AISI 8620
It is designed to achieve a hard, wear-resistant surface while maintaining a tough and ductile core, making it ideal for components subjected to high surface stresses and impact loads. Commonly used in automotive, aerospace, and heavy machinery industries, AISI 8620 forgings offer a balance of machinability, heat treatability, and cost-effectiveness.
Descriptions
1. Chemical Composition
AISI 8620 contains nickel, chromium, and molybdenum to enhance hardenability, core toughness, and wear resistance. Its low carbon content makes it suitable for carburizing or nitriding processes.
2. Mechanical Properties
AISI 8620 forgings are typically carburized or heat-treated to enhance surface hardness. Properties vary based on processing methods and case depth.
3. Key Advantages
Superior Case Hardening: Achieves high surface hardness (HRC 58–63) with excellent core ductility.
Good Machinability: Easily machined in the annealed or normalized condition.
Cost-Effective: Balances performance and affordability for mass production.
Fatigue Resistance: Ideal for cyclic loading due to tough core and hard surface.
