What is Hadfield Steel in Welding?

Hadfield steel is austenitic manganese steel that was invented by Sir Robert Hadfield in 1882. It is known for its high impact toughness and resistance to abrasion, making it ideal for applications such as railroad tracks, crushers, and demolition tools.

While similar steels exist, none have the combination of strength and ductility that makes Hadfield steel so unique. For this reason, it is often the material of choice for welding applications. In addition to its outstanding properties, Hadfield steel is also easy to weld and work with, making it a versatile material for a variety of applications.

What is Hadfield steel used for?

Hadfield steel is most commonly used in applications where high impact toughness and wear resistance are required. Some examples include:

Railroad tracks.
Crushers.
Demolition tools.
Welding applications.

Why is Hadfield steel so unique?

Hadfield steel is unique because it has a combination of high strength and ductility that is not found in other steels. This makes it ideal for applications where both toughness and resistance to wear are required.

Hadfield steel composition

Hadfield steel is an alloy steel that contains carbon and manganese. The carbon content is typically between 0.8% and 1.2%, while the manganese content is usually between 11% and 14%. The high carbon and manganese content gives Hadfield steel its unique combination of high strength and ductility.
