Choose casting PMI methods around the elements that matter. Review carbon limits, surface preparation, traceability and the scope of XRF versus OES.

Separate stainless casting chemistry from ferrite assessment. Define test locations, material condition, reporting units and acceptance evidence.

Marine service describes a wide range of conditions, from occasional salt spray to continuous immersion. Marine investment castings therefore need a more precise requirement than a general marine-grade label. Material, geometry and surface condition should be reviewed together for the intended installation.
