Where is Inconel 600 in MR0175?
(OP)
We have been using Inconel 600 and 625 in our NACE MR0175 compliant products for many years. In the 1997 version of the spec the relevant sections were 4.1.4.1 and 4.1.5.1. However, upon reviewing the recent 2003 version, section 4.11.1 precludes the use of Inconel 600 because the Mo content is 0. Inconel 625 meets the spec since it has over 2.5% Mo. Am I missing something? Does the spec now exclude Inconel 600?
Thanks for your help.
