Product Description

Strong Corrosion Resistance UNS S31803 /2205 Duplex Steel Tube ASTM A790 For Chemical Industry

 

 

Duplex stainless steels have a combination of two phases, ferrite and austenite in approximately equal measure. This allows them to benefit from the advantages of both austenitic and ferritic stainless steels, leading to increased strength, improved weldability, higher toughness and resistance to several types of corrosion. Commercially, they are also cheaper than austenitic stainless steels due to their lower nickel content.

Super duplex stainless such as duplex is a mixed microstructure of austenite and ferrite which has improved strength over ferritic and austenitic steel grades . The main difference is super duplex has a higher molybdenum and chromium content which gives the material greater corrosion resistance . Super duplex has the same benefits as its counterpart - it has lower production costs when compared with similar ferritic and austenitic grades and due to the materials increased tensile and yield strength , in many cases this gives the purchaser the welcomed option of purchasing smaller thicknesses without the need to compromise on quality and performance .
