As we talked in the last article about the corrosion of stainless steel and what causes it, today we’re going to talk about the types of corrosion which might happen.
As I mentioned in the previous article, it’s important to take into account several points when we talk about corrosion and see what might cause it.
Today, I’m going to introduce some types of corrosion which might affect the stainless steel.
- Pitting corrosion
This type of corrosion is local and it is a result of exposure to a specific environment. I know that all this might sound rocket-science but it’s not like that. Things are quite simple.
So, what does pitting corrosion really mean? Pitting corrosion is actually creation of the small holes in the metal.
Yes. Quite simple, right?
Usually, these small holes appear when the stainless steel is exposed to some kind of aggresive chemical substances.
- Crevice corrosion
This type of corrosion sounds rocket science too. But don’t worry it’s not. The only thing that’s rocket science is the name.
So, first thing first. What’s a crevice? A crevice can be defined as a confined space, where the access of the working fluid is limited. It sounds science-fiction, but if you take a look at the picture you’ll notice that basically this crevice means a small crack or a gap in the surface.
It might sound scarry and maybe that even the pictures look scary, but you don’t have to worry too much about it. This corrosion usually happens after a long period of time or when the products have been exposed to a harsh environment, with powerful factors or substances which can cause the corrosion.
However, I can recommend to take a look at the products available here: http://speedfab.com/. Speedfab’s products have a guaranteed quality and their stainless steel handrail, won’t cause you any problems regarding the corrosion.
