Operating from the heart of Addis Ababa, Desta Steel is your trusted local partner for high-performance fastening solutions. We proudly manufacture and supply Alloy Steel Grade 10.9 bolts, engineered to meet the most demanding standards. Recognized for their exceptional strength and reliability, these bolts are a cornerstone for projects where safety and durability are non-negotiable. We ensure consistent quality and timely delivery, supporting Ethiopia’s growing infrastructure and industrial sectors with components built to last and perform under significant pressure.
The exceptional strength of Grade 10.9 bolts comes from a specific alloy steel composition, typically including elements like chromium and molybdenum, which is then heat-treated through quenching and tempering. This process results in a tensile strength of 1040 MPa minimum and a yield strength of 940 MPa, meaning they can withstand immense loads without permanently deforming. This high strength-to-weight ratio, combined with good resistance to shock and vibration, makes them a superior choice for critical, heavy-duty applications where failure is not an option.
