201 stainless steel has certain acid and alkali resistance, high density, polished without bubbles, pinholes, etc. It produces various high-quality materials for watch cases, strap and bottom cover. It is mainly used for decorative pipes, industrial pipes, and some shallow stretched products.

The chromium content in 200 series stainless steel has dropped to 13.5% to 15%, and in some cases it has dropped to 13% to 14%. Its corrosion resistance cannot be compared with 304 and other similar steels. In addition, under common acidic conditions in the corrosive areas of the deposition zone and the gap, manganese and copper in some cases reduce the repassivation effect. The 200 series steel destroys approximately 10-100 times faster than that of 304 stainless steel in these conditions. In production, the residual sulfur content and carbon content in these steels are often not controlled, and the materials cannot be traced, even in material recycling. If Cr-Mn steels are not stated, they become a dangerous scrap steel mixture raw material, resulting in unexpected high manganese content.
