Stainless Steel 201
Stainless Steel 201
Stainless steel 201 offers a certain degree of resistance to acids and alkalis, with high density and a polished surface free of bubbles or pinholes. It is a premium material for manufacturing various watch cases and back covers for watch straps, and is mainly used in decorative pipes, industrial pipes, and some shallow-drawn products.
