A387 Carbon Steel Plate
ASTM A387 is a chromium-molybdenum alloy steel plate engineered for high-temperature pressure vessel and boiler service, available in Gr 11, Gr 22, Gr 91 and other grades for diverse high-temperature working conditions. It boasts exceptional high-temperature strength, creep resistance and impact toughness, maintaining stable structural performance under long-term high-heat and pressure-bearing environments. With good weldability via standard pre-treatment, it features customizable thickness, width and length with precise dimensional tolerance, serving as a core specialized material for high-temperature pressure-bearing industrial equipment fabrication.
