This month’s Stainless Steel World, the stainless steel industry’s premium publication, includes an extended feature on the history of Ferralium 255.

After more than 50 years of successful service, the article outlines the development history of the very first super duplex stainless steel. It starts with the registration of the original patent, and the metallurgical breakthroughs regarding increased copper content and controlled nitrogen levels to increase pitting corrosion resistance. Initial challenges, such as weldability, are discussed as well as how this new family of alloys has been marketed. Case study examples throughout the years are included to illustrate the article.

Other grades of super duplex stainless steel have subsequently been developed and Langley Alloys now stocks a complete range of these products. Together with our history in their development, we are proud to call ourselves ‘The Home of Super Duplex’.

Langley Alloys would like to thank Joanne McIntyre (Editor in Chief) and the team at KCI Publishing / Stainless Steel World for their efforts in creating this article.
