As the world gears up for the United Nations Climate Change Conference (COP-29) in November this year, nations which are most vulnerable to climate change are launching and executing strategies to mitigate the extreme variability and erratic fluctuations in global weather.
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.
After several years of negotiation between EU institutions, the EU Carbon Border Adjustment Mechanism (CBAM) Regulation was adopted in 2023.
World Food Safety Day on 7 June 2023 draws attention to food standards. Foodborne diseases affect 1 in 10 people worldwide each year, and food standards help us to ensure what we eat is safe.
Just as the EV revolution was gearing up to become consumer driven, there was an increase in raw material prices, semi-conductor shortages and recently a steep rise in electricity prices. At a time of energy crisis, are EVs still a game changer?
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.
Electrification of light-duty vehicles is trending in many parts of the world and is on track to become a consumer driven phenomenon but let’s not forget the heavy-duty vehicles such as trucks and buses.
Even small quantities of nickel in an application can make a big difference to successful deployment.
Food safety starts with rigorous hygiene, and nickel-containing stainless steels are the superior, reliable standard at every link of the food chain.
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.
