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.

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

Running Water

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

Welding Dissimilar Metals

Welding Dissimilar Metals

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 in Western Australia Subsea Applications

Stainless Steel in Western Australia Subsea Applications

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.

Star Light, Star Bright

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.

The holes match the

General Corrosion Resistance

General Corrosion Resistance
The normal state for stainless

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

Riverwalk Reborn

Riverwalk Reborn

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.

200 series stainless steels - high manganese (CrMn)

200 series stainless steels - high manganese (CrMn)

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
