High Manganese Steel Liner | SAG Mill Liners | Shijiazhuang Chengda

High manganese steel, also known as Hadfield steel, is a specialized material renowned for its exceptional durability and performance in extreme environments. This article explores the features, advantages, technical specifications, application scenarios, and company background of high-manganese steel liner plates and grate plates, manufactured by Shijiazhuang Chengda Wear Resistant Materials Co., Ltd.

What is High Manganese Steel?

High-manganese steel is characterized by its unique chemical composition, typically containing 10%-15% manganese and 0.90%-1.50% carbon. This combination provides the material with remarkable strength and toughness. When subjected to severe impact or contact stress, high-manganese steel undergoes rapid surface hardening while maintaining a tough core. This hardness-toughness balance makes it ideal for applications involving impact loads, abrasion, and extrusion.
