Applications for stainless steel

Stainless steel’s strength, resistance to corrosion and low maintenance make it the ideal material for a wide range of applications. It also has a long-life cycle and is 100% recyclable.

There are over 150 grades of stainless steel, of which 15 are commonly used in everyday applications. Stainless steel is made in almost every form for use in industrial and domestic settings.


Common Uses of Stainless Steel

Architecture and Construction

Due to its strength, flexibility and resistance to corrosion, stainless steel is now commonly used in modern construction. It is used in the exterior cladding for large high impact buildings and can be seen in the interiors too in the form of handrails, counter tops, backsplashes lifts and more.

Stainless steel is easily welded, has an attractive finish and is low maintenance. Because of this, it is featured prominently in high-profile modern architecture including the Britomart transport hub in Auckland, the Len Lye centre in New Plymouth the Helix Bridge in Singapore, and the One World Trade Centre in New York.

The trend towards sustainable building also favour’s stainless steel, which is often comprised of 90% recycled metal.



Stainless steel is ideal for hygienic environments as it’s easily sterilized and resistant to corrosion. It is used in the construction of surgical and dental instruments, kidney dishes and operating tables, as well as other medical equipment such as cannulas, steam sterilizers and MRI scanners.

Surgical implants use stainless steel, as well as replacement joints such as artificial hips. Stainless steel pins and plates are used to fix broken bones in place.


Energy and Heavy Industries

The chemical, oil and gas industries operate in demanding environments involving high heat and highly toxic substances. Special grades of stainless steel have been developed for use in these industries which feature enhanced resistance to corrosion over a wider range of temperatures. High-grade stainless steel is vital in the construction of storage tanks, valves, pipes, and other components.

Super duplex steel is often used due to its high strength. It can be produced in large sheets which minimizes welding and maximizes structural integrity. Its higher strength also reduces the need for extra structural support and foundations, reducing construction costs.

Stainless steel is essential for offshore oil rigs. Crude oil is extremely corrosive and modern rigs are constructed from high alloyed steel which is tough and lightweight.

Renewable energy technologies including solar, geothermal, hydro and wind power also use stainless steel components which withstand the rigors of highly corrosive sea water environments.


Food and Catering

Stainless steel is used Widley in food preparation as a finish for refrigerators, freezers, countertops and dishwashers. Stainless steel is ideal for food production and storage as it does not affect the flavour of the food. Stainless steel’s corrosion resistance is important as some foods, like orange juice, can be acidic. Stainless steel is easily cleaned which helps keep undesirable germs at bay.


Wine and dairy

Due to its hygienic qualities stainless steel is used widely in wine and Dairy production for wine and milk tanks.
