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.
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.
What is a “sustainable product”? Is it more sustainable to continue using my old washing machine or to buy a new, more energy efficient one? Are single use products always unsustainable? What criteria should I use to judge whether a product is sustainable or not? What measures can we take to promote sustainability in products?
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.
In 2021, China recorded the strongest growth in the EV market with around 3.2 million EVs sold. This was an increase of 2 million EV units compared to 2020 which was more than the combined increase of all other regions taken together.
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.
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.
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.
As electric vehicles (EVs) trend from being niche to mass scale and the lines between EVs and their combustion engine (ICE) counterparts get blurred in terms of usability, consumers, automakers, governments and fire departments continue to have some apprehensions.
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.
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.
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.
Should we be worried about there being enough nickel to supply the transition to electric vehicles and cleaner energy sources? Given its wide range of uses in important existing and emerging technologies, this is a frequently asked question.
