High-manganese steel lining plates, also known as SAG mill liners, are critical components in industrial machinery designed to withstand extreme wear and impact. These liners are engineered to protect equipment in harsh environments, ensuring longevity and operational efficiency. Shijiazhuang Chengda Wear Resistant Materials Co., Ltd. has established itself as a leader in providing high-quality high-manganese steel solutions, leveraging advanced materials science to meet the demands of modern industries.
High-manganese steel is renowned for its unique combination of strength and toughness. Its chemical composition typically includes 10%-15% manganese and 0.90%-1.50% carbon, with carbon content often exceeding 1.0%. This composition allows the steel to rapidly harden on the surface when subjected to severe impact or contact stress, while maintaining a tough core. This dual property makes it ideal for applications where wear resistance and impact resistance are paramount.
One of the standout advantages of high-manganese steel is its ability to undergo secondary surface hardening after initial wear. This means that even after prolonged use, the material continues to offer enhanced protection, reducing the need for frequent replacements. The material's safety and reliability make it a preferred choice in critical environments such as mining, metallurgy, and military applications.
The following table outlines the key technical specifications of high-manganese steel lining plates:
| Parameter | Details |
|---|---|
| Chemical Composition | Manganese: 10%-15%; Carbon: 0.90%-1.50% |
| Hardness (Surface) | Approx. 220-300 HB |
| Toughness (Core) | High impact resistance |
| Wear Resistance | Excellent, with secondary hardening capability |
| Operating Temperature Range | -20°C to 400°C |
High-manganese steel lining plates are widely used in industries that demand robust and durable materials. Mining and metallurgy are primary sectors where these liners are employed to protect equipment from abrasive materials and high-impact forces. In quarrying and coal mining, the material's resistance to wear ensures minimal downtime and maintenance costs.
The versatility of high-manganese steel extends beyond traditional industries. It is increasingly being applied in cutting-edge fields such as magnetic levitation trains and rock drilling robots, where its ability to withstand extreme conditions is crucial. Additionally, its use in military equipment highlights its reliability in high-stakes environments.
