Effect of humidity and temperature on corrosion of RMRS grade B marine steel plate

Effect of humidity on corrosion of RMRS grade B marine steel plate:
The RMRS grade B marine steel plate surface is exposed to air continuously or intermittently in the marine atmosphere area, marine splash area and sea water tidal range area erosion will be affected by atmospheric humidity. The surface of RMRS grade B marine steel plate is covered with a layer of corrosive water film, which strengthens its corrosion. The surface of RMRS grade B marine steel plate can not only contact with the corrosive salt solution provided by the water film, but also directly contact with the oxygen in the atmosphere, which conforms to the electrochemical corrosion law in the electrolyte. Generally speaking, the higher the humidity in the marine environment, the more serious the corrosion of RMRS grade B marine steel plate.

Effect of temperature on corrosion of RMRS grade B marine steel plate:
For any chemical reaction, temperature is an important factor. Temperature not only directly affects the corrosion of RMRS grade B marine steel plate in the marine environment, but also indirectly affects the corrosion through other factors. In general chemical reactions, the reaction rate will increase to twice for every 10 °C increase in temperature. The corrosion rate varies with the temperature in different sea areas and seasons. The temperature also changes with the change of altitude and sea water depth. When the sea water reaches a certain depth, the temperature change is not obvious, and it is not the main factor affecting corrosion of RMRS grade B marine steel plate any more.
