Description

This presentation discusses the research effort that led to the development of Type 204 Cu stainless. To achieve lower cost than Type 304, nickel content was nominally reduced from 8.5 to 2.5 percent. To achieve a similar corrosion resistance, tensile strength and work hardening rate as Type 304, several key elemental modifications were necessary. Data are presented comparing the strength, work hardening rate, formability and corrosion resistance of the two alloys. Potential uses for Type 204 Cu and current field experience are discussed.
