When titanium's corrosion envelope is exceeded—by high temperatures, strong reducing acids, or extreme concentrations—nickel alloys take over. This guide covers the most-requested nickel alloy grades, their service envelopes, and how to source plate, tube, rod and wire from one stock-holding supplier.
| Grade | Family | Service Environment | Key Properties |
|---|---|---|---|
| Ni200 / N6 | Pure nickel | Caustic soda, food processing | Excellent ductility, good thermal conductivity |
| Ni201 | Low-carbon pure nickel | High-temp caustic service | Lower carbon for high-temperature stability |
| Monel 400 | Ni-Cu alloy | Seawater, hydrofluoric acid, alkaline solutions | Excellent seawater corrosion resistance |
| Inconel 600 | Ni-Cr alloy | High temp oxidation, carburizing | Good strength to 1093°C |
| Inconel 625 | Ni-Cr-Mo alloy | Seawater, acid, high strength | High strength + excellent corrosion resistance |
| Incoloy 800/825 | Ni-Fe-Cr alloy | Sulfuric acid, phosphoric acid, high temp | Good resistance to sensitization |
| Hastelloy C276 | Ni-Mo-Cr alloy | Strong oxidizers, wet chlorine, bleach | Outstanding in aggressive chemical service |
| Hastelloy C22 | Ni-Cr-Mo-W alloy | Broad chemical resistance | Improved versatility over C276 |
Stock: ~30 tons across all grades and forms.
Because we stock both titanium and nickel alloys, a project that requires Gr2 titanium tube for the condenser and Hastelloy C276 plate for the reactor shell ships on one set of documents, one packing list, one shipment.
Tell us:grade × form × size × quantity × service medium
Example:Hastelloy C276 plate, 10 mm × 1500 × 3000 mm, 2 pcs, for chlorine dioxide service
We recommend the right grade if you provide the medium, temperature and pressure.
