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.
Nickel-based catalysts are key to supplying energy to power our transportation of goods and people, whether by land, sea, or air.
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.
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.
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.
The many new and innovative applications of hydrogen as fuel show great promise for a greener future.
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.
The present-day principal driver in the Li-ion industry is the large batteries required for electric vehicles. Due to the size of these batteries and the relative growth of electric vehicles it is predicted that the total Li-ion energy capacity will exceed one tera watt-hour by 2030. This anticipation for a dramatically rapidly expanding industry has stakeholders all along the value chain very motivated to be ready.
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?
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.
