Dear Sir's, I have a equipment in alloy steel (9% Ni) to use in cryogenic temperatures. Can I hydrotest the equipment with seawater without any corrosion problems? Note: Weld Filler material it's a Ni alloy steel. Many thanks in advance. Luis

Dear Luis, The purpose of using 9% Ni steel is enhanced low temperature impact toughness. But I believe this catagory of steel does not have much ability to resist sea water corrosion and susceptible to form pittings if left over. Thus I will recommend not to use sea water with usual high chlorides if at all possible . otherwise >Dear Sir's, regards

Luis For the limited purpose of hydro test - temporary testing time with sea water may not affect the vessel /welds - if after hydro test you are able to thoroughly dry and inspect hope this helps C.V.Srinivasan Nishi Engineers Pvt Ltd India E-mail: nishi@vsnl.com >Dear Sir's, >I have a equipment in alloy steel (9% Ni) to use in >cryogenic temperatures. >Can I hydrotest the equipment with seawater without any >corrosion problems? > >Note: Weld Filler material it's a Ni alloy steel. >Many thanks in advance. >Luis
