ASTM B163 B407 ASME SB163 SB407 N08800 EN 10216-5 1.4558 Nickel Alloy Seamless Tubes Pipes Incoloy 800 Seamless Tubing designed to resist Oxidation and Carburization. The general corrosion resistance is excellent. Incoloy alloy 800 is a widely used material of construction for equipment that must have high strength and resist oxidation, carburization, and other harmful effects of high temperature exposure. (For high temperature applications requiring optimum creep and rupture properties, Incoloy alloys 800H and 800HT are used).

The chromium in the alloy imparts resistance to oxidation and corrosion. The high percentage of nickel maintains an austenitic structure so that the alloy is ductile. the nickel content also contributes resistance to scaling, general corrosion, and stress-corrosion cracking. The iron content provides resistance to internal oxidation.

ASTM B163 B407 ASME SB163 SB407 N08800 Nickel Alloy Seamless Tubes Pipes Incoloy 800 Seamless Tubing is used in a variety of applications involving exposure to corrosive environments and high temperatures. It is used for heat-treating equipment such as baskets, trays and fixtures. In chemical and petrochemical processing the alloy is used for heat exchanger and other piping systems in nitric acid media especially where resistance to chloride stress-corrosion cracking is required. In nuclear power plants, it is used for steam-generator tubing. The alloy is often used in domestic appliances for sheathing of electric heating elements. In the production of paper pulp, digester liquid heaters are often made of alloy 800. In petroleum processing , the alloy is used for heat exchanger that air-cool the process stream.

A Ni-Cr-Fe alloy that resists high temperature oxidation. This alloy is a first choice for an upgrade from the 300 series stainless steel when improved performance or strength at temperature is required. For higher ASME Boiler and Pressure Code design values, consider Alloy 800HT.
