A387gr11 high strength boiler vessel steel sheet

A387Gr11 high-strength boiler vessel steel plate is a special steel with good heat resistance and corrosion resistance. The size standard of A387gr11 boiler and pressure vessel steel plate is: the thickness is 3mm-200mm, the width is 1000mm-3500mm, and the length is 3000mm-18000mm. A387Gr11 boiler steel is used in the manufacture of various boiler vessels such as boiler walls, chimneys, chimneys and other equipment components. A387Gr11 steel is a low-alloy, high-strength, heat-resistant, and corrosion-resistant steel that is ideal for boiler vessels.

A387Gr11 Boiler and Pressure Vessel Steel Plate is a low alloy steel whose main components are carbon, manganese, molybdenum, chromium and aluminum. Its carbon content is low, generally between 0.07% and 0.13%, silicon content is extremely low, generally below 0.15%, sulfur content is extremely low, generally below 0.03%, and aluminum content is generally between 0.02% and 0.06%. between. The size of A387gr11 high-strength boiler vessel steel plate has a certain range, and A387Gr11 steel is required to choose the appropriate size according to different applications to ensure safe and reliable use.
