be subjected to dynamic loads. For example, in a construction crane, the parts made of AR400 steel plate need to be able to withstand the forces when lifting heavy objects. The tensile strength of AR400 steel plate is typically in the range of [X] to [Y] megapascals, depending on the exact composition and manufacturing process.

Questions and Answers

Question 1: What are the main applications of AR400 steel plate?Answer: AR400 steel plate is mainly used in industries with high abrasion requirements, such as mining (for parts like buckets and conveyor belts) and construction (for parts of heavy - duty machinery).

Question 2: How does the chemical composition of AR400 steel plate affect its properties?Answer: The carbon content gives it hardness, manganese increases strength and toughness, silicon improves oxidation resistance, and controlled amounts of phosphorus and sulfur ensure quality as too much sulfur can make it brittle.
