Operating from our base in Manama, Bahrain, Ahmer Steel has built a strong reputation as a dependable manufacturer and supplier of high-performance steel products. We take particular pride in our expertise with ASME SA 387 Grade 91 Class 1 & 2 sheets and plates, materials designed to meet the toughest industrial demands. Our commitment is to provide clients across the region with superior quality and reliable service, ensuring they receive the robust materials needed for their most critical projects, backed by our deep understanding of the specifications and applications.
At the heart of this material’s reliability is its specific chemical composition, which includes chromium, molybdenum, and vanadium. This alloying creates a fine-grained steel with exceptional mechanical properties, including remarkable strength and excellent resistance to creep—the tendency to deform under high temperatures and constant stress over time. These inherent characteristics are what make Grade 91 Class 1 & 2 plates a trusted choice for environments where both structural integrity and high-temperature performance are non-negotiable requirements.
