Heather Allain, Executive Director, Materials Technology Institute (MTI), tells us about her passion for materials and the importance of MTI’s work to provide awareness of safe, reliable and sustainable materials use.
Nickel can be found in many forms from nanowires to stainless steel alloys. But what are the properties of nickel that make it an essential element in batteries?
Nickel-based catalysts are key to supplying energy to power our transportation of goods and people, whether by land, sea, or air.
According to the International Energy Agency, renewable fuel demand is expected to grow rapidly over the next few years. Steve Deutsch from The Catalyst Group explains the role of nickel catalysts and the potential of renewable fuels.
As industries around the globe work to reduce emissions of carbon dioxide, there is also effort to prevent its escape into the atmosphere by sequestering it. These technologies are known as carbon, capture and storage.
Can you mix stainless alloys in the same construction? What guidelines are there for mixing and matching alloys for success? Let’s look at a few cases.
Materials selection for any piece of equipment or a process system is rarely a simple task, unless you are exactly replicating something successful. Often engineers will have a checklist to help them narrow down the choices, eliminating groups of materials that are not suitable for various reasons. Austenitic 300 series stainless steels containing 7-35% nickel will have most if not all of the boxes checked for being suitable where a stainless steel is desired.
Each family of stainless steels has its strengths and weaknesses. Ferritic stainless steels have useful properties – a lower rate of thermal expansion, higher thermal conductivity, strong ferromagnetism and very high resistance to chloride stress corrosion cracking (SCC). When looking at selecting any alloys, it is important to consider all the factors for successful usage.
The duplex alloys are “problem-solving alloys” for good reason, they have been successfully used in many places where carbon steels and standard austenitic alloys have failed. Just like with the austenitic family, there are many different duplex alloys to choose from, with corrosion resistance varying from moderate with the lean duplex alloys to very high with the superduplex alloys.
The selection of an alloy should be guided by careful examination of the needs of the application. Before making a switch, it’s important to fully investigate an alloy’s strengths, weaknesses and applicability to your structure.
The 4th update of the Nickel Institute’s Safe use of Nickel in the Workplace has been published. It has been revised to help companies using nickel keep up with the latest health and environment knowledge of this resource element which is important for a wide range of applications.
Think of the largest cruise ship. Then imagine how much it weighs – just over 100,000 tonnes, in fact. Now think about 500 of those ships, and what they weigh. That is the staggering amount of new electronic waste that we generate every year.
As delegates to the UN COP26 Climate Change conference in Glasgow grapple with the climate crisis, clean energy solutions will be in focus. Although clean energy technologies rely on metals and minerals that are unavoidably energy intensive to produce, the IEA says that the climate advantages of these technologies remain clear.
Even small quantities of nickel in an application can make a big difference to successful deployment.
“There’s a mental hurdle to get over of how inherently gross this could be, but we know that this water is safe, and we stand by our process.”
James E. Churchill believes that telling the history of Monel and renewing the scientific data will empower conservators to educate and preserve key metallurgical heritage.
A new generation of designers, materials specifiers, architects and engineers is being introduced to the wealth of technical information curated by the Nickel Institute. An archive of technical guides and know-how for working with nickel-containing materials, including stainless steel, that has been built over thirty years is now being updated and made freely available.
Ever-tightening sulphur oxide (SOx) emission regulations are increasing the use of marine scrubbers globally. Scrubbers operate in a highly corrosive environment and require the resilience of nickel-containing alloys to prevent failure.
Most nickel production is destined for stainless steel. But a significant 8% is used in the production of alloy steels which are needed to deliver specific characteristics for specialised and often critical applications.
