Operating from the heart of Addis Ababa, Desta Steel is a trusted partner for Ethiopia’s heavy industry, providing critical materials for projects where safety and durability are non-negotiable. We take pride in supplying high-integrity ASME SA 387 Grade 11 Class 1 & 2 plates, a product line designed to withstand the most demanding high-temperature and high-pressure environments, ensuring our clients build with confidence and longevity in mind.
This specific chromium-molybdenum alloy steel is defined by its excellent composition, primarily chromium and molybdenum, which grants it superior strength and resistance to oxidation and corrosion, especially under elevated temperatures. The mechanical properties are rigorously controlled to ensure high tensile strength and excellent notch toughness, allowing these plates to perform reliably in critical service conditions where ordinary steels would fail.
