Based in the heart of Addis Ababa, Desta Steel stands as a trusted partner for industries requiring unwavering quality and reliability. We take pride in manufacturing and supplying premium Alloy Steel AISI 8620 Bars, a material chosen for its exceptional strength and versatility. Our commitment is to support Ethiopia’s growing industrial sector by providing a product that forms the robust backbone of critical machinery and components, ensuring our clients can build with confidence and drive their projects toward success.
This particular grade is a nickel-chromium-molybdenum alloy known for its excellent case hardening properties. In its annealed state, it offers good machinability and ductility. Once subjected to carburizing and heat treatment, the surface becomes extremely hard and wear-resistant, while the core remains tough and strong, capable of withstanding significant impact and fatigue stresses, making it a truly resilient material for demanding applications.

You’ll commonly find AISI 8620 bars at work in the most demanding parts of heavy machinery. It’s the ideal choice for gears, pinions, shafts, and other critical components that require a hard, durable surface to resist wear, coupled with a tough interior to absorb shock and stress. This makes it indispensable in sectors like automotive manufacturing for transmission parts, in mining equipment, and in large industrial gearboxes, where failure is not an option and performance is paramount.
