201 stainless steel is a kind of certain acid, alkali resistance, high density, polishing no bubbles, no pinholes and other characteristics, is the production of the case, strap bottom quality materials. Mainly used as decoration pipe, industrial pipe, some of the light stretching of the products. In: C) carbon, (Si) silicon, (Mn), (Cr) chromium, (N) N, (P) P, (S) sulfur, (Ni) Nickel%, (Cu) Copper: Copper semi / high Copper is the main chemical ingredient. 200 series stainless steel applications so successful in India, due to likely alternative to 304 stainless steel in certain applications. Most of the 200 series stainless steel sold in the Chinese market is almost no control in accordance with the national standard sulfur, carbon content, manganese (and nitrogen) to replace some or all of the nickel to produce a lower nickel content of austenitic stainless steel. In our country there are the following 200-series grades: J1, J3, J4,201,202. 200, etc., and later appeared on the nickel content steel lower control, as to 201C, that is, the idea that the late Chinese steel mills developed 201 individual National Standard Grade 201 is: 1Cr17Mn6Ni5N, 201C on the basis of 201 continue to reduce the nickel content, increasing the content of manganese.
