Manganese Plates

Manganese plates are flat sheets of steel that are alloyed with manganese, a chemical element known for its high strength, toughness, and abrasion resistance. It has a high tensile strength, making them resistant to bending, twisting, and breaking under heavy loads.

  • Offers high hardness
  • Resistant to wear
  • Abrasion resistance
  • Good ductility
  • Impact and shock resistance
  • Good corrosion resistance
  • Low magnetic permeability

Thermal Heat Treatment

Manganese plates are typically quenched and tempered for thermal treatment. The quenching process involves rapidly cooling the steel from a high temperature, such as in a water or oil bath. This rapid cooling helps to harden the steel and improve its strength and toughness.


Manganese plates are generally considered to have good formability, but their high strength and hardness may require more force and power during forming operations compared to lower strength materials.


Manganese plates can be welded using a variety of techniques, but proper preparation and precautions are necessary to ensure the weld quality and prevent damage to the material.

Different Grades

  • 3401
  • 16MN
  • X120Mn12
  • GX120Mn12
  • ASTM 128 Grade B2


Manganese plates offer a number of advantages over other types of materials, including:

  • Manganese plates have a high strength-to-weight ratio, making them suitable for applications where strength is important but weight needs to be minimized.
  • It has excellent wear resistance, making them suitable for use in applications where abrasion and impact resistance are critical, such as in mining, construction, and industrial equipment.
  • Our manganese plates have a high level of toughness, meaning they are able to absorb energy without fracturing or breaking, making them suitable for use in applications that require resistance to shock and vibration.
  • Guaranteed our manganese plates are relatively easy to machine and can be worked into complex shapes using standard machining techniques.
