304l stainless steel plates have good corrosion resistance and can work in harsh environments. And it can be applied to a wide range of industries, such as light industry, heavy industry, shipping and aerospace industry. However, some manufacturers have found that their stainless steel pipes are prone to developing white rust. So, how exactly can this be prevented? Surface treatment can reduce the occurrence of white rust on the coating. Stainless steel plates should be covered and stored in a dry and well-ventilated environment. If the steel pipes can only be stored outdoors, the objects should be lifted off the ground and separated with narrow gaskets to provide all the steel pipes with freely flowing air. Coated steel pipes should not be placed in areas that may be affected by rain, fog, condensation and snow. Another important point is that during shipping, 304l stainless steel plates should be placed in the middle and upper decks. Because it is placed on the lower layer and is prone to contact with seawater. The seawater at the bottom of the ship is prone to form sewage, thereby causing certain corrosion. Therefore, for 304l stainless steel plates, sea transportation should be reduced or land transportation should be adopted more.
