Analysis of the reasons for the rust of stainless steel strips

1. Chloride ions exist in the use environment. Chloride ions are widely present, such as salt, sweat, seawater, sea breeze, soil and so on. In the presence of chloride ions, stainless steel strips corrode rapidly, even more than ordinary mild steel. Therefore, there are requirements for the use environment of the stainless steel strips, and it needs to be wiped frequently to remove dust and keep it clean and dry.
2. Not solution treated. The alloying elements are not dissolved into the matrix, resulting in low alloy content in the matrix structure and poor corrosion resistance, resulting in rust of the stainless steel strips.

3. This titanium- and niobium-free material has an inherent tendency to intergranular corrosion. The addition of titanium and niobium, together with stabilization treatment, can reduce intergranular corrosion.
