25 Cr duplex (austenitic/ferritic) stainless steel containing copper and nitrogen offers a cost effective solution to material selection for pollution control equipment. The properties of duplex stainless steel which make it suitable for this type of application are discussed and long term performance histories presented. It is concluded that high alloy duplex steel has an important role to play in the production of low maintenance reliable equipment for FGD and other pollution control systems.
