Sayed Steel, a trusted manufacturer and supplier based in Safat, Kuwait, proudly offers high-performance ASME SA 387 Grade 91 Class 1 & 2 sheets and plates. We understand the critical demands of modern industrial applications, which is why we provide this advanced chromium-molybdenum alloy steel known for its exceptional strength and reliability. Our commitment lies in delivering materials that meet the most rigorous international standards, ensuring your projects in power generation and heavy fabrication are built on a foundation of quality and durability, supported by our local expertise and global supply chain capabilities.
This grade is a chromium-molybdenum alloy steel strengthened by vanadium and niobium, creating a material with superior high-temperature capabilities. Its key mechanical properties include excellent tensile strength and outstanding creep resistance, allowing it to perform reliably under sustained stress and extreme heat. This combination makes it far more robust than standard carbon steels, capable of handling demanding environments where pressure and temperature are significant factors, ensuring long-term structural integrity.
