Abrasian & Wear Resistant Steel Plates
Abrasion Resistant (AR) steel plate is typically made in the as-rolled condition. These types/grades of steel plate products have been developed specifically for long service life in harsh conditions. AR products are suitable for a variety of applications in areas such as mining/quarrying, conveyors, material handling and construction, and earthmoving. esigners and plant operators choose AR plate steel when striving to extend service life of critical components, and reduce the weight of each unit put into service. The benefits of employing wear-resistant plate steel in applications involving impact and/or sliding contact with abrasive material are immense. Wear resistant steel pates is used in areas where there is likely to be a high degree of abrasion or wear of the steel plate. Steels with a high HB rating (Brinel Hardness) are intended for applications where wear or abrasion resistance is important. The benefit of using an abrasion resistant steel is that that the plant, machinery or constructions working life can be extended considerably. This can significantly improve the reliability, durability and safety of structures and Equipment.

Manufacturing Process
The production of Carbon Steel Abrasion and Wear Resistant Steel Plates involves a meticulous manufacturing process designed to ensure durability and strength. The process begins with the selection of high-quality raw materials, followed by precision alloying to achieve optimal carbon and hardness levels. Through advanced techniques like quenching and tempering, the steel undergoes controlled heating and rapid cooling to enhance its toughness and wear resistance. The plates are then rolled and cut to the specified dimensions, maintaining strict adherence to international standards. Finally, rigorous quality checks and testing are conducted to ensure each steel plate meets the highest performance criteria for demanding applications.
