Material Disadvantage

201 Stainless Steel Round rods The disadvantage of this material is: 18% of chromium content and low nickel content is not up to the balance of the formation of ferrite, for this reason, 200 series of stainless steel chromium content to 15%~16%, in some cases to 13%~14%, its corrosion resistance is not comparable to 304 and other similar steel in addition, Under the common acidic conditions in the corrosive sites of sedimentary areas and cracks, manganese and some cases of copper reduce the effect of passivation. The 200-series steel is about 10-100 times faster than 304 stainless steel in these conditions. Also, in production is often unable to control the residual sulfur content and carbon content in these steels, materials can not be traced, even in the material recycling. If CR-MN steel is not indicated, they become a dangerous mixture of scrap steel, resulting in an unexpected high manganese content in castings.
