Some knowledge about 201 stainless steel plate

201 stainless steel has the characteristics of polishing, no bubbles, no pinholes, etc. It is a high-quality material for the production of various watch cases, strap bottom covers, etc.

Mainly used for decorative pipes, industrial pipes, and some shallow-drawn products. 201 stainless steel plate has the ability to resist general corrosion similar to the unstable nickel-chromium alloy 304. Prolonged heating of 201 stainless steel in the temperature range of chromium carbide levels may affect alloy 321 and 347 in harsh corrosive media. 201 stainless steel plate is mainly used in high temperature applications, which require the material to have strong sensitization resistance to prevent intergranular corrosion at lower temperatures.
