Molybdenum in Irons and Steels for Clean and Green Power Generation

Case studies

Car Body and Chassis Construction
Car Body and Chassis Construction
Car bodies and chassis are increasingly manufactured from high-strength steel (HSS). This study examines the use of HSS, particularly molybdenum-containing grades, to increase strength and reduce overall weight. Lighter vehicles manufactured with HSS use less fuel and emit less C02 while helping to increase passenger safety. HSS enables weight reductions of 20-25%, with ultra HSS having the potential to reduce weight by a further 20%.
Supercritical and Ultra-supercritical Power Plants
Supercritical and Ultra-supercritical Power Plants
Coal-fired power plants emit more CO2 per kWh than any other form of generation. This study looks at how molybdenum-containing steels and superalloys are used in modern coal-fired plants to increase high temperature strength and resistance to chlorine-containing flue gases.  These properties enable supercritical and new ultra-supercritical power plants to be run at higher temperatures, increasing thermal efficiency and delivering significant reductions in CO2 emissions.
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.

Molding plastics with molybdenum
09/08/2017
Molybdenum-alloyed mold steels are a key component of plastic injection-molding machines. They must be easy to machine into complex geometries that mirror the finished molding, resist deformation and wear under the stress and abrasion of the process, and be able to maintain a high surface polish for long production runs. Molybdenum is a vital alloying element in meeting these requirements.
Moly goes to the races
07/02/2017
A race car’s skeleton and many of the forged components, that keep its engine running at top speed, are made of chromoly steel. Even though these grades have been around for many decades, and numerous new materials have been developed since, they still are the materials of choice in critical applications. Molybdenum is therefore a vital component to a racing team reaching its ultimate goal – the winner’s circle.
Mobile cranes reach higher
21/09/2015
Today’s global demand to build infrastructure larger, faster and higher challenges crane manufacturers to keep pace by developing more powerful, versatile and cost-effective equipment. Molybdenum-containing high- and ultra-high-strength steels allow them to push performance boundaries to new heights.
Tool steels depend on molybdenum
26/08/2014
Many of the best tool steels require molybdenum to increase hardenability and toughness, and to form hard, wear-resistant carbides in the matrix. These attributes make molybdenum-containing tool steels the industry standard.
Molybdenum scrap saves resources
15/08/2013
A recent study found that about one quarter of the molybdenum used each year is recycled material from scrap sources. The rest is newly mined, primary molybdenum. Scrap therefore plays an important role in meeting demand and contributing to sustainability.
Shale energy revolution
15/08/2013
The world’s recoverable oil and natural gas reserves have increased dramatically in just a few years. Trapped deep underground in layers covering huge areas, shale reserves have only recently become accessible. The combination of two techniques, horizontal drilling and hydraulic fracturing, makes it possible to extract these precious natural resources economically. The United States, a pioneer in this area, has experienced a shale-gas revolution over the last five years. High-strength molybdenum steels are needed to drill the wells and extract the oil and gas.
Protecting vital plant equipment
15/08/2013
Molybdenum-bearing stainless steel enclosures for electrical, electro-mechanical and electronic equipment generally go unnoticed, but are very important. These enclosures are used in chemical plants and at other industrial sites with corrosive environments. They protect vital systems and instruments from chemicals, fumes, moisture and even fires or explosions.

High-strength steel – sustainable and money saving
12/02/2013
Molybdenum’s unique properties are often used to deliver sustainability advantages in energy production, energy efficiency, resource conservation and environmental protection. The newly-constructed Friends Arena in Solna Municipality, Stockholm, is a great example of how “a little moly goes a long way” in reducing the environmental impact of a new building and saving cost at the same time.
