iron oxide analysis
(OP)
hi, all,
we have an un-abnormal corrosion happened on the surface of a SS400 plate, and i would like to ask you guys to give me an instruction on how to analyze the oxide. i will post a few photos of the oxides to you for your reference. the corrosion plate was returned from the customer and what i know is no higher temperature and dry atomsphere condition. thanks in advance.

Do you know the parts history? What has been dripping onto it?
Are there a bunch of these in identical service? Is this the only rusted one?
Are you certain that it was properly passivated before it went into service?

the part has not been used in service, it was just fixed to the customer's equipment. and the time is no longer than 1 month. as for what dripping on the part, sorry, i dont know it and i guess the customer really didn't know. what i will do is as mrfailure said, EDS, chemcial test of the body.
thanks again.
