austenitic manganese steel
Noun: * A type of alloy steel characterized by a high manganese content (typically 10-14%) and an austenitic microstructure at room temperature. This specific composition makes it exceptionally resistant to abrasion (wear) and impact (shock).
This is a technical term used primarily in metallurgy, engineering, and industrial contexts. It describes a material chosen for applications where extreme durability is required. * The crusher jaws were lined with austenitic manganese steel to withstand the constant impact of rocks. * Due to its work-hardening properties, austenitic manganese steel becomes harder the more it is subjected to impact.
- The term is often used interchangeably with Hadfield steel, named after its inventor Sir Robert Hadfield.
- Its key property is work hardening: the surface of the steel becomes progressively harder when subjected to impact or pressure, while the core remains tough and ductile.
- Hadfield steel (n): A common synonym for austenitic manganese steel.
- Manganese steel (n): A more general term that may refer to steels with lower manganese content; austenitic manganese steel is a specific, high-manganese variant.
- Work-hardening steel (n): A descriptive term highlighting its most important mechanical property.
- Hadfield steel
- High-manganese steel (in specific contexts)
This term is highly specific. It does not refer to all steel containing manganese, only to those with a very high percentage (around 10-14%) that results in a stable austenitic structure, granting its unique properties.
-
a steel with a relatively large component (10-14%) of manganese; highly resistant to wear and shock
