The chromium content of the 200 series stainless steel is reduced to 13.5% ~ 15%, and in some cases to 13% ~ 14%. Its corrosion resistance is not comparable to that of 304 and other similar steels. In addition, manganese and in some cases copper reduce the effect of re-passivation under acidic conditions common in the corroded sites of sedimentary zones and crevices. The destruction rate of 200 series steel under these conditions is about 10-100 times that of 304 stainless steel. The residual sulfur and carbon content of these steels is often not controlled during production, and the materials cannot be traced back to their source, even in the case of material recycling. If Cr-Mn steels are not accounted for, they can become a dangerous scrap mix, resulting in an unexpectedly high manganese content in castings.
