In the heart of Addis Ababa’s industrial landscape, Desta Steel stands as a trusted partner for projects demanding uncompromising strength and reliability. We specialize in providing superior SA 515 Grade 70 steel sheets and plates, materials engineered to perform under the most demanding conditions. Our commitment is to support Ethiopia’s growth by supplying the essential building blocks for critical infrastructure and heavy-duty fabrication, ensuring every piece meets the highest standards of quality and safety for your most important ventures.
The composition of SA 515 Grade 70 is carefully balanced, primarily a carbon steel fortified with manganese, silicon, and other elements to achieve its renowned toughness. This specific chemistry grants it exceptional mechanical properties, most notably a minimum yield strength of 38,000 psi (260 MPa), which allows it to withstand immense pressure without deforming. Its excellent notch toughness is particularly valuable, meaning it can absorb significant impact energy, especially in lower temperature environments, preventing brittle fracture.

This exceptional combination of strength and resilience makes SA 515 Grade 70 the material of choice for critical pressure vessels and boilers, where it safely contains high-pressure steam and gases. Its applications extend to heavy-duty storage tanks for the petrochemical industry, large-diameter pipes for energy transmission, and structural components in major construction projects like bridges and industrial facilities. Essentially, it is specified wherever structural integrity under stress and temperature variation is an absolute necessity for long-term safety and performance.
