Delta Fastener Corp. can provide a wide variety of Incoloy fasteners including; incoloy nuts, incoloy bolts, sockets, washers and more in Incoloy fasteners. If we do not have your incoloy fasteners in stock (Inch or Metric) we can have these manufactured to your specification.
A nickel-iron-chromium alloy with good strength and excellent resistance to oxidation and carburization in high-temperature atmospheres. It also resists corrosion by many aqueous environments. The alloy maintains a stable, austenitic structure during prolonged exposure to high temperatures. Used for process piping, heat exchangers, carburizing equipment, heating-element sheathing, and nuclear steam-generator tubing. Standard product forms are round, flats, forging stock, pipe, tube, plate, sheet, strip, and wire.
