Dear Milad,

It depends on the waste and steel composition. You can try using some corrosion inhibitors if the waste is liquid, like molybdate, wolframate, benzotriazole, etc.

Dear Dr. Milad Vahman,

my answer is of a general nature because it would be necessary to know the corrosivity and the type of waste inside the container.

In this context, I would evaluate the use of a suitable coating system.

This approach needs some specific tests regarding the coating system (e.g. evaluation of its protection power against steel corrosion, adhesiveness measurements, “ease of decontamination” test, etc.), proofs of painting processing (preparation, layer thickness, etc.) and proofs of adequate painting condition at the latest possible point in time, i.e. after conditioning, just prior to storage.

Dear Milad

It highly depends on type of the steel. However, my recommendation to you is that you cannot use cladding or coating if the steel waste container is made of stainless steel. The latter is due to the formation of stable passive layer in stainless steel. In the contrast, if the steel waste container is made of low carbon steel (with low chromium content) galvanizing is recommended.

Milad, you can mitigate the environmental "corrosion" effect on the steel waste container by putting it in a highly alkaline solution (i.e., high pH). It can be a concrete solution [i.e, Ca(OH)2]. The solution with a high concentration of OH- lead to the passivity of the steel surface, especially for carbon steel. In addition, removing O2 via purge the solution with forming gas (i.e., a mixture of N2 and H2 gases) will lead to the reduction of water becomes the dominant cathodic reaction via the hydrogen evolution 2H2O + 2e = H2 + 2OH-.

It is to be noted here that, in field, there is a problem related to the corrosion influence of halides (i.e., Cl-, Br-, I-) on steel. The certain concentration of these halides can lead to the breakdown of the passive film that spontaneously forms on the steel surface.
