What are the causes of 304 material rusting

2019-12-12 By zhaozhao

1. There are chloride ions in the use environment. Chloride ions exist widely, such as salt, sweat, seawater, sea breeze, soil and so on. In the presence of chloride ions, the corrosion of stainless steel is very fast, even more than ordinary low carbon steel. Therefore, the use of stainless steel environment requirements, and often need to wipe, remove dust, keep clean and dry.
2. No solution treatment. The alloy elements did not dissolve into the matrix, resulting in low alloy content in the matrix structure and poor corrosion resistance.
3. This material without titanium and niobium has a natural tendency of intergranular corrosion. The intergranular corrosion can be reduced by adding titanium and niobium together with stable treatment.
In order to make stainless steel not only have good corrosion resistance but also have good mechanical and physical properties, according to different requirements, in addition to the high content of alloy element chromium, other alloy elements such as nickel, molybdenum, manganese, nitrogen are added to the steel. In this way, not only can the chemical composition of the passivation film be changed and its corrosion resistance in harsh medium be strengthened, but also the steel can obtain enough strength, plasticity, and toughness, as well as good process performance, such as weldability, processability, etc.
