Blue coloration on stainless steel when subjected to heat [India] 

March 24, 2006

I wish to know what temperatures stainless steel pipe of grade AISI 316L has reached if blue spots are observed on pipe when it is subjected to heat in limited air atmosphere for a duration of 75 minutes.

This is one of the weirdest thermometers I've ever heard of, Abhijeet :-)

Please provide the background and why you want to know. Thanks and good luck!
