Stainless steel continues to deliver a strong and enduring reputation for visual appeal and structural performance in commercial applications.

Perth’s Cockburn Health and Community Facility features over 300m of internal and external stainless steel handrails and balustrades fabricated and installed by ASSDA Member and Accredited Fabricator, Balustrading WA.

The extensive use of stainless steel in the integrated medical and health centre complements the state-of-the-art building and quality services offered to the local community.

ASSDA Sponsors Austral Wright Metals and Vulcan Stainless supplied grade 316 stainlesss steel throughout including for the main vertical balusters, which measure 10mm thick, and are 150mm

Using AS/NZS 1554.6 effectively means rather more than requiring “Weld finishing to AS/NZS 1554.6”. The standard is an effective way to get the finish you want or need on stainless steel structures. This guide should help you to nominate the quality of weld to the standard.

What is this standard?

This standard is for welding any non-pressure stainless steel equipment and when it was first drafted in 1994, its structure followed that of Part 1 dealing with carbon steel. A major revision in 2012 removed redundant text, expanded the good workmanship guidelines and brought the weld assessment and finishing processing

The Australian Museum's 2015 facelift saw its new entrance made with a contemporary glass curtain wall feature supported by stainless steel.

The design brief for the architecturally stunning entrance hall feature was a structure that conveyed the image of a modern and transparent institution. Designers Neeson Murcutt Architects and Joseph Grech Architects drew inspiration from the museum’s collection of gemstones for the new façade, resulting in a double-glazed window set against coloured glass panes.

ASSDA Member SGM Fabrication & Construction fabricated the stainless steel frames to support the glass facade as part of the museum’s redevelopment plan. This transformation saw

Stainless steel has brought life to a unique food precinct located in a recently opened premium office tower in Brisbane City's Golden Triangle.

Developed and constructed by Grocon, 480 Queen Street’s sustainable and eclectic design boasts a 6 Star Green Star and a 5 Star NABERS rating. The building’s food gallery, otherwise known as Room 480, is located on level 2 and capitalises on the stunning views of Brisbane River and Story Bridge to deliver a restaurant style experience and retreat for diners.

Complementing this space is a suspended stainless steel sculpture, designed by local architecture and interior design practice

Over 17 tonnes of stainless steel has been used for the upgrade of a premier meat processing plant to support the growing local and global demands of Australian red meat supply.

The Australian Lamb Company (ALC) currently exports lamb to more than 60 countries worldwide, and recently secured a 10-year contract to process lamb for Coles supermarkets in eastern Australia.

ALC’s multi-million dollar investment to support demand and increase production capacity included the expansion and upgrade of its meat processing operation in Colac, Victoria.

Water authorities tackle water shortages with stainless steel.

Water is a fundamental human need. It is central to our lives, from what we drink, to what we use in washing ourselves, our clothes and a multitude of other uses. Safe, clean and palatable water comes at a price though, and when leaks occur in distribution systems, additional costs are incurred as even more water must be found and treated. Security of water supply is a prerequisite for sustainable growth and dealing with leakage is a universal challenge. To combat the scourge of leaks, a number of water distribution authorities across

Brisbane’s iconic Story Bridge is sporting increased safety measures with the application of innovative stainless steel products and laser-fusion technology.

 The 76-year old heritage-listed cantilever bridge now incorporates three-metre tall, stainless steel safety barriers on its pedestrian walkways, as a result of an outstanding collaboration between multiple project stakeholders. Completed in December 2015, the $8.4 million project was led by design and construct head contractor, Freyssinet.

The design brief was to develop an anti-climb structure that was both functional and aesthetically appealing, whilst ensuring the heritage values of the bridge were maintained.

This presented a number of engineering challenges, including

Connections are vital

Any visit to a dairy, beverage or food processing plant will drive home the critical importance of the connections between the tanks, mixers, driers, pumps, etc. The image above (courtesy of TFG Group) showing an image of a brewery is a typical example. These tubes and/or pipes carry the process materials, the heating or cooling or wash water, gases, and also dispose of the wastes.

Getting the right standard

Except for high pressure or very aggressive environments, most tube is rolled into shape and welded longitudinally. For mechanical or structural service such as columns or handrails,

A modern and innovative design using coloured and textured stainless steel has left an impressive statement on an Adelaide streetscape.

South Australia’s premier shopping district Rundle Mall underwent a full makeover from 2012-2014 as part of the Adelaide City Council’s initiative to revitalise the precinct.

Part of this redevelopment included a redesign of the facade of a commercial tower at 80 Grenfell Street, housing the Adelaide headquarters of the Bendigo and Adelaide Bank.

Design practice HASSELL delivered an iridescent façade design using coloured stainless steel cladding, supplied by ASSDA Member Steel Color Australia. The extent of the façade referred

Stainless steel has helped deliver improved environmental performance and increased efficiency for a major food production company.

In 2014, Australian agribusiness GrainCorp announced a $125 million investment in a consolidation strategy to integrate its GrainCorp Foods’ manufacturing operations, including the relocation of its Brisbane plant to the existing West Footscray facility in Victoria. This move effectively terminates the use of its coal-fired equipment, giving GrainCorp Foods the opportunity to invest in efficient and environmentally sustainable technology and significantly reduce its carbon footprint.

As a result, GrainCorp Foods’ West Footscray operation commenced its expansion and upgrade in 2015 to deliver a

The spirit of the Anzacs is evoked in a new architecturally stunning, stainless steel walkway that unfolds around Newcastle’s cliffs and links Strzelecki Lookout to Bar Beach.

 The much-anticipated Newcastle Memorial Walk opened on 24 April 2015 on the eve of the Anzac centenary, and features spectacular 360-degree views of Newcastle city and coastline.

The 450m raised walkway forms part of Newcastle City Council’s ‘Bathers Way Project’, a $29 million foreshore development and revitalisation program to link Merewether Beach with Nobby Beach via a coastal walk. The total cost of the walkway was $4.5 million, $3 million of which was

Welding the common austenitic stainless steels such as 304 and 316 to each other or themselves is routine and the easiest of fusion welding.

Nevertheless, there are many situations where it is necessary to weld stainless steel to carbon steel. Two common examples are balustrade posts attached to structural steel or doubler plates connecting supports to stainless steel vessels. There are differences in physical properties such as thermal conductivity and expansion, magnetic properties, metallurgical structure and corrosion resistance, which all require attention. This article outlines the necessary procedures for satisfactory welding, including reference to standards, and explains the necessary precautions.

Stainless steel is the material of choice for subsea hydraulic and control line applications because of its excellent corrosion resistance, material strength benefits and weldability.

 Subsea production in the oil and gas industry involves offshore, in situ equipment to facilitate the exploration, development, production and transportation of energy reserves from underwater fields. It is a viable form of oil and gas production, providing economic, productivity and environmental benefits.

Perth-based ASSDA Member and Accredited Fabricator Diverse Welding Services (DWS) recently completed detailed design and fabrication works on two major subsea projects operated by multinational oil and gas exploration and production companies.

‘Under the Sun’ is a 1300kg, 6.5m diameter suspended stainless steel sculpture that embodies a symbol of the moon floating over the earth, and casts filigreed shadows under the sun. It is an inspiring architectural piece featured at the entrance of Stockland’s Point Cook Town Centre in Victoria, and was completed in 2014 as part of the shopping centre’s $20 million revamp.

 The sculpture is an expression of the relationship between the moon and the sun, opening a space for visitors to reflect in moments of perspective and wonder. The sculpture’s concept was also inspired by the traditional feminist symbol

The magic of a clear night sky filled with stars has inspired many creative souls. Now, through a collaboration between science and art, a stainless steel sculpture installed at the Australian National University in Canberra brings new depth to the connection between ourselves and the stars above.

The 4 metre diameter, mirror-polished stainless steel sphere (called UNA), which sits in the science precinct at ANU, is so much more than first meets the eye. Designed by UK artist Wolfgang Buttress, UNA features 9,100 laser-cut perforations, which were mapped in collaboration with ANU astrophysicist Dr Daniel Bayliss.

Stainless steels resist corrosion because they have a self-repairing “passive” oxide film on the surface. As long as there is sufficient oxygen to maintain this film and provided that the level of corrosives is below the steel’s capacity of the particular material to repair itself, no corrosion occurs. If there is too high a level of (say) chlorides, pitting occurs. As an example, 316 works well in tap water (<250 ppm) all over Australia, but will rapidly corrode in seawater because seawater has very high chloride levels (20,000 ppm).

If there is not enough oxygen

Brisbane's New Farm Riverwalk is one of the city's beloved icons. Originally constructed in 2003, the Riverwalk was used daily by over 3000 cyclists, pedestrians and runners before it was washed away during the 2011 floods.

After a construction period of nearly 18 months, Brisbane City Council’s re-imagined New Farm Riverwalk has now opened to the public, connecting New Farm to the Brisbane City via the Howard Smith Wharf Precinct.

Engineered by Arup, the Riverwalk has a design life of 100 years and sits 3.4m above mean sea level on robust piles.

Critical to its design and life expectancy is

A grand ballroom demands high impact aesthetics combined with maximum functionality, both of which have been supplied in spades at the recently refurbished RACV Royal Pines on Queensland's Gold Coast

Central to Stage 1 of the award-winning refurbishment is a 55 metre long and 5 metre high floor-to-ceiling glass wall anchored and framed by nearly a tonne of stainless steel wire rope and fittings. The wall ensures an impressive visual impact, as well as enabling a flood of natural light, a stunning view, and flexible exhibition options.

ASSDA member Australian Pickling & Passivation Service (APAPS) and ASSDA sponsor Sandvik Mining & Construction have been central to the expansion of a coal export port in North Queensland.

With Queensland coal exports forecast to increase to 250mtpa by 2015, the strength and durability of the state’s expanding coal transport infrastructure and rail systems is critical to ensuring export capacity.

This recent expansion required the manufacture of 300 three-piece conveyor frames using 40 tonnes of 316 grade stainless steel, specified to foil the port’s exposure to wind, rain, salt spray and abrasive dust.

Sandvik Mining & Construction manufactured the conveyor

Almost 7 years after former Nickel Institute Director Dr David Jenkinson's 2006 Technical Bulletin, ASSDA's technical expert, Dr Graham Sussex, revisits the CrMn grades of stainless steel.

BACKGROUND
The majority of stainless steel is drawn from the austenitic family because these grades are readily formable, weldable and tough. These chromium-nickel (CrNi) and molybdenum-containing grades were traditionally grouped under the 300 series banner.

However, driven by the increased price of nickel several years ago, there has been renewed interest in lowering the nickel content of austenitic grades while maintaining the austenitic crystal structure. This is achieved by using combinations of higher
