200 series stainless steel used in India is so successful is because certain uses may substitute 304 stainless steel. Sold in the Chinese market, the majority of 200 series stainless steel according to GB almost no control of the content of sulfur, carbon, and to replace some or all of the nickel-manganese (and nitrogen) to produce a lower nickel content in austenitic stainless steel. The disadvantage of this series of materials is: 18% of the chromium content and a low nickel content reach balanced formation of ferrite, for 200 series stainless steel, the chromium content is reduced below 15% to 16%, in some cases fell to 13% to 14%, its corrosion resistance can not be compared with the 304 and other similar steel Moreover, in the common parts of the deposition zone and crevice corrosion under acidic conditions, manganese and copper in some cases reduce the re blunt of the role. 200 series steel destruction rate under these conditions is about 10-100 times in 304 stainless steel. Also, it is often in the production can not be controlled to these steels residual sulfur content and carbon content, the material is not traceable to track, so even in the recycling of materials. Description Cr-Mn steel, they will become a dangerous scrap mixed raw materials, castings contain unexpected high manganese content
