Global industry supply chain pressure

Global industry supply chain pressure

Simon Pepper, Managing Director of ASSDA Member SILA Global, provides an important update on shipping and logistics in the Australian supply chain.

To say the last few years have been unstable, uncertain, difficult, and perturbing would be an understatement. The worldwide impact and far reach of industry issues experienced remind us that we truly are a global economy, and an event on the other side of the world can severely affect the Australian supply chain. We are not out of the woods yet. 

Problems that occurred last year with freight rates, space constraints, rollovers, port closures and other delays are beginning

Kingsford Smith Drive: Stainless for the long run

Kingsford Smith Drive: Stainless for the long run
Brisbane’s Kingsford Smith Drive upgrade saw Australia’s largest use of stainless steel reinforcement bar to date, transforming the structural performance of one of the city’s busiest roads.  

An initiative of Brisbane City Council and designed and constructed by Lendlease, the Kingsford Smith Drive upgrade involved widening the 7km road from four to six lanes between Theodore Street at Eagle Farm and Cooksley Street at Hamilton. This was achieved via a retaining wall built between 10m to 15m out into the Brisbane River. As a major road corridor, Kingsford Smith Drive links the Brisbane CBD to Brisbane Airport, the Port of

Raising the standard with stainless steel

Raising the standard with stainless steel

Water quality plays a crucial role in the decontamination and reprocessing of reusable medical devices, and stainless steel has helped facilitate the standard required for their sterilisation. 

The release of AS/NZS 4187:2014 Reprocessing of reusable medical devices in health service organisations requires hospitals across Australia to comply with a range of stringent new requirements consistent with European and global standards for sterilisation processes. Its aim is to ensure reusable medical devices are adequately cleaned, disinfected and sterilised to protect patients and prevent infection.

Water quality is critical for sterile processing, and one requirement of the revised standard includes the replacement of non-compliant cleaning,

Common misconceptions about stainless steel

Common misconceptions about stainless steel

Everyone knows that stainless steel resists corrosion, but beyond that, an amazing range of half-truths and exaggerations have evolved - often misleading and sometimes simply wrong. This article examines some of the more common myths, explains why they are wrong, and more to the point, provides correct information.

MISCONCEPTION: There are only two types of stainless steel, 304 and 316. 

FACT: There are hundreds of stainless steels from high strength duplex 2205 supporting bridges, to furnace ducts of ferritic 3/5Cr12 and the high temperature 310, but the most common types are the austenitic 300 series.

Stainless steels were invented a little over

Comparisons of hot and cold formed stainless steel

Comparisons of hot and cold formed stainless steel

When comparing hot and cold formed stainless steel, the first question you would ask yourself is: are there any chemical differences between the two? ASSDA has previously published articles on the various surface finishes including the few hot and multiple cold finished processes, however this article concentrates on the differences. 

Since the 1970s, most stainless steel is produced by melting in an Electric Arc Furnace (EAF) and then the molten stainless steel is transferred to an Argon Oxygen Decarburisation (AOD) vessel or, less commonly, a Vacuum Oxygen Decarburisation (VOD) vessel. These processes control impurities such as carbon, sulphur, nitrogen, hydrogen

Stainless steel – a mainstay in water assets

Stainless steel – a mainstay in water assets

A mainstay in the processing of sewage water in water recycling applications, stainless steel once again plays a critical part in working towards a sustainable future.

Western Water Treatment Plant (WWTP), south of Werribee in Melbourne’s Western District, is a critical asset responsible for processing around half of the city’s total sewage. The process requires a massive footprint, where a series of large lagoons use anaerobic (without oxygen) and aerobic (with oxygen) bacteria to sequentially break down and clean the feed water of solids and gases. The resultant recycled water is used for multiple non-drinking purposes, including irrigation and firefighting.

Seven ways to prevent tea staining of stainless steel

Seven ways to prevent tea staining of stainless steel

When used properly, stainless steel enjoys a strong and enduring reputation for visual appeal and structural integrity in a wide range of applications and environments. But, like all materials, stainless steel may become stained or discoloured over time, impairing the overall look. This brown discolouration - tea staining - has been identified in coastal applications in Australia and overseas.

In the late 1990s, the newly formed ASSDA Technical Committee researched the reasons for the brown discolouration. ASSDA’s work, in collaboration with the International Molybdenum Association, led to guidelines published in 2001 explaining the causes and remedial techniques. The work was
