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.
