Located in the heart of Addis Ababa, Desta Steel is your trusted local partner for industrial strength and reliability. We take pride in manufacturing and supplying high-integrity fastening solutions, with our Alloy Steel Grade B16 Fasteners standing as a testament to our commitment to quality. Engineered to meet the rigorous demands of Ethiopia’s growing industrial sectors, these components are built to ensure safety and durability in even the most challenging applications, providing a foundation of trust for projects that depend on unwavering performance.
The strength of these fasteners comes from a specific composition that includes chromium and molybdenum, giving them exceptional mechanical properties. They are heat-treated to achieve a high tensile strength and impressive yield point, allowing them to withstand significant pressure and stress without deforming. This combination ensures excellent resistance to creep and fatigue, making them reliably tough under sustained loads and elevated temperatures, which is crucial for long-term structural integrity.

Due to their robust nature, these fasteners are indispensable in high-pressure environments. You will find them securely fastening critical components in power generation plants, especially in steam pipelines and turbine assemblies. They are also essential in the construction of heavy industrial machinery and pressure vessel systems, where failure is not an option. Their ability to perform under heat and stress makes them a preferred choice for engineers who prioritize safety and longevity in their designs.
