Material properties

UNS J91339 is a high manganese austenitic steel known for its durability and high wear resistance, particularly in harsh working environments. This steel is characterized by its excellent ability to withstand high impact and abrasion, which makes it ideal for heavy-duty applications. Its capacity for work-hardening upon impact significantly enhances its wear resistance while maintaining good ductility and toughness. This allows for the steel to absorb energy and resist fracture, a critical property in applications involving heavy loads or sudden impact forces.

Advantage

1. High impact resistance enhances durability.
2. Work-hardens under impact, increasing wear resistance.
3. Maintains ductility and toughness under stress.
4. Resists wear and abrasion effectively.
5. Suitable for heavy-duty applications.

Application

UNS J91339 steel is predominantly used in industries requiring materials that can endure severe wear and tear. Common applications include parts for mining equipment, heavy-duty machinery components, and impact-resistant surfaces. It is also utilized in railway and tramway tracks, which are subject to constant wear and impact. Additionally, its high durability makes it suitable for crusher parts and other components where high impact resistance is critical.
