8620 Low Alloy

8620-low-alloy-product-image

Strong, tough, and reliable, 8620 alloy steel is widely used for carburized components requiring a durable surface and tough core. AISI 8620 steel offers balanced strength, medium hardenability, and shock resistance, making it suitable for demanding engineering and automotive applications.

Key Features

AISI 8620 steel is a nickel chromium-molybdenum 8620 steel alloy specifically developed for carburizing applications. It delivers a hard, wear-resistant surface while maintaining a tough and ductile core. Through controlled heat treatment, the properties of SAE 8620 steel can be precisely adjusted to meet specific case depth and core strength requirements, ensuring consistent performance in critical components.

Typical Applications
  • Differential ring gears
  • Camshafts and piston pins
  • Transmission gears
  • Steering worm gears
  • Spline shafts and high strength fasteners
  • Carburized chains and chain pins
  • Components requiring medium strength tough core with wear resistant surfaces
Forms of Supply

Supplied as round bars in annealed condition, with diameters ranging from 20 mm to 350 mm. As experienced steel manufacturers in UAE, we provide custom cut lengths for single or bulk orders to meet project specific requirements.

8620 alloy steel is a popular low alloy steel. It offers a strong balance of strength, toughness, and wear resistance after carburizing. AISI 8620 steel works well for components needing a hard surface and a durable, shock-resistant core.

 

As reliable steel manufacturers in UAE specializing in ferrous metals, we supply 8620 steel alloy across the region. We serve clients in Oman and Saudi Arabia. The controlled chemistry of 8620 material ensures consistent performance in precision-engineered and load-bearing applications.

Key Advantages of 8620 Steel
    • Designed for carburized and case-hardened components
    • Provides a tough core with excellent surface wear resistance
    • Good machinability in the annealed condition
    • Suitable for automotive, industrial, and mechanical parts
    • Consistent quality meeting SAE 8620 steel and AISI 8620 standards

Technical Specifications
