Ditch the plastic! and pick up a Stainless Steel straw instead.


Plastic straws and cotton buds could be banned in England as part of the government's bid to cut plastic waste. Ministers pointed to one estimate that 8.5bn plastic straws were thrown away in the UK every year. The prime minister said plastic waste was "one of the greatest environmental challenges facing the world". And Theresa May will urge leaders at the Commonwealth Heads of Government Meeting, which began earlier, to follow the UK's lead in tackling the problem.

But there is a simple alternative to these plastic straws and that’s Stainless Steel straws. Durable and lightweight, Stainless Steel metal straws won’t corrode, rust or break.

How to make 4 x harder ‘Super Stainless Steel’ with higher surface hardness, wear resistance and fatigue strength.



Higher surface hardness, wear resistance and fatigue strength

Stainless steel is the material of choice in various industries where corrosion resistance is of utmost importance, take for instance parts that are exposed to harsh environments. However, this highly favourable property does not always go hand in hand with high surface hardness, wear resistance and fatigue strength.

Most heat treatment methods cannot be easily applied to stainless steels to improve its properties. In particular, surface hardening of stainless steel by nitriding and nitrocarburising in the conventional temperature range of 500 to 1000 °C is highly detrimental to its corrosion properties. A possible solution is implementing processes that enable lower-temperature surface hardening of stainless steel.

The EU-funded project PLASSTEEL has developed an advanced process for low-temperature surface hardening of stainless steel that allows accurate tailoring of the material properties. The new heat treatment process can be applied to all ferritic, martensitic, austenitic and duplex grades, imparting the material with unparalleled levels of wear, fatigue and corrosion resistance.

Increasing hardness at lower temperatures

Based on more than 40 years of experience, IONITECH LTD has developed a plasma nitriding/nitrocarburising furnace achieving excellent temperature uniformity on the whole working area. "The novel plasma nitriding furnace also eliminates the possibility for the 'hollow-cathode' effect. This local overheating might lead to temperatures above those needed for the PLASSTEEL process that will in turn lead to chromium carbide and chromium nitride precipitations on the grain boundaries of the steel. These areas will have higher surface hardness but will also be susceptible to intergranular corrosion," says leading research and development specialist Alexander Varhoshkov.

The PLASSTEEL process is based on plasma technology and composed of a solution nitriding and nitrocarburisation process at temperatures below 500°C that enriches the surface layer of a workpiece with nitrogen and carbon. The carbon-containing gas added in nitrocarburisation can be methane, propane or natural gas. Its content varies from 2 to 10 % in the gas mixture. The treatment step can last from several minutes up to 20 hours, depending on the workpiece material and the requirements regarding the layer depth.

Throughout the project, several types of stainless steels were processed and tested. Depending on the percentage of the alloying elements in these steels as well as other properties, results slightly varied. "Some of the alloying elements made diffusion of the carbon atoms harder and slower, thus leading to small differences in the diffusion layer and surface hardness. Nevertheless, in any case, the goal was to improve the wear properties of all types of stainless steel, while also retaining their corrosion properties," says Dr. Varhoshkov.

A process as true as steel

Most surface-hardening techniques diminish the original corrosion resistance of stainless steels. IONITECH's advanced new process and plasma nitriding furnace show that this is no longer the norm. "This shortcoming is successfully circumvented by this excellent plasma nitriding furnace that provides precise control over the material properties," continues Dr. Varhoshkov.

Working at low temperatures provided a remedy for dissolving nitrogen or carbon into stainless steel without the formation of chromium nitrides or carbides. Project partners succeeded not only in increasing the surface hardness of the parts by 4 times, but also in improving adhesive and abrasive wear, and the tribological properties of the metal as well.

Eat your heart out Game of Thrones! The fantastical Stainless Steel creations of Kevin Stone


Based in Chilliwack, British Columbia, artist Kevin Stone specialises in creating gigantic fantasy art sculptures made from stainless steel. Each mirror-polished piece is constructed with hundreds of highly reflective metal components, making them durable pieces of outdoor metal art that can withstand the harsh elements and glitter majestically in the sunlight.



Having previously worked as a professional welder, Stone combined his practical knowledge with his creative imagination by becoming an independent artist in 2005. In 2006, he unveiled Power and Authority, an incredible, 20-foot-tall bald eagle with a massive 31-foot wingspan. Reimagining his feathered muse once again, Stone’s second eagle sculpture, Power of Flight, is even larger and more detailed than the first. His latest piece, created in 2017, also depicts an eagle in a slightly smaller—but equally impressive—scale.


Growing up in British Columbia, Stone developed an early fascination with the particularly regal bird of prey. He reveals, “I have always found the bald eagle to be an inspiration to me both artistically and spiritually. They signify incredible power and dominance in their environment, and yet at the same time are the most graceful, beautiful, and elegant species of bird I have observed.”

Each piece is extremely labor intensive and time-consuming, as they are all cut and polished by hand. In the case of the incredible 6,000-pound, 12-foot-high, 35-foot-long Chinese Imperial Water Dragon sculpture, Stone spent more than 12,000 hours perfecting his masterpiece. Stone says, “My sculptures are designed to attract attention, create emotion, add beauty and style to their environment, and become a fabulous focal point.”

How Stainless Steel Wool is helping to treat wastewater and also generate free electricity


Microbial Fuel Cells (MFCs) are bio-electrochemical devices that use the power of respiring microbes to convert organic matter into electrical energy. Thus, they can help treat wastewater and also generate electricity. Realising the vast potential these cells have, scientists are finding ways to improve their performance and efficiency. In one such effort, scientists from the Indian Institute of Technology Bombay (IITB) have demonstrated how stainless steel wool, coated with conducting polymers, could be used in microbial fuel cells to improve their performance.


Microbial fuel cells work by the action of microorganisms, which digest organic matter. In the presence of oxygen, this process produces carbon dioxide and water. However, in the absence of oxygen, as seen in sewage treatment plants and industrial effluent discharge, the process produces carbon dioxide, electrons and protons. Electricity is produced when these electrons are captured using electrodes. Hence, one way to improve the performance of the fuel cells is to use a better material for electrodes.

In this study, researchers have demonstrated, for the first time, the use of low-cost Stainless Steel wool as an efficient material for one of the electrodes (anode) used in fuel cells. They found that using stainless steel wool resulted in a 70% increase in power density (the amount of power per unit volume), as compared to stainless steel tubes, when used as an anode. Further, they observed that steel wool, when coated with conductive polymers like polyaniline and polypyrrole, performed twice as better than plain steel wool.

With more suitable materials and efficient design, MFCs could be our solution to waste management with energy generation in the future.

During the day the sports facilities are used for education by the Haagse Hogeschool (The Hague University of Applied Sciences) and ROC Mondriaan, and for performance training by a variety of sports organisations. During the evening and at weekends the facilities are made available to the public.

The campus will also serve as a ‘knowledge centre’ for sports and exercise, becoming a part of the Center for Elite Sports and Education for the metropolitan area of The Hague-Rotterdam. A number of organisations will use the campus to carry out research alongside the education programmes based on site.


Architect’s view

Our design solution is an interpretation of the brief to embody within the campus the principles of ‘motion and activity’. This is expressed externally in the fluid movement of the elevational treatment. At ground level, the curved form of the plan is expressed by a simple plinth constructed from textured precast concrete panels. The upper part of the elevation is expressed as a metallic ‘ribbon’ that narrows and twists to reveal glazing on the elevation. Constructed from brightly polished Stainless Steel, the dynamic ribbon changes colour with different lighting conditions and cloud patterns, as well as reflecting the animation of its natural setting.

Refuel your electric car in minutes with the help of Stainless Steel


A new form of supercapacitor based on soft contact lens technology could allow electric cars to be refuelled as quickly as petrol ones.

Hertfordshire-based firm Superdielectrics unveiled the breakthrough 14 months ago, and has spent the intervening period verifying and improving the invention in conjunction with the Universities of Bristol and Surrey.

Existing supercapacitors have practical capacitance values of 0.3 farad per square centimetre, but researchers from the universities were able to achieve results of between 11 and 20F/cm2 when using specially treated stainless steel electrodes.

If these values can be replicated in production, supercapacitors could potentially achieve similar or greater energy densities than lithium-ion batteries, which would be a potential game changer for electric vehicles.

Currently, it can take up to eight hours to fully recharge an electric car, or at least half an hour with the fastest rapid-charging technology. This development could shorten that time to minutes, according to the researchers.

“These results are extremely exciting and it is hard to believe that we have come so far in such a short time,” said Brendan Howlin, senior lecturer in computational chemistry at the University of Surrey. “We could be at the start of a new chapter in the technology of low-cost electrical energy storage that could shape the future of industry and society for many years to come.”

The polymer builds on work by Donald Highgate, director of research for Superdielectrics, that started in the late 1970s with extended-wear soft contact lenses. “The present work, if it can be translated into production, promises to make rapid charging possible for electric vehicles, as well as offering a low-cost method of storing the transient output from renewable energy systems,” he said.

1,700-tons of Stainless Steel soaring 599m into the sky


Ping An International Finance Centre, disappearing into the clouds of Shenzhen’s stormy heavens, is just the latest, (almost) greatest in the Middle Kingdom’s super-tall skyline. The second tallest tower in China serves the country’s second largest insurance company, rising 115 floors and 599 meters into the sky. A needle would have put it above the Shanghai Tower, but that would have pierced the paths of passing planes and was wisely scrapped. Now a gleaming pyramid crowns the tower.



Started in late 2009 (and delayed one year when inspectors found corrosive sea sand in the concrete), in 2014 it shot up at an astonishing rate of one story every four days.

Construction finished in 2016, but the Council on Tall Buildings and Urban Habitat waited until 2017 to certify it as fourth tallest in the world. It was the second year in a row that Shenzhen had the tallest new building (and the most super-talls), in a building boom that sees China with over half the world’s new skyscrapers. Along with the Shanghai Tower, Guangzhou CTF Finance Center, Shanghai World Financial Center and Hong Kong’s International Commerce Center, five of the world’s 10 tallest buildings are Chinese.





But though its American architects, Kohn Pedersen Fox Associates, designed it to retain its sheen in the face of sea-born storms – thanks to a streamlined shape deflecting winds by 35 percent and a 1,700-ton Stainless Steel frame (the world’s heaviest) that resists corrosion and disperses lightning strikes – it may be China’s hunger for height that knocks Ping An off its pedestal. Already there are plans for a Suzhou Zhongnan Center (729 meters) and an unnamed super-tall in Shenzhen’s Luohu District (739 meters) that will dwarf our giant.
