Excerpted from the second edition of the “Control Valve Handbook”, edited by J.W. Hutchison, ISA. This table serves as a general guide for selecting appropriate materials when they come into contact with certain fluids. The recommendations in the table are not absolute, as the corrosion resistance of materials depends on factors such as the concentration, temperature, pressure, and impurities of the fluid. Therefore, it must be emphasized that this table can only serve as a guideline.
