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.
Solar farms are blooming in fields across the globe and producing a new crop: solar energy. Photovoltaic (PV) systems made up of solar panels, are fast becoming the most recognisable of renewable energy technologies.
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.
The sudden failure of a building or bridge is mercifully a rare event, thanks largely to international or national standards: structures are designed in accordance with a design standard, using products conforming to a product standard and manufactured using techniques and to a quality level defined in a construction standard.
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.
Awareness about robustness and durability of bridge design has grown since Morandi’s time. The new San Giorgio Bridge (its successor) in Genoa was designed by Renzo Piano and inaugurated in 2020.
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.
While it may require an initial higher investment when compared with other materials, stainless steel’s unique properties deliver long-term performance and economic benefits including minimum downtime, reduced maintenance costs and reduced environmental impacts.
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.
Nickel-based alloys and nickel-containing stainless are playing key roles in an emerging source of renewable energy known as thermal solar plants or concentrated solar power (CSP). Their use has enabled the industry to overcome challenges in heat transfer and thermal storage technology.
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.
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.
If you’re like me and predictive text has led to some awkward if not amusing moments, you might be sceptical about Artificial Intelligence (AI). But its achievements are already overwhelming and changing, even protecting, our lives in many sectors.
New advances in the use of Artificial Intelligence have the potential to speed up the process of alloy development.
Food safety starts with rigorous hygiene, and nickel-containing stainless steels are the superior, reliable standard at every link of the food chain.
Around two-thirds of today’s buildings will still be around in 2050, and by 2060, the world is projected to add 230 billion m² of buildings - an area equivalent to the entire current global building stock. What can the building and construction sector do to reduce the environmental burden of buildings?
Nickel’s role in enabling technologies is not always common knowledge. Yet its versatile properties present great opportunity for the nickel industry.
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.
