We have Stainless steel piping
Application
Offshore: Oil and gas.
1) Some lines are subjecte to 85 Deg C
2) Some line are subjected to 133 Deg C and
3) Some line are subjected to 204 Deg C
4) Some line are subjected to 285 Deg C
We we peocure the material they are bright and after we fabricate them we Pickle and passivate them
My Question is
A) At what temperature the SS 316L will start getting the heat tint
B) If in any case, the heat tint is going to occur at "X" deg C and if we the end use is going to be at higher temperature, why take the trouble to Pickle at all?
