Welcome to ‘Stainless Solutions’ from IMOA. Each month, we will cover a different stainless steel issue with tips on design and specification, and links to technical resources. This month we are introducing new resources on the sustainability of molybdenum containing stainless and carbon steels.
Sustainable Resources


The decisions made in a wide range of industries have a direct effect on the sustainability of our buildings and cities. For example, pollutant emissions can be reduced by choosing longer life construction materials, alternative energy sources, and scrubber systems to minimize emissions.  Higher strength carbon and corrosion-resistant stainless steels minimize resource use. Water is a valuable resource and its handling, treatment and recycling are increasingly important sustainability factors.

 


IMOA’s website has several resources that may be helpful including our Sustainable Architecture page which has links to articles, case studies and life cycle assessment studies. IMOA’s website also has information about molybdenum’s life cycle inventory (LCI) as well as other sustainability information.  The International Stainless Steel Forum’s Sustainability website is also an excellent resource.

IMOA has published several case studies and Life Cycle Assessments related to the contribution molybdenum makes to sustainable development:

Architecture, Building & Construction

Friends Arena, Stockholm


Molybdenum is an important alloying element in high-strength steel (HSS), which enables lighter and stronger structures than conventional steel. This study looks at the use of HSS in the Friends Arena, Stockholm, which reduced the quantity of steel used for construction by 17% and also cut greenhouse gas emissions by 17% over the lifetime of the stadium.

Federal Building, San Francisco

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.

Benefits of molybdenum use: The Myllysilta Bridge, Finland

Duplex stainless steel provides exceptional resistance to pitting and crevice corrosion from chlorides, and is therefore ideally suited to areas exposed to coastal waters and deicing salts.

What is IMOA?

IMOA (International Molybdenum Association) is a non-profit industry association, which provides technical information to assist with successful specification of molybdenum-containing materials. Molybdenum is an element. When it is added to stainless steel, molybdenum increases its resistance to corrosion caused by deicing salts, coastal atmosphere and pollution.

If you have a topic suggestion for a future issue of Stainless Solutions or need additional technical advice on stainless steel specification and selection, please get in touch here.
