Paraffin corrosion of 17-7PH

Paraffin corrosion of 17-7PH

Paraffin corrosion of 17-7PH

(OP)
Does anyone have any information on the corrosion of 17-7PH by a hydrocarbon fluid called isoparaffins, specifically ISOPAR H made by Exxon?  Is there any reason to assume the hydrocarbon fluid would be corrosive?  I've been unable to find any information on this.  The properties of the material don't seem to indicate that it would be a problem.

Thanks.

Paul

RE: Paraffin corrosion of 17-7PH

This is a highly pure hydrocarbon and shouldn't corrode "as is". However, when oxidized, as with other paraffinic hydrocarbons, break down organic acids, aldehydes, etc., may form. At the right temperatures these acids may attack st. steels. SS 316 and SS 317 are more resistant probably because of their Molybdenum content.
