APPLICATION OF STAINLESS STEEL

The reason why stainless steel is so appealing to use for many of its uses is because of its resistance to corrosion as well as its oxidation in low and high temperatures thanks to its high levels of chromium. These and other features are what separate stainless steel from other mild steels. Even though stainless steel square tubing may not be the cheapest option available on the market, there are many benefits to using it.
Aside from offering excellent resistance to corrosion, which further makes it incredibly useful in thin wall piping, this tubing also offers low fluid friction properties and are also incredibly easy to maintain. This contributes tomaking stainless steel square tubing incredibly cost effective. This type of tubing has also been used in the construction of long-lasting and safe structures such as factories.
These tubes have been made to withstand many different environments with many varying temperatures. Other types of stainless steel tubing and its uses include:

  • Austenitic: This type of tubing is non-magnetic, ductile and is excellent for welding. It is used chiefly to make kitchen wares, containers and large scale piping with.
  • Ferritic: This type of stainless steel square tubing shares a lot of common traits with austenitic, but offers a lot better resistance to corrosion. It is used in the manufacture of indoor equipment such as a washing machine.
  • Austenitic-Ferritic and Duplex tubing: This tubing is both ductile and strong, and its main use is found in industries such as the shipbuilding sector and paper pulp industries.
  • Heat resistant tubes: These are used for steaming where temperatures can reach very high levels. They are also entirely resistant to heat and are used in boilers.

These are only a few of the many types of stainless steel square tubing products that keep many of South Africa’s most important industries moving. We are the proud stockists and suppliers of a wide range of aluminium alloys in sheets, coil, tread plates and plates. We also stock a wide variety of Duplex, Austenitic and Ferritic grades stainless steel coil, sheets and plates. All of our extensive range of products are sourced form the best quality local and international mills.
