High-Manganese Steel Liner | Shijiazhuang Chengda | Wear Resistance & Impact Strength

Shijiazhuang Chengda Wear Resistant Materials Co., Ltd. has established itself as a leader in the development and production of high-manganese steel lining plates, also known as SAG mill liners and ball mill liners. These advanced materials are engineered to withstand extreme conditions in industries such as mining, metallurgy, and construction. This article explores the technical specifications, key advantages, and diverse applications of high-manganese steel linings, while also highlighting the company's commitment to innovation and quality.

Understanding High-Manganese Steel: A Material of Exceptional Durability

High-manganese steel, commonly referred to as Hadfield steel, is a unique alloy characterized by its high manganese (10%-15%) and carbon (0.90%-1.50%) content. This combination of elements grants the material unparalleled strength and toughness, making it ideal for applications involving severe impact loads and abrasive environments.

One of the most remarkable properties of high-manganese steel is its work-hardening capability. When subjected to impact or contact stress, the surface of the steel rapidly hardens, while the core retains its exceptional toughness. This dual characteristic ensures excellent wear resistance and impact protection, even after prolonged use. According to the National Institute of Standards and Technology (NIST), such materials are critical for high-stress industrial applications where traditional alloys would fail under similar conditions (NIST, 2023).
