　　A299 steel plate Application:

　　A299 steel plate is commonly used throughout the oil industry (including inshore and offshore), the petrochemical industry and the gas production industry. A299 has good strength, it can be made of boilers and components to withstand a certain long-term high temperature stress; Boiler steel plate has good toughness and low effectiveness of the tendency in the use of bending, curling, deformation processing such as cold, after more prolonged storage and use remains a good toughness; A299 also has good weldability and resistance to intergranular corrosion. For the manufacture of boiler drum, beams and wall panels.
