Key Features and Benefits

Alloy Composition: AISI 8620 is a low-alloy steel containing nickel, chromium, and molybdenum, which enhances its core strength, toughness, and wear resistance.
Case Hardening Capability: This steel is known for its excellent case hardening characteristics, which provide a hard exterior layer while maintaining a tough, ductile core.
Good Machinability: Before case hardening, AISI 8620 exhibits good machinability, allowing for easier shaping and forming of components.
High Core Strength and Toughness: The alloying elements ensure that the core retains high strength and toughness after heat treatment, essential for withstanding high stress and impact.
Weldability: Offers good weldability with preheating and proper heat treatment post-welding, expanding its versatility in applications.
Durability: The combination of a hard surface and a tough core results in parts that are highly durable and capable of withstanding harsh operational environments.
Enhanced Wear Resistance: The hard outer surface significantly enhances wear resistance, making it ideal for parts that must endure heavy and repeated use.
Cost-Effective Manufacturing: The good machinability of AISI 8620 reduces manufacturing time and tool wear, making the production process more cost-effective.
Reliability in Performance: AISI 8620’s properties ensure reliable performance under various loading conditions, contributing to the overall safety and efficiency of the machinery.
