Description

The general is according to austenite and ferrite, two-way stainless steel and markov stainless steel, mainly divided into two series, 3 series, 4, 5 and 6 is system of the department of stainless steel. **6 and **7 stainless steel (**7 stainless steel performance see) is molybdenum of stainless steel. **7 stainless steel in the molybdenum content by slightly in **6 stainless steel. Because of molybdenum in steel, this type of steel overall performance than the **0 and **4 stainless steel, high temperature conditions, when sulfuric acid concentration less than *5% or more than *5%, **6 stainless steel for a wide range of applications. **6 stainless steel has good resistance to chloride erosion performance, so usually used in the Marine environment. **6 l stainless steel the biggest carbon content 0.*3, can be used for welding can not carry out after annealing and maximum corrosion resistance in the use of Corrosion resistance The corrosion resistance of **6 is better than that of **4 stainless steel, in pulp and paper production process has good corrosion resistance performance. And **6 stainless steel also resistance to sea and aggressive industrial atmosphere of erosion. Heat resistance In ***0 degrees below intermittent use and in ***0 degrees the following continuous make
