Water is essential to life but global supplies are under pressure from population growth and may be unable to sustain total demand by 2025. Desalination plants provide reliable, sustainable supplies of fresh water but need to be constructed from materials that can withstand such hostile environments. This case study explores the sustainability benefits of using molybdenum-containing stainless steel in the construction of seawater desalination plants, greatly increasing resistance to corrosion and enabling cost-effective, reliable operation.

Sunscreens greatly reduce the need for air conditioning in buildings. The Federal Building in San Francisco was built with computer-controlled stainless steel sunscreens which, together with natural ventilation, reduce the energy needed to cool the building by two-thirds. The molybdenum-containing stainless steel is highly corrosion resistant and is specified for a design life of 100 years.

Molybdenum brings safety into swimming pool buildings. This case study has been kindly contributed by Dr Peter Dierschke, Materials Consultant to the Hempel Special Metals Group, Oberhausen, Germany

Stainless steel with 6% Mo improves equipment efficiency and eliminates costly repair. This case study has been provided by Thomas Stoner of Hercules Incorporated and Kelly Wyrough of Roben Manufacturing and was written by IMOA consultant John Grocki.

A rendering plant has been using a Type 304L stainless steel (SS) heat exchanger to condense the rendering cooker gases and heat plant water. This case study has been provided by Dave Bennett of M&M Engineering and has been written up by IMOA consultant John Grocki of Advantage Resources Consulting.

Molybdenum keeps street handrails safe and attractive. This article has been written by an IMOA consultant, Catherine Houska of TMR Stainless, who will play a leading part in IMOA’s effort to promote molybdenum containing stainless steels in the area of outdoor applications in architecture, building and construction.

A large, international, food manufacturing company encountered through-wall leaks in a Type 304 stainless steel hot water line after only two years of service. Nicole Kinsman, formerly of Technical Marketing Resources, consultants to IMOA, is the author.

Many aging US power plants have copper alloy condensers that are suffering from erosion or corrosion. Many power plants have solved the problem permanently by replacing the tube bundles with 4 to 6% molybdenum- containing stainless steels. Edward Blessman of Trent Tube, East Troy, Wisconsin, contributed the information in this article and IMOA would like to thank him for his assistance. Nicole Kinsman, formerly of Technical Marketing Resources (Consultants to IMOA) is the author.

A North American nuclear power plant originally had a lined carbon steel service water piping system. The system began to deteriorate within a few years of installation, especially at the welded joints of the carbon steel piping.
