Duplex Usage in Desalination Plants

Introduction: Desalination Plants are known to be very severe environments due to the high chloride, high temperature conditionsi. In the past, austenitic stainless steels in the ASTM 300 series tended to be the material of choice in desalination plants. In cases in which even higher corrosion resistance has been needed, the typical material solution has  Continue Reading →

The History of Duplex Stainless Steel

Early Duplex Development: Duplex stainless steels, which combine many of the beneficial properties of ferritic and austenitic steels, were originally developed in the early 1930′s. The initial duplex grades provided good performance characteristics, but had limitations in the as-welded condition. The metallurgical processes at that time were not suitable for producing grades with the right  Continue Reading →
