Product Description
AISI 8620 Round Bar
Introduction:
AISI 8620 is a versatile, low-alloy steel that is widely recognized for its superior case-hardening properties, excellent toughness, and high wear resistance. It is commonly used in producing critical components requiring surface hardness combined with a tough and ductile core, making it ideal for automotive, industrial, and engineering applications.
Key Features and Benefits
-
Case-Hardening Capability:
- AISI 8620 can be carburized to provide a hard, wear-resistant surface while maintaining a tough inner core.
-
High Toughness:
- The steels inherent toughness ensures reliable performance under dynamic and impact loading.
-
Excellent Machinability:
- Easy to machine in its annealed condition, facilitating precision manufacturing of complex components.
-
Good Weldability:
- Can be welded effectively with appropriate pre-heating and post-weld heat treatment.
-
Heat-Treatment Flexibility:
- Responds well to carburizing, hardening, and tempering processes, allowing customization for specific applications.
-
Wear Resistance:
- The carburized layer provides exceptional wear resistance, prolonging component life.
