VDM® Alloy 800 HP is an austenitic nickel-iron-chromium alloy with increased content of (Al + Ti), compared to VDM® Alloy 800 H. VDM® Alloy 800 H is an austenitic, heat resistant iron-nickel-chromium alloy with controlled levels of carbon, aluminum and titanium.
VDM® Alloy 800 HP (1.4959/N08811) is chracterized by:
A special solution annealing results in a grain sizes ≥ 90 μm (ASTM No. 4) and highest creep rupture strength above 700 °C (1,290 °F) due to titanium carbide precipitation. Below 700 °C (1,290 °F), γ' precipitates combined with a loss of ductility.
VDM® Alloy 800 HP has a wide range of applications in areas of elevated temperatures in furnace construction, in the chemical industry, in environmental protection equipment, in the automotive industry and in power plants. Typical applications include furnace muffles, containers, bins, holders in various heat treatment plants and burner components.
Because of their resistance to carburization and nitriding, the alloys are furthermore used in the areas of:
