AISI 8620 Round Bar

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

1. Case-Hardening Capability:

   • AISI 8620 can be carburized to provide a hard, wear-resistant surface while maintaining a tough inner core.

2. High Toughness:

   • The steel™s inherent toughness ensures reliable performance under dynamic and impact loading.

3. Excellent Machinability:

   • Easy to machine in its annealed condition, facilitating precision manufacturing of complex components.

4. Good Weldability:

   • Can be welded effectively with appropriate pre-heating and post-weld heat treatment.

5. Heat-Treatment Flexibility:

   • Responds well to carburizing, hardening, and tempering processes, allowing customization for specific applications.

6. Wear Resistance:

   • The carburized layer provides exceptional wear resistance, prolonging component life.

• Yield Strength: ‰370 MPa
• Elongation: ‰16%
• Hardness (after Carburizing): 60“63 HRC (surface)

Applications

1. Automotive Industry:

   • Used in manufacturing gears, crankshafts, camshafts, and pinions requiring high wear resistance.

2. Power Transmission Components:

   • Ideal for shafts, couplings, and other parts subjected to torsional stress.

3. Heavy Machinery:

   • Commonly employed in bushings, axles, and rollers due to its durability and toughness.

4. Aerospace Industry:

   • Suitable for components such as landing gear and structural parts requiring a balance of strength and ductility.

5. General Engineering:

   • Widely used for making tools, dies, and fixtures for industrial applications.

Heat Treatment Processes

1. Carburizing: Enhances surface hardness and wear resistance.
2. Tempering: Improves toughness while maintaining required hardness levels.
3. Annealing: Facilitates machinability and relieves internal stresses.
