316L Nace specification
316L Nace specification
(OP)
Hi guys,
I'm writting a specification in order to get some 316L material for NACE application.
In the norm MR0175, it is specified that martensite content of this grade has to be kept under a certain amount. I'm trying to fix the value, but I'm not finding any information about this.
Does anyone know:
- The level of Martensite generally observed in such grade (wrought alloy)
- Some literature about the influence of this phase in the corrosion resistance of the 316L
- A reasonnable limit to fix in order to procure some material (I know that the less is the better, but I want it to be realistic and I don't want to look for a chimere...)
Many thanks for your help!

Type 316L can contain martensite only if it's severely deformed. In NACE / ISO is stated that the SS shall be free of cold work intended to increase hte mechanical properties.
I think that if you follow all the requirements of the standard, heat treatment, hardness.. you'll have no problem of martensite formation.
In the norm is written that a limit on martentisite shloud be considered so is not a strict requirements.
