Product Overview
Incoloy 800, 800H, and 800HT are nickel-iron-chromium alloys with excellent strength and superior resistance to oxidation and carburization in high-temperature environments. These nickel steel alloys are similar, with alloy 800H featuring higher carbon content and alloy 800HT containing up to 1.20% aluminum and titanium for enhanced high-temperature performance.
Incoloy 800HT is dual certified (800H/HT) and combines the properties of both forms, making it ideal for high-temperature structural applications. The nickel content provides exceptional resistance to chloride stress-corrosion cracking and prevents embrittlement from sigma phase precipitation.
Available Forms
- Sheet
- Plate
- Bar
- Pipe & Tube (welded & seamless)
- Fittings (flanges, slip-ons, blinds, weld-necks, lapjoints, long welding necks, socket welds, elbows, tees, stub-ends, returns, caps, crosses, reducers, and pipe nipples)
- Wire
