The Chairman (Robin Oakley) opened the meeting.  


1.1    ‘High Strength Alloys in the Presence of CP Subsea and the Requirements for Preventing Hydrogen Cracking’, Charlie Barraclough, Commtech Associates

1.2    ‘Microbially Influenced Corrosion in both Oil Lubricated and Sea Water Lubricated Stern Tube Systems’, Graham Hill, ECHA Microbiology


2.   OPEN FORUM    

2.1        Andy Mather (Rolls Royce) asked whether anyone had experience with martensitic stainless steels (particularly 12% Cr) and the influence of hardness/tempering temperature upon EAC (specifically hydrogen assisted cracking) susceptibility in marine environments.  In addition any experience of EAC failures of these types of material due to excessive hardness. 

Roger Francis (RF Materials) said he had had experience of 17/4PH bolts cracking when operating at a temperature of 74°C and splashed with seawater.  Tests were carried out on a number of heat treated conditions of the bolts and it was found that the heat treatment which gave  lowest strength (0.2% Proof Strength 725MPa) was the one which was able to survive this environment.  It is a fact that strength has to be sacrificed if resistance to SCC is required.  It was recommended that reference be made to Sedrick’s book on stainless steel corrosion (A.J.Sedricks  ‘The Corrosion Stainless Steel Steels’, J Wiley 1979) for details of the performance of different stainless steels and the particular conditions when stress corrosion occurs.  If stress corrosion cracking is known to be a potential problem for a stainless steel in a particular environment, then fracture mechanics testing would be recommended to find out the threshold stress which needs to be considered.

2.2    The Chairman announced the recent death of Brian Angel (MoD), who had been a member of the Marine Corrosion Club (as it was then) in the early days.  He had been based at Holton Heath, and many of the MCF would have known him, including for his book on corrosion behaviour, materials & marine environments.

3.         MCF NEWS
