Understanding the different grades of steel

The construction industry is one that requires a certain amount of specific components, with steel cladding and fixings being amongst them. With special coatings for extra protection and high-grade materials that ensure that their performance is nothing short of spectacular, our products are just perfect for various jobs. With numerous models on offer, you are sure to find what it is that you’re looking for here.

Stainless steel is the main substance used in the manufacture of fixings and is also very common for cladding. Whilst multiple grades of steel are utilised, two primary ones are that of A2 and A4. To understand which one best suits your particular needs, possessing knowledge on their characteristics is paramount.

A2 grade steel is non-magnetic and is austenitic, with its chromium build offering excellent oxidation and corrosion resistance. It is immune to the majority of organic chemicals, dyestuffs, sterilising solutions and foodstuffs. In addition, it can also stand against a plethora of inorganic materials. Because of these aspects, A2 is widely used for sinks, pipelines, stoves, in food processing plants, as steel cladding, and so much more.

Similar to A2, A4 grade steel is austenitic and non-magnetic, and can be used in many of the same situations. The difference between the two however, is that it is more appropriate for marine purposes, often being referred to as Marine Grade stainless steel. With resistance to corrosion, as well as chlorides, and industrial chemicals and solvents, A4 is used extensively within the marine environment.
