2304 corrosion resistance and use environment :
2304 is a ferrite - austenitic duplex stainless steel, with the common characteristics of duplex stainless steel.2304 duplex stainless steel intergranular corrosion resistant performance is good, has good corrosion resistance in nitric acid, can be comparable to 304 L, in other acid, such as sulfuric acid, with 316 L, its corrosion resistance in organic acids such as formic acid, even better than 316 L.
It can be used in the manufacture of amine recovery equipment, fermentation equipment for hydrocarbons, etc. In addition, it can also be used as heat exchanger for the manufacturing industry, cooking pot preheater for the pulp and paper industry, and train seat frame for wet and hot, offshore areas, etc.
