Pipework fabrication showing the weld that indicates it was produced from flat plate .
to aid routine maintenance . Connectors , reducers and other sections of process pipework were also produced in this grade , mostly fabricated from plate .” “ Although weldability has historically been seen as a limiting factor in the uptake of super duplex stainless steels , those fabricators who are routinely processing such grades find them no more complicated than many other metals . Just a case of using the correct consumables and following qualified weld procedures . Our customer Metalcraft Inc continues to produce a wide range of components in
Ferralium 255 , with positive feedback from the end user .” “ As well as projects in North America , we are routinely providing metal to end users across North Africa and Europe for the fabrication of very similar components . Off-gas impeller fans are also another common application we supply , for fertiliser production and mining applications . The challenges remain the same , with particulate matter , high throughputs and the presence of corrosive wet fume combining .” “ Not all applications are fabricated from plate , for instance smaller agitators may use a solid bar as the shaft , with plate only used for the blades themselves . We are also supplying Ferralium 255 bar , sometimes with additional heat treatment processing , machining and inspection , to produce pump and valve components for new facilities .” With fertiliser production expected to continue growing year-on-year , the ongoing use of this family of super duplex alloys is almost certain to continue – that combination of their high strength , excellent corrosion resistance , cost effectiveness and ready availability proving a winning combination .
