High Manganese Steel Plates – Work-Hardening Steel Built for Impact and Abrasion High Manganese Steel Plates, commonly known as Hadfield Steel, are designed to deliver exceptional impact strength and wear resistance. Containing 11–14% manganese, these plates have a unique property — they become harder when subjected to repeated impact or abrasion. This makes them ideal for high-stress, high-impact industrial environments. Unlike conventional wear plates that degrade over time, manganese steel improves its surface hardness under load while maintaining its core toughness. This self-hardening behavior results in extended service life and reduced downtime, especially in crushing, mining, and rail industries. Key Advantages: Hardens on impact – ideal for aggressive applications Tough, ductile, and crack-resistant under repeated stress Maintains non-magnetic properties even after work-hardening Withstands high levels of shock and gouging Can be welded and fabricated with proper precautions Typical Composition (%): Element Typical Range Manganese (Mn) 11.00 – 14.00 Carbon (C) 1.00 – 1.40 Silicon (Si) ≤ 0.40 Phosphorus (P) ≤ 0.07 Sulfur (S) ≤ 0.03 Iron (Fe) Balance Mechanical Properties: Property Value Range Tensile Strength 800 – 1000 MPa Yield Strength 350 – 500 MPa Elongation ≥ 30% Hardness ~200 BHN (as rolled), work-hardens up to 550 BHN Where It’s Used: Crusher liners, hammers, and impact walls Railway track work, points, and crossings Earthmoving and heavy mining machinery Buckets, chutes, and impact plates in cement plants Shredders, recycling equipment, and heavy-duty wear parts Summary: If your operations demand a material that strengthens under pressure, High Manganese Steel Plates are the ideal solution. With a unique ability to resist wear through work-hardening, they are built to thrive in the harshest environments — reducing replacement frequency and improving long-term efficiency.
