The global life cycle of stainless steel

The global life cycle of stainless steel
Minimising mining (primary production) and maximising recycling (secondary production) are core principles of sustainable resource management. Consequently, there is an increasing interest in quantifying the material life cycle of stainless steel and its efficiencies from production to fabrication, manufacturing, use, recycling and, in some cases, disposal.

In 2006, Team Stainless and Yale University started the first project to quantify stainless steel stocks and flow cycles. In 2022, The Karlsruhe Institute of Technology made a more detailed analysis of 2019 data covering 50 countries, territories, and regions.

Stainless steels: A sustainable solution for more than a century

Stainless steels are procured

Stainless steel for water supply

Stainless steel for water supply
For years, the plumbing industry has been dominated by materials such as galvanised mild steel, copper, and plastic. However stainless steel is quickly emerging as a standard construction material in various water supply applications.

Stainless steel offers a multitude of benefits, including corrosion resistance, hygienic properties, strength, long-term performance, excellent hydraulic conductivity, and the ability to withstand high pressure and temperature requirements. It has found its place in diverse applications, from desalination plants and reverse osmosis water treatment systems to water supply for high-rise buildings and domestic tapware. Stainless steel provides a safe and sustainable solution throughout the entire lifespan

Stainless steel for indoor swimming pools

Stainless steel for indoor swimming pools
Stainless steels are almost universally used around indoor and exterior pools for railings around or into the water, fixtures, furniture, grills, etc. The finishes are bright and readily cleanable for hygiene and are resistant to staining or corrosion by the chemical treatments required for the maintenance of public health.

This article discusses the unexpected problem (and the solutions) that showed up in the 1980s because of the changing design and operation of indoor heated and chlorinated swimming pools when combined with the increased use of stainless steels as structural supports in the ceilings over pools. The problem: 304/316 stainless steel

The benefits of stainless steel for brewing beer

The benefits of stainless steel for brewing beer
Australia is in a craft beer renaissance. The materials used in beer production has evolved over the years, and today, stainless steel is the material of choice and industry standard in modern brewing. Let’s look at some of the benefits.

 
Corrosion resistant

Stainless steels are excellent combatants of corrosion. This resistance to attack is due to the naturally occurring chromium-rich oxide film formed on the surface of the steel, which self-repairs in the presence of oxygen.

With the correct selection of alloys and application of good design principles and proper fabrication practices, stainless steel equipment will perform successfully. 300-series

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.

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. 

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.

Stainless Steel: Sustainability and Life Cycle Costing

Stainless Steel: Sustainability and Life Cycle Costing

Humanity’s use of materials has progressed over the millennia from natural resources such as plants and stone to manufactured materials such as ceramics, metals and plastics with a corresponding increase in consumption of energy and materials – and increasing waste production. In parallel, the world’s consumers have grown exponentially from about 1 billion in 1800, to 7.6 billion in 2018 and a predicted 9.8 billion in 2050 – all demanding more infrastructure, facilities and resources to support the expectations of higher standards of living. This has led to an increasing realisation that green production, recycling, waste reduction and more efficient use

Ferritic Stainless Steels

Ferritic Stainless Steels

Ferritics account for approximately 25% of stainless steel use worldwide. The name arises because these alloys have similar properties to carbon steels when they are bent or cut and, unlike the well-known 304 and 316 austenitic grades, ferritics are strongly attracted to a magnet.

Thermal Expansion and Design of Stainless Steel Fabrications

Thermal Expansion and Design of Stainless Steel Fabrications

Either while being welded or glistening in the summer sun, the three major families of stainless steel behave differently to each other, carbon steels, aluminium and copper alloys because, as shown in the bar chart, the coefficient of thermal expansion and conductivity - and their ratio - varies.  

K-TIG: A Quantum Leap for Welding

K-TIG: A Quantum Leap for Welding

Innovation Design Set to Transform the Industry

For the past six decades, the welding process has only been tweaked and modified, but one Adelaide company has developed a new process set to save millions of dollars and forever change the way welds are performed.

Guidelines to Using AS/NZS 1554.6 for Welding Stainless Steel

Guidelines to Using AS/NZS 1554.6 for Welding Stainless Steel

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.
