New project on 13%Cr materials attracts interest
The 13%Cr weldable martensitic stainless steels offer the potential to replace duplex stainless steels in some oil and gas service with a material cost saving of about 50%. In December 1998, TWI held the inaugural meeting of the follow-on proposal GP/MAT1151 Optimising the properties of weldments in weldable martensitic and super martensitic stainless steels. This received tremendous support from industry with 15 companies in attendance and a further eight expressing interest but unable to attend. Five organisations have already committed to supporting this project: Chevron Research & Technology, ESAB, Lincoln electric company, NKK Corporation and RCO Exploration & Production. It is anticipated that Shell International and Total Oil Marine will join imminently and other potential sponsors are expected to join soon. If you wish to participate, early contact with TWI is recommended.

Joining titanium - from design to service
A one-day seminar will be held on Wednesday 26 May at Great Abington covering ways to increase quality and decrease production costs of titanium fabrications. Presentations by experts and practical demonstrations will provide valuable information on the latest joining, NDE and performance developments. More details on this event are available from the Meetings Section. E-mail: firstname.lastname@example.org
