High Manganese Steel Liner | SAG Mill Liner | Shijiazhuang Chengda

High-manganese steel lining plates, also known as SAG mill liners, are engineered to withstand extreme industrial conditions. Developed by Shijiazhuang Chengda Wear Resistant Materials Co., Ltd, these products combine exceptional strength and toughness to address challenges in mining, metallurgy, and heavy machinery. This article explores their features, advantages, technical specifications, and applications, supported by authoritative references from the National Institute of Standards and Technology (NIST).

Understanding High-Manganese Steel: A Revolutionary Material

High-manganese steel, or Hadfield steel, is a unique alloy with a chemical composition of 10%-15% manganese and 0.90%-1.50% carbon. This combination gives it unparalleled resistance to impact and abrasion. Unlike conventional steels, high-manganese steel undergoes surface hardening under severe stress, maintaining a tough core while developing a durable outer layer. This property makes it ideal for environments where wear and tear are constant threats.

According to NIST research, high-manganese steel's mechanical properties are critical in applications requiring high fatigue resistance and impact strength. The material's ability to self-harden under stress ensures longevity, reducing the need for frequent replacements. This characteristic is particularly valuable in industries like mining, where equipment is subjected to relentless mechanical forces.

Key Features of High-Manganese Steel Liners

Shijiazhuang Chengda's high-manganese steel liners are designed with precision to meet the demands of modern industrial operations. Key features include:

• Exceptional Wear Resistance: The alloy's surface hardening capability minimizes material degradation under heavy loads.
• High Impact Strength: Engineered to absorb and distribute energy from collisions and extrusion forces.
• Corrosion Resistance: The manganese content enhances resistance to chemical and environmental wear.
• Long Service Life: Secondary surface hardening extends the product's lifespan, reducing maintenance costs.

These features make high-manganese steel liners a preferred choice for ball mills, sag mills, and other grinding equipment where durability is paramount.
