201 stainless steel, with acid, alkali, high density, polishing no bubbles, no pinholes, etc., is the production of case, strap bottom high-quality materials. Mainly used for decoration pipes, industrial pipes, some of the shallow stretch of the products.

There are several major Chinese steel 200 system: J1, J3, J4, 201,202. Later appeared on the control of lower nickel content steels such as 200, as you ask the 201C, which is developed by the late Chinese steel mills 201 individual extended steel, grade 201 national standards are: 1Cr17Mn6Ni5N, 201C in 201 continue on the basis of reduced nickel content, increasing manganese content.
