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?
Mark Mistry and Marco Vallini argue that for the EU Critical Raw Materials Act to fulfil its promise to address the energy transition, industry needs planning security for both ‘critical’ and ‘strategic’ raw materials.
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.
Steven Verpaele, the Nickel Institute’s Industrial Hygienist explains how a new workplace exposure collection tool and database system will help prevent occupational diseases and contribute to creating a health and safety culture at the workplace.
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 proposed Regulation will introduce a wide range of sustainability requirements and promote the recycling of key battery raw materials like nickel. EU legislative work is entering a crucial phase.
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.
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.”
Steven Verpaele, the Nickel Institute’s Industrial Hygienist explains the different ways that the work he leads is helping to contributing to the culture of occupational safety and health that respects the right to a safe and healthy working environment at all levels.
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.
