Series 200 austenitic stainless steel is developed on the basis of chromium and nickel. In addition to manganese and nitrogen, the austenitic elements generally contain an appropriate amount of nickel. This series of stainless steel is suitable for the use of equipment and components with low requirements for heavy load and corrosion resistance.
201 stainless steel plate has the characteristics of polishing, no bubbles, no pinholes and so on. It is a high-quality material for the production of various watchcases and watchband covers.
Surface treatment
The purpose of the surface treatment
In daily life, surface treatment technology is usually used to change the surface properties of solid materials, so as to improve appearance, improve corrosion resistance, wear resistance, reduce friction, improve hardness, and improve surface fatigue strength and heat resistance.
2B is a kind of surface treatments. After 2B treatment, it is subject to a light cold rolling through the polishing roller to obtain appropriate gloss. This is a common surface machining, which can also be used as a polishing tool.
