Mangalloy (also called mangalloy steel, manganese steel, or Hadfield steel), the only wear-resistant steel alloy found in the world, combines excellent wear properties with outstanding workability. Invented over a hundred years ago, mangalloy steel continues to be used in a wide variety of industrial applications, such as rock crushers, railway switches, and more.
Mangalloy steel is an austenitic steel alloy. It is composed of both iron and manganese, and is extremely hard, very tough, and extremely wear-resistant, with a Brinell hardness of anywhere from 350 to 500. The properties of manganese steel depend on its composition and its microstructure. Mangalloy steel is made up of austenite, which provides good ductility and toughness, and ferrite, which provides the wear-resistance. The manganese content of mangalloy steel can range anywhere from 11 to 15 percent.
Mangalloy steel is also known for being highly resistant to shock or impact. It is highly impact resistant, and its properties only improve with temperature. This makes it ideal for applications where parts endure counter-flow wear and a high level of impact, like mining and rock crushers. Additionally, mangalloy steel is highly resistant to abrasion and can be frozen and thawed without loss of performance. Furthermore, once it is heated, it can be cooled rapidly and will not lose its temper.
The most recognizable application of mangalloy steel is in track switches and related components of heavy rail systems, such as points and crossings. This is because the steel is incredibly resistant to wear and fractures, while still being malleable and able to withstand shock.
In addition to its well-known use in the rail industry, mangalloy steel is also extensively used in various types of bearings. This includes everything from ball bearings, roller bearings, and tapered bearings. Its wear and shock resistance make mangalloy steel an ideal material for many types of bearings, and its cost-effectiveness also makes it a go-to material for a variety of industrial applications.
Another common use for mangalloy steel is in cement plants. This is because the steel is highly resistant to abrasion, which is obviously important in a setting where machines and other parts must withstand a consistent level of stress from grinding and other abrasive processes such as sand or gravel.
Due to its extreme hardness and high impact resistance, mangalloy steel can also be used in the manufacture of knives, agricultural implements, and even military hardware. It can also be used to make lightweight springs, agricultural implements, umbrella ribs, and even golf clubs.
Mangalloy steel is incredibly versatile and can be used in all manner of applications, from rail switches, to bearings, to knives, to golf clubs. It can be found in a wide range of products and industries due to its extreme wear-resistance, impact resistance, and malleability.
