Question 1

How much better are Super Duplex Steel Shims than regular Duplex shims?

Accepted Answer

Super Duplex has much more strength and twice as much resistance to corrosion than standard Duplex steel. This is accomplished with the addition of additional chromium and molybdenum to the alloy. It is only used in the highest pressure and temperature applications.

Question 2

Where are Super Duplex Steel Shims necessary for reliable operation?

Accepted Answer

They are also vital in the offshore oil and gas company particularly in equipment of deep sea and high pressure riser systems. They are also needed in highly corrosive conditions in pulp and paper mills as well as harsh heat exchangers.

Question 3

Is there a risk of Super Duplex Steel Shims becoming brittle during use?

Accepted Answer

Yes the material may tend to be brittle due to prolonged exposure to high temperatures (above 300 degrees Celsius) and this is a well known problem known as thermal embrittlement. Fabricators need to exercise a lot of caution with the welding and thermal processes so that the shims are not hardened.
