15.30 – 16.00 Coffee break
16.00 – 17.30 INTERACTIVE WORKSHOP :
• Appropriate selection and successful uses of duplex stainless steels Hosted by Roger Francis , RF Materials & Joelle Greenwood , Consultant
This workshop will give a brief introduction to the properties of duplex stainless steels and how these can be utilised for a cost effective material selection compared with other alloys . The workshop will also discuss fabricating duplex stainless steels and how to avoid common pitfalls . Some examples will be given where duplex alloys have provided an economic long term option for specific applications , including heat exchangers . Some cases will also show what happens when the limits of use are exceeded .
