High manganese plate, also known as Hadfield steel, is a type of alloy steel containing a high percentage of manganese, typically around 12-14%. This high manganese content gives the plate exceptional toughness, hardness, and resistance to wear and impact, making it ideal for heavy-duty applications. The steel's unique property is that it hardens under impact and strain, making it suitable for use in environments with high abrasion and heavy impact. High manganese plates are commonly used in industries such as mining, construction, and engineering for applications like crusher liners, hoppers, chutes, and other equipment that requires high durability and resistance to wear.
