Causes & Prevention Of Stainless Steel Corrosion

The phrase “because I like it” does not cut it when it comes to choosing styles and materials for architecture structures and interior design elements. When choosing a stainless steel object, whether it be stainless steel balustrades, a pan or even a kettle, above the aesthetical value of the material, other properties should be taken into consideration.


Determine Potential Causes of Damage

Stainless steel is very robust and durable; however, like all other materials, there are various factors that could potentially cause corrosion, namely:

  • Situation. Stainless steel inside a building is protected from elements, such as rain, that would normally affect it if it were outdoors.
  • Exposure to salt air. Areas near the coast have a higher level of salt than inland areas. The exposure to salt air may damage the material.
  • Weather conditions. High levels of humidity and high temperatures may cause the material to corrode after a while.
  • Environment. Pollution, usually more dense in industrial, urban and rural areas, can possibly cause the material to corrode.

The above factors need to be taken into consideration when determining the ideal grade of stainless steel for a project.


Apply Surface Finish

Once you have chosen a suitable grade of stainless steel for your item or project, you can still improve the durability and aesthetic appeal of the material. For exterior purposes, corrosion control is very important. Rough stainless steel surfaces can succumb to more corrosion, while smoother surfaces do not accumulate as many corrosive elements.

To avoid corrosion all together, you can apply a suitable surface finish, PVD coating (Physical Vapour Deposition). The coating is available in a range of colours and surface finishes and is ideal for any stainless steel application.
