Abrex 400, also known as Rockstar 400, is a high-strength and abrasion-resistant steel plate designed for applications in harsh industrial environments where wear and tear are significant challenges. These plates are manufactured to offer exceptional durability and resistance to abrasion, making them suitable for various industries such as mining, construction, material handling, and agriculture.
The "400" in Abrex 400 / Rockhard 400 signifies the Brinell hardness number, which is a measure of the hardness of the steel. In this case, a Brinell hardness of 400 indicates a high level of hardness, making the steel highly resistant to abrasion and wear. This property is crucial in applications where the material is subjected to sliding or impact abrasion, such as in the mining of ores or handling of bulk materials
One of the key features of Abrex 400 Plates is their toughness, which is a result of a combination of high hardness and good ductility. This balance of properties allows the plates to withstand heavy impact and resist deformation, contributing to their longevity in service. The plates are also weldable, which adds to their versatility in various fabrication processes.

The manufacturing process involves quenching and tempering, which enhances the hardness and strength of the steel. This heat treatment process contributes to the formation of a martensitic microstructure, providing the necessary hardness for abrasion resistance.
Rockstar 400 Plates typically have a uniform thickness and flatness, making them easy to work with in fabrication processes such as cutting, welding, and forming. These plates can be customized to meet specific requirements and dimensions, offering flexibility in design and application.
In addition to abrasion resistance, Abrex 400 Plates exhibit good corrosion resistance, which is crucial for applications in corrosive environments. This corrosion resistance is achieved through the addition of alloying elements like chromium and nickel in the steel composition.
The longevity and performance of Hardox 400 Plates make them a cost-effective solution in the long run, as they reduce downtime and maintenance costs associated with wear and abrasion. Industries that deal with abrasive materials or processes requiring resistance to wear and impact often prefer Abrex 400 plates for their reliability and durability.
