Operating from Muscat, Oman, Faisal Steel has built a strong reputation as a trusted manufacturer and supplier of high-performance steel products. Our expertise is exemplified by our supply of ASME SA 387 Grade 91 Class 1 & 2 sheets and plates, materials engineered for the most demanding industrial environments. We pride ourselves on delivering not just metal, but reliability and durability to projects across the region, ensuring our clients receive material solutions that meet the highest international standards for quality and performance.
The strength of Grade 91 lies in its carefully balanced composition, primarily chromium and molybdenum, enhanced with vanadium, niobium, and nitrogen. This specific alloying creates a material with exceptional mechanical properties, including remarkable tensile strength and outstanding resistance to creep. These characteristics allow it to maintain its structural integrity under extreme temperatures and high-pressure conditions, making it a fundamentally robust choice where ordinary steels would fail, providing long-term safety and efficiency.
