201 cold rolled precision stainless steel coil has certain acid and alkali resistance, high density, no bubbles and pinholes when polished, and is a high-quality material for producing various watch cases, watch straps and bottom covers. 200 series stainless steel was first developed in the United States during World War II as a substitute for 300 series stainless steel. At that time, due to the war, nickel was strictly controlled as a strategic material, so austenitic stainless steel was developed to replace part or all of nickel with manganese (and nitrogen).
Although 201 has certain corrosion resistance, other types of stainless steel materials may need to be considered in highly corrosive environments. At the same time, regular cleaning and maintenance can extend the service life of 201 stainless steel and maintain its beauty and performance.
In China, the common 201 cold rolled precision stainless steel coil is the national standard, which is divided into 201 and J1, J2, J3, and J4. A variety of surface processing methods are available, such as frosted/brushed, 8K/mirror, etc.
