Steel Plate Used for Oil Pipe
This type of steel plate is commonly used to the deep sea oil field. It is of high quality, and has the excellent performance like high tension, extremely low-temperature toughness, good weldability, as well as damage resistance. The steel plate is in full compliance with the standards, including API: 5CT-H40, J55, K55, and N80.
