Incoloy 800HT® is nickel-iron-chromium alloy. The alloys’ higher creep-rupture strength is the result of aluminum, carbon, and titanium contents. Incoloy 800HT® is used in chemical and petrochemical processing, in power plants, industrial furnaces, and for heat treating equipment.

Incoloy 800HT® sheet is available in thicknesses ranging from .020 to .156". Incoloy 800HT® strip in coil from is available in lighter gauges up 12" wide. Incoloy 800HT plate is available up 2" thick.

Incoloy 800HT® bar is available in wrought bar up to 8" diameter and larger sizes and shapes may be forged to order.

Incoloy 800HT® seamless pipe is available up to 8" NB. Larger sizes are available in welded construction (100% X-ray) and can also be fabricated to order. Incoloy 800HT® tubing is available up 3" OD. Incoloy 800HT® redrawn tubes and tubing with tight tolerances can be supplied in almost any size no matter how small the size or quantity.

Butt-weld and forged fittings are available or can be manufactured with short lead times.

Available forms are seamless pipe, welded pipe, seamless tube, welded tube, bar, wire, sheet, plate, forgings, pipe fittings and flanges.
