ASME SA 387 Grade 91 Class 1 & 2 Sheets and Plates are chromium-molybdenum steel plates utilized for high-temperature and pressure services. These plates contain 9% Chromium and 1% Molybdenum, which offer higher strength, oxidation resistance, and improved toughness at elevated temperatures. These plates are most suitable for applications that require higher thermal stability and corrosion resistance, and thus are most suitable for demanding industrial applications.
