ASTM B407 UNS N08811 DIN 1.4959 ( INCOLOY 800HT ) SEAMLESS PIPE NICKEL ALLOY PIPE
Each specimen, in this case, Incoloy 800HT Tube is to be subjected to either a hydrostatic test or a non-destructive eddy current test. Tests on the ASTM SB 407 UNS N08811 Inconel 800HT Tubing is performed in order to not only determine the allowable fibre stress but also to detect any significant discontinuities. Generally, discontinuities such as a drilled hole or a transverse tangential notch could occur on the Incoloy Alloy 800HT Seamless Tube. The cold-drawn DIN 1.4959 Tube, according to the ASTM B407 specification needs to be commercially straight.

More information about Incoloy 800, Incoloy 800H, Incoloy 800HT
Incoloy 800, Incoloy 800H, Incoloy 800HT, also named as Alloy 800, Alloy 800H, Inconel 800, Alloy 800HT are nickel-iron-chromium alloys with good strength and excellent resistance to oxidation and carburization in high-temperature exposure. These nickel steel alloys are identical except for the higher level of carbon in alloy 800H, and the addition of up to 1.20 percent aluminum and titanium in alloy 800HT. Incoloy 800 was the first of these alloys and it was slightly modified into Incoloy 800H. This modification was to control carbon (.05-.10%) and grain size to optimize stress rupture properties. Incoloy 800HT has further modifications to the combined titanium and aluminum levels (.85-1.20%) to ensure optimum high temperature properties. The nickel alloy is dual certified (800H/HT) and combines the properties of both forms. Incoloy 800H/HT alloy was intended for high temperature structural applications. The nickel content makes the alloys highly resistant to both chloride stress-corrosion cracking and to embrittlement from precipitation of sigma phase. The general corrosion resistance is excellent. In the solution annealed condition, alloys 800H and 800HT have superior creep and stress rupture properties.
Incoloy 800 is primarily used in applications with temperatures up to 1100° F, where alloys 800H and 800HT are normally used in temperatures above 1100° F where resistance to creep and rupture is required. The chemical balance allows the nickel steel alloy to exhibit excellent resistance to carburization, oxidation and nitriding atmospheres. Incoloy 800HT will not become embrittled even after long periods of usage in the 1200-1600° F range where many stainless steels become brittle. Excellent cold forming characteristics typically associated with the nickel-chromium alloys are exhibited with 800HT. When cold formed extensively the grain size produces a visibly undulated surface called “orange peel”. Incoloy 800HT can be welded by the common techniques used on stainless steels.
The characteristics of Incoloy 800, Incoloy 800H and Incoloy 800HT

- Valves, fittings and other components exposed to corrosive attack from 1100-1800° F
- Industrial furnaces
- Heat-treating equipment
- Chemical and petrochemical processing
- Super-heater and re-heaters in power plants
- Pressure vessels
- Heat exchangers
Alloys 800H/HT are used in a variety of applications involving exposure to corrosive environments and high temperatures such as heat treating equipment, chemical and petrochemical processing, nuclear power plants and the paper pulp industry. Heat-treating equipment such as baskets, trays, and fixtures employ Incoloy 800H/HT. Chemical and petrochemical processing industries use the alloys for heat exchangers and other piping systems in nitric acid media especially where resistance to chloride stress-corrosion cracking is required. Power plants use them for super-heater and re-heater tubing.
