Duplex stainless steels are being increasingly used as structural materials in chemical and petrochemical applications, in power plants, etc. This is mainly due to their high resistance to localised corrosion as well as to their high strength and toughness.
Types Of Duplex Steel:
Duplex Steel Pipe
The basic concept of duplex stainless steel is to produce a chemical composition that creates an equal mix of austenite and ferrite. This balance of phases provides the following: Higher strength – The range of 0.2% PS for the current duplex grades is from 400 – 550 MPa.

Duplex Steel Tube
The Duplex Tube Fittings are renowned for their dual microstructure phase. The microstructure of DSS Bulkhead Tube Fittings is an equivalent 50 % each austenite and ferrite. Therefore the Duplex Steel Instrument Tube Fittings share characteristics of both steel classes.

Duplex Steel Plate
Duplex steel plates are flat, broad sheets of material that find applications in structural and industrial projects. Their high strength and corrosion resistance make them valuable for constructing pressure vessels, storage tanks, and various structural components.
