Stainless Steel for the People

 


Posted 30th November 1994

 

In late 1989 my partner Eric Kuhne was asked by Stuart Homery of Lend Lease to come out to Australia to work on the ground plane and lobby of a 28 storey office building about to start construction in Sydney. This building is the first of three towers and some foreshore development on the edge of the city centre at Darling Harbour. Our involvement in phase one led to the replanning of ground plane, lobbies, forecourt area, and addition of a large garden between the three towers, and a complete rework of the fore-shore

Chlorine and chloride: Same element, very different effect

Chlorine and chloride: Same element, very different effect

Posted 1 July 2007

Choosing the correct grade of stainless steel for a tank, pipe or process vessel requires (at the very least) information about the temperature, pH and chemical composition of the contents.  One of the most important items of the chemical composition is how much chloride (salt) is present.  Analysis reports often give the concentration as milligrams per litre (mg/L) or sometimes as parts per million (ppm) of Cl.  However, Cl is also the symbol used for the element chlorine.

So what is the difference?

Chlorine is a poisonous, yellowish green gas which readily dissolves in water to

Stainless Steel Cookware....

Safe, Hygienic and of Little Concern to People with Nickel Sensitivity


Posted 31st July 1993

Over the past few years stainless steel cookware has undergone scrutiny to determine its safety as a product for use by people with nickel contact dermatitis and it has been shown to have no ill effect.

Early in 1993 Mr G. Norman Flint visited Australia and described current thinking in Europe concerning the use of stainless steel cookware by nickel sensitised people. Mr Flint is a consultant to the Nickel Development Institute based in the United Kingdom and is responsible for presenting nickel's case in

Stainless Steel for a Revolutionary Heat Exchanger


Posted 31st July 1993

Stainless steel plates are the core component of a revolutionary brazed plate heat exchanger manufactured by Melbourne firm Multistack International Limited.

The heat exchangers are designed to replace conventional gasketted-plate and shell-and-tube designs. After pioneering work was conducted in Europe in the late 1970's Multistack have achieved higher efficiencies and longer operational life after an Australian development program of several years and "many millions of dollars".

Type 316 stainless steel plates stacked on top of each other form the basis of the heat exchanger's design. Each plate is embossed with a channel formed under high pressure,

Life Cycle Costing and Stainless Steel

Life Cycle Costing and Stainless Steel

Posted 31 July 1993

Life Cycle Costing (LCC) has long been used in planning for reliability and maintenance for complex engineering systems in defence, airline, railway, offshore platform, power station, and other applications.

A basic attribute of stainless steel is the ability to provide long-term perfor-mance with a minimum of downtime and cost associated with maintenance. As a result LCC is of particular importance to the stainless industry.

Whilst the mathematics of LCC can be quite complex the International Chromium Development Association (ICDA) has developed an IBM or compati-ble PC program on floppy disk which can be easily applied to

The growing demand from China and the rest of the developing world has driven up the price of alloying elements added to stainless steels.  Over the last five years nickel prices have risen to ten times what they were.

Chromium and molybdenum have also risen strongly, and the price of stainless steel scrap – which steelmakers use extensively – has soared.  Inevitably, stainless steels have also

The work of Anna Eggert is not new to ASSDA, or to those familiar with the 2005 Reference Manual where her pieces entitled “Belinda’s dress” featured on the cover.

anneeggertTwo years on, Anna’s love of stainless steel continues, as she begins work on a new project which has seen her nominated for the 2007 McClelland Award.

The work, which will be put forward for a chance at the $100,000 prize money, is similar to that shown, and again uses stainless steel mesh.

“Mesmerized” is an eight piece artwork  continuing an investigation into the female identity.  In

Bruce Harding is not the first person to be frustrated by rusty cast iron hotplates and grills on his barbecue – the difference is that he did something about it.

bbqDrawing on more than 25 years experience in the stainless steel industry, Mr Harding and his team at Equipment Tech Pty Ltd have developed a range of stainless steel hotplates, grills and baking dishes (sold under the name of Topnotch) that can be retro-fitted to almost any barbecue.

The company uses austenitic T304 and ferritic stainless steels, which are mostly supplied by ASSDA members Sandvik and Atlas Specialty Metals.

Never has there been a time in Australia when water preservation was so critical.  As populations rise and dam levels fall, the importance of treating and reusing water has become not a question of “if” but a question of “when”.

bundambaThe construction of Bundamba Advanced Water Treatment Plant (BAWTP) west of Brisbane is aimed at alleviating pressure on South East Queensland’s existing dams and waterways by providing an alternate water supply for end users in the region, initially Swanbank power station.  

The project has had great flow on benefits for the Australian stainless steel industry as infrastructure requirements point

Testing for grade confirmation

Testing for grade confirmation

Raw material price fluctuations and increasing demand for stainless steels have driven demand for lower cost alloys as alternatives to the traditional “300” series steels. This has been met through a range of existing and new, innovative steels with different properties, performance and availability broadening the range of alloys that might be found in the market. But as with the traditional stainless steels you can’t tell what they are by looking at them.

This article describes most of the range of test methods available for grade confirmation. The method used depends on the budget, size of job and the potential

Subwharfyen Steels Your Imagination

Subwharfyen Steels Your Imagination

A childhood spent yacht racing was Newcastle artist Braddon Snape’s inspiration for his intriguing new piece entitled The SubWharfyen at Darling Harbour.

“I was always surrounded by beautifully machined or crafted stainless steel rigging and equipment,” he said. So when Sydney Wharf commissioned Mr Snape to create a large-scale work depicting the relationship between people and the sea, stainless steel seemed like a natural choice.

Mr Snape’s experience in working with hardy materials and a highly evolved visual language proved a winning combination. The finished product is a great success as a premium contemporary development for the area.

Changing costs of alloying elements

Changing costs of alloying elements

Sustained economic growth in China and the rest of the developing world has seen the demand for all the metals grow faster than the minerals industry can develop new mines and smelters.  The result is soaring prices for metals, and for coal and oil.

For a country like Australia - a big supplier of metals - it’s good news, and we have all enjoyed the benefits of the minerals boom. But those of us in the stainless steel industry have seen prices increase markedly, and it has been hard to cope with.  We live in interesting times.

The $10 million stainless steel revamp of Melbourne’s Bourke Street Mall has certainly lived up to its original purpose, providing a durable, clean and simple linear theme.

In 2006, inspired by success stories of nearby stainless street furniture, the City of Melbourne council conducted a life cycle costing analysis – with astounding results.

City of Melbourne Industrial Designer Marika Mulqueen said stainless steel ensured low maintenance costs and design flexibility.

“Using stainless steel over powder coated steel significantly reduces ongoing maintenance costs. A comparison found that while stainless steel can initially cost more, over a 20 year period maintenance costs

Stainless to reduce greenhouse gas emissions

Stainless to reduce greenhouse gas emissions

To overcome environmental concerns around landfill, Perth’s largest waste management authority, Mindarie Regional Council, is building a facility for the 70 per cent of household waste that is organic material and can be composted.

The $80m building is due for completion in 2009 and will save on landfill, reduce greenhouse gas emissions, and will produce a rich organic matter that may be added to Perth’s sandy soil.

The new composting facility, to be built using a prize-winning technology developed by Canadian firm, Conporec, comes at a time when the ongoing feasibility of landfill in crowded cities is questionable.
