DUPLEX BENEFITS

Strength and Cost benefits of Duplex stainless steels

The key benefit of Duplex is its strength.
Because it is so much stronger, the material can be down gauged, resulting in decreased tonnage usage – sometimes up to half the tonnage required for other grades of stainless steel.
NDE has worked on projects over the years where Duplex has reduced tonnage for a project from 600 tons to 400..
This brings cost benefits with frequently lower first-off costs, always much lower life-cycle cost.

Special properties and corrosion-resistance of Duplex stainless steels

The benefits of the special properties of Duplex, particularly its corrosion-resistance, create many opportunities for new specifications and re-engineering.

"Duplex is the world's first engineering grade stainless steel" according to NDE's lead technical consulting chemical engineer Basil Goldswain, with 40 years experiance in stainless steel locally and internationally.

NDE's technical team offers a comprehensive range of expertise to assist customers to make the most of the many benefits of the family of Duplex stainless steels.

DESIGN

We help engineers and professionals to design tanks, vessels and piping systems which eliminate or reduce stainless steel specific corrosion problems such as crevice and pitting corrosion.

SELECTION

The selection of grades of stainless steel suitable for process application is a complex process. We work very closely with the customer and metallurgical laboratories to perform corrosion testing which is meaningful. These tests help the customer to make decisions on materials selection.

   

 

APPLICATION

With many years of experience in the application of stainless steel we are able to help you to ensure a successful project. In many cases we have pointed out the unsuitability of a specific grade of stainless steel in particular applications – and the suitability of an alternative grade - saving vast amounts of
money for our customers.

SUPPLY

NDE's stocks mainly Duplex flat product and piping and also sources specific products locally and globally for customers on request.
