What is AR450 Steel?

AR450 steel is an abrasion-resistant plate steel that is designed to deliver superior toughness and strength. It has a nominal hardness of 450 BHN (Brinell Hardness Number), which indicates its excellent resistance to wear and tear. The composition typically includes a balance of carbon and alloying elements, which contribute to its increased hardness and strength.

Understanding AR450 Steel Tensile Strength

Tensile strength is a critical property that defines a material’s ability to withstand tension without failing. In the case of AR450 steel, the tensile strength generally ranges between 170 to 200 ksi (kilo-pounds per square inch). This high level of tensile strength makes AR450 steel a preferred choice for industries involving heavy equipment and machinery.

Factors Influencing Tensile Strength

The tensile strength of AR450 steel can be affected by several factors, including:
