High Manganese Plate – Impact-Tough Wear-Resistant Alloy High Manganese Plates, also known as Hadfield steel plates, are specially engineered for extreme abrasion and impact conditions. With a manganese content of 11–14%, the material possesses a unique ability to harden when struck or stressed, making it stronger the more it is used. This property makes the steel highly suitable for dynamic environments where conventional steels would wear out quickly. It maintains high ductility and impact strength even in its hardened state, ensuring exceptional service life and performance. Salient Features: Develops high surface hardness through impact (up to 500 BHN) High resistance to abrasion, friction, and repeated impact Maintains toughness without cracking or breaking Can be cut, welded, and fabricated with care High tensile and elongation values for dynamic applications Typical Composition Profile: Component Range (%) Mn (Manganese) 11 – 14 C (Carbon) 1.0 – 1.4 Si (Silicon) 0.3 – 1.0 Fe (Iron) Balance Mechanical Characteristics: Property Specification UTS (Tensile Strength) 850 – 1000 MPa Yield Strength ~350 MPa Elongation 30% and above Surface Hardness Starts at ~200 BHN, hardens to 500 BHN Main Uses: Crusher hammers, liners, and jaw plates Rail crossings and track components Heavy machinery wear parts Impact areas in mining and quarrying Shot blast and surface processing zones Conclusion: High Manganese Plates are self-hardening, high-strength, and high-impact-resistant steels ideal for industries dealing with intense wear and repeated mechanical force. Their long service life and superior strength make them a cost-effective and reliable choice in the harshest working conditions.
