For the advanced and aerospace manufacturing, material selection is not a place to cut corners. 304H Stainless (UNS S30409) delivers the performance that Charleston’s manufacturing and marine operators depend on, and P.A. Inc. keeps it on the shelf — ready for fast delivery across South Carolina.
What makes 304H Stainless the right specification is straightforward: higher creep and rupture strength than standard 304 above 1000°f (540°c) and good oxidation resistance in intermittent and continuous high-temperature service. For Charleston operators, that translates into longer service life, fewer unplanned outages, and predictable behavior during the thermal and chemical cycling their processes put material through.
Our Charleston customers put 304H Stainless to work across the demanding end of process service: high-temperature refinery and petrochemical piping, superheater and reheater tubing, boiler and pressure-vessel components, and furnace and process headers. Because P.A. Inc. fabricates locally in Houston, we can turn butt-weld fittings, flanges, and custom spools to the exact schedule and end-prep a Charleston turnaround crew needs — and deliver to North Charleston, Goose Creek, and Hanahan and the surrounding region without the freight time of pulling material from out of state.
For Charleston buyers working to tight ASME and API documentation standards, paperwork matters as much as metal. That’s why every order of 304H Stainless ships with complete, original Mill Test Reports and full heat traceability — backed by a service center that answers the phone around the clock.
