SUMMARY:NEIMME Lecture: Corrosion - Super Duplex Stainless Steel in Seawater
DESCRIPTION:This talk covers corrosion of stainless steels in seawater\, what goes wrong\, importance of welding\, and avoiding poor quality materials. \nThe talk addresses all the forms of corrosion that can affect stainless steels in seawater (crevice corrosion\, erosion corrosion\, cavitation\, MIC and HISC) \, and why you need super duplex for most applications. This includes some examples of what can go wrong if you pick the wrong alloy. The talk will also discuss welding duplex stainless steels and how to ensure that welds are of good quality with adequate corrosion resistance. We still see failures due to poor quality welding. Finally there have been failures of duplex stainless steels\, particularly super duplex\, due to poor quality\, and the talk will discuss how to avoid poor quality material for a lot less than the cost of a major failure. \nDr Roger Francis has been a corrosion engineer for over 50 years. He has wide experience in the fields of marine corrosion\, desalination\, sour oil and gas corrosion\, mineral processing\, and the chemical and process industries. He has published over 100 technical papers in all these areas\, particularly on copper alloys and duplex stainless steels. He has written seven books on various aspects of corrosion and has jointly edited three others. The most recent was on corrosion in desalination plants. The author has served as chair of NACE Europe\, two terms as the NACE European Area director and also as chair of NACE STG 32 (Oil and Gas; metals). He was made a NACE Fellow in 2005 for his work in marine corrosion. In 2014 he received the T J Hull Award for his work in publications. In 2023 He was given the Paul McIntyre Award by ICORR in the UK for his work on corrosion standards and in educating young engineers. In 2012 he set up his own corrosion consultancy business\, RFMaterials. \n17:30-18:00 – Tea and Coffee\n18:00-18:50 – Lecture Starts\n18:50 to 19:00 – Q & A \nNEIMME is the Royal Chartered membership organisation for Engineering\, Science and Technology in the North.\nFor more information about our events and the benefits of NEIMME membership see: https://mininginstitute.org.uk/membership/\nFor information on IOM3 membership see: https://www.iom3.org/
