• 4340 low carbon steel

  • The cleanliness of the 4340 low carbon steel has a great influence on the safety of the tank and the quality of the oil stored. Keeping the 4340 low carbon steel clean can slow down the corrosion of the tank wall and reduce the pollution to the oil. If the inside of the 4340 low carbon steel is not cleaned all the year round, a lot of rust and metal impurities will be produced in the tank. These impurities will cause the oil to slowly oxidize and deteriorate. The impurities mixed into the oil will also block the filter and oil circuit, causing oil supply failure.
