Located in the heart of Addis Ababa, Desta Steel is a trusted name for reliable industrial components, built on a foundation of quality and a deep understanding of local needs. We take pride in manufacturing and supplying a range of essential products, including the robust Alloy Steel Gr B5 Washer, which is engineered to meet the rigorous demands of Ethiopia’s growing industrial and construction sectors, ensuring strength and durability where it matters most.
The Alloy Steel Gr B5 Washer is defined by its specific metallurgical composition, primarily a chromium-molybdenum blend that gives it a distinct advantage. This alloying creates a material that is not only exceptionally strong but also highly resistant to wear and deformation under stress. Its mechanical properties include a high tensile strength and a hardened surface, allowing it to maintain integrity and provide a secure, lasting bearing surface even in the most demanding high-pressure applications.
