High Manganese Steel Plate – Work-Hardening Wear-Resistant Steel High Manganese Steel Plates are alloy steels containing around 11–14% manganese, known for their unique work-hardening properties and exceptional toughness. These plates become harder and more wear-resistant when subjected to impact or abrasion, making them ideal for severe wear environments. Unlike other steels, high manganese steel does not wear out but hardens under stress, providing extended service life. Even in extremely abrasive conditions, it retains its ductility and shock resistance without cracking or breaking. Key Features: Excellent work-hardening ability – hardens with repeated impact Outstanding resistance to abrasion and high-impact loads Good weldability and machinability with special techniques Retains toughness and ductility even when hardened Magnetic in nature with high tensile strength Typical Chemical Composition: Element Content (%) Manganese 11.0 – 14.0 Carbon 1.0 – 1.4 Silicon 0.3 – 1.0 Iron Balance Mechanical Properties: Property Value Tensile Strength 850 – 1000 MPa Yield Strength Approx. 350 MPa Hardness (as-delivered) 200 BHN (can harden to 500 BHN) Elongation ≥ 30% Common Applications: Earthmoving and mining equipment (e.g., shovel liners, crusher jaws) Railway trackwork and switches Construction and demolition tools Shot blasting and impact-resistant parts Quarries and material handling systems Summary: High Manganese Steel Plates are designed for extreme wear and impact resistance. They are widely used in industries where abrasion, impact, and high-pressure conditions demand a steel that becomes stronger with use, ensuring long life and reduced downtime.
