[MW:3518] Re: sour service

I think that is a misleading generalisation. There is a lot of excellent information available from the Nickel Institute free of charge, as downloads. All you have to do is search the site for what you want and register - it is entirely free. You can then download vast quantities of good and reliable information about nickel, its alloys, how to weld it, etc. I'd suggest you visit www.nickelinstitute.org
 
Regards,
Owen.

Because Nickel is highly susceptible to stress corrosion cracking even with the presence of  a small amount of sulfide compound.
