Strategically located in the heart of Addis Ababa, Desta Steel stands as a trusted partner for industries across Ethiopia, providing reliable access to essential materials like SA 516 grade 65 sheets and plates. We understand that the backbone of major infrastructure and energy projects depends on the integrity of the raw materials used. That’s why we are committed to supplying this specific pressure vessel quality steel, ensuring our clients receive a product that meets rigorous standards for safety and performance, supporting the nation’s growth with unwavering quality and dependable service.
The composition of SA 516 grade 65 is carefully balanced, primarily consisting of carbon and manganese, which gives it excellent strength and notch toughness, especially in moderate to lower temperature environments. This careful formulation results in impressive mechanical properties, including a high tensile strength and a specified minimum yield point that makes it exceptionally resistant to deformation under immense pressure. It’s this reliable combination of ductility and strength that makes it a preferred choice for critical containment applications where failure is not an option.
