Operating from the heart of Addis Ababa, Desta Steel stands as a trusted hub for industrial quality, bringing specialized materials directly to Ethiopia’s growing infrastructure. We are particularly proud to supply ASME SA 387 Grade 91 Class 1 & 2 sheets and plates, a critical high-performance steel for demanding projects. By offering this premium-grade material locally, we empower our nation’s engineers and fabricators with reliable access, supporting the construction of stronger, more efficient industrial systems right here at home. Our commitment is to provide not just steel, but robust solutions that drive progress.
The strength of this material lies in its sophisticated balance. ASME SA 387 Gr 91 is a chrome-molybdenum alloy steel enhanced with vanadium and niobium, creating a fine-grained microstructure. This unique composition gives it excellent mechanical properties, including high tensile and yield strength, along with superior resistance to creep—the tendency to deform under sustained heat and stress. It maintains this formidable durability even at elevated temperatures up to 600°C, making it a go-to choice where standard steels would falter under thermal pressure.
