Ordinary steel plate or stainless steel, which one is better for for marine steel plate?

Is it better to choose ordinary steel plate for marine steel plate? Or is stainless steel better?

The working environment of the ship is extremely harsh. The hull shell has to withstand the corrosion of seawater, marine organisms and microorganisms; the hull also has to withstand large wind and wave shocks and alternating loads; the shape of the ship makes its processing technology more complex. Complex, so the requirements for steel for hull structure are more stringent.

First of all, good toughness is the most critical focus of marine steel plates. In addition, marine steel plates require high strength, good corrosion resistance, excellent weldability, formability and surface quality.

Of course, in order to ensure quality and sufficient toughness, marine steel plates require that the content of chromium and manganese should be above 2.5%, and there are also strict requirements on the content ratio of carbon metal elements, and they should be produced by steel mills approved by the ship inspection department.

Having said so much, is it better to choose ordinary steel plates for marine steel plates? Or is stainless steel better?

In fact... it is necessary to choose stainless steel plate or ordinary steel plate according to the different needs of the ship.
