201 stainless steel material has the characteristics of being polished without bubbles or pinholes, making it a high-quality material for producing various watch cases, strap covers, etc. Mainly used for decorative pipes, industrial pipes, and some shallow stretched products. 201 stainless steel plate has the ability to resist general corrosion similar to unstable nicke chromium alloy 304. Long term heating of 201 stainless steel plate in the temperature range of chromium carbide degree may affect the performance of alloy 321 stainless steel plate and 347 in harsh corrosive media. 201 stainless steel plate is mainly used for high-temperature applications, which require the material to have strong resistance to sensitization to prevent intergranular corrosion at lower temperatures.
