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.
The ambitious future of India’s rail infrastructure requires prudent investments that ensure its long-term viability. This is where nickel-containing steels play a vital role.
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.
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.
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.
Major economies across the globe are setting climate neutrality targets. But proper measurement and methodologies are needed to provide transparency and common benchmarks when assessing carbon footprint. At a recent event in China, there was general consensus on the importance of adopting a harmonized approach to carbon footprint calculation and disclosure.
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.
“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.
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.
When Courtney Love wrote this she was not thinking about rockets. It is, however, a perfect description of the history of rocketry. Until the Elon Musk revolution.
Space is hard but nickel makes it possible. The United States of America, through the private company SpaceX, imminently expects to regain its independent way into space.
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?
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.
