Welcome to Desta Steel, your trusted partner in Addis Ababa for high-strength industrial components. We take pride in manufacturing and supplying the robust Alloy Steel Grade 10.9 Washer, a critical element engineered for the most demanding applications. Our commitment to quality ensures that every washer meets rigorous standards, providing our clients across Ethiopia with the reliability and durability needed to build stronger, safer, and more resilient structures and machinery, supporting the nation’s growing infrastructure and industrial ambitions.
The composition of this washer is a careful blend of alloys, including carbon, manganese, and chromium, which work in concert to create its exceptional strength. This specific formulation is heat-treated to achieve the Grade 10.9 classification, resulting in a washer with a formidable tensile strength and a high yield point. It is designed not to deform under immense pressure, maintaining a secure clamp force to ensure the integrity of the bolted joint it supports.
