Super Duplex plate

super duplex plate

A plate that mainly comprises of higher contents of chromium is super duplex plate. It also comprises moderate contents of nickel. This is one of the reasons why they show excellent corrosion resistive properties. Good mechanical properties are shown by the steel plate. Adding to this, you would also use super duplex steel plate to deal with pitting, crevice and stress corrosion cracking based scenarios.

Other than resisting wide range of corrosive environments, there are other benefits that are provided by super duplex perforated sheet, that are listed below:

  • When compared to duplex graded plates, they offer more prominent resistance to corrosion.
  • Because it provides better resistance to fatigue, they exhibit excellent strength.
  • Another advantage is that it does not get easily damages or corroded. Hence, many industries consider this to be an ideal choice, because they are highly durable.
  • Resist stress corrosion cracking.

Other than exhibiting excellent resistance properties; as well as good physical and mechanical characteristics, it is very important for the surface to be shiny and smooth.
To maintain or enrich the surface, below are the two major and most common surface finish methods:

No. 1 finish:

We product this type of finish by the means of hot rolling. After this, we anneal and pickle material. This is done in an acid.
Output of this finish is dull; where we don’t require smooth decorative finish.

No. 2D finishing:

A finish that is produced by the means of cold rolling is no. 2d finish. The finish of the plate is non-reflective and dull, when we suddenly anneal and pickle the plate in acid.
