Every order of Alloy 803 ships with a complete set of original Mill Test Reports, with traceability not only to the manufacturer but to the origin of the material.
Nominally 32–38% nickel and 25–29% chromium with balance iron and controlled silicon, tuned for carburization resistance.
In-house certified technicians and a qualitative specification-assurance process that is second to none back every shipment leaving our Houston facility.
Bay City sits at the center of the Saginaw Bay’s chemical and specialty-materials plants, and operations here demand piping materials that hold up where ordinary steels fail. Alloy 803 (Incoloy® 803, UNS S35045) was engineered for exactly that duty, and P.A. Inc. stocks it in pipe, fittings, and flanges ready to ship into the Bay City area.
The reason Bay City engineers keep coming back to Alloy 803 comes down to its metallurgy — excellent resistance to high-temperature oxidation and carburization and high creep and stress-rupture strength for long furnace campaigns. In demanding chemical and manufacturing service, those properties are the difference between a component that lasts a campaign and one that fails early.
Our Bay City customers put Alloy 803 to work across the demanding end of process service: ethylene pyrolysis and cracking tubes, steam-methane reformer tubing, petrochemical furnace outlet piping, and high-temperature 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 Bay City turnaround crew needs — and deliver to Essexville, Midland, and Kawkawlin and the surrounding region without the freight time of pulling material from out of state.
Every length of Alloy 803 leaving our facility ships with a full set of original Mill Test Reports, traceable to both the manufacturer and the heat of origin — the documentation Bay City plants operating under ASME and API requirements can’t do without. And with our team answering the phone 24 hours a day, a Bay City turnaround that runs long always has someone to call.
If your Bay City operation needs Alloy 803 Pipe & Fittings — whether it’s a single spool for an emergency repair or a full material package for a planned outage — call P.A. Inc. at 713-570-4900 for pricing, availability, and certified documentation.
