When choosing dual-phase stainless steel in different corrosive environments, it should be noted that the corrosion resistance of steel is always relative, although dual-phase Stainless steel has good local corrosion resistance, for a dual-phase stainless steel, it also has an applicable medium condition

Include temperature, pressure, medium concentration, pH value, etc., need to be carefully selected.In order to meet the requirements of the actual engineering conditions.If necessary, it is necessary to carry out corrosion test in the real medium or the hanging piece test under the field condition, or even the test of the simulation device.
