Incoloy 800 H / HT (UNS N08811) Fe base, Ni 32, Cr 21, Mn 1.5 Description

Incoloy Round Bars is a nickel-chromium alloy bar that contains supplemental amounts of columbium, iron, molybdenum, aluminum, and titanium. When cold formed extensively the grain size produces a visibly undulated surface called “orange peel”.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. The general corrosion resistance is excellent. It is used in high temperature services. Power plants use them for super-heater and re-heater tubing.

Historical Version s – view previous versions of standard. Excellent cold forming characteristics typically associated with the nickel-chromium alloys are exhibited with HT. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application.

Please give us a Review. These rates are for carbide tools, Type C-2 for roughing, drilling and reaming. The chemical balance allows the alloy to exhibit excellent resistance to carburization, oxidation and nitriding atmospheres.


Humble, Texas fax Incoloy Round Bars have high strength properties, heat treatable, good corrosion resistance, formability and weldability. The material shall conform to mechanical property requirements for tensile strength, yield strength, and elongation. Incoloy H material can be supplied in random lengths, cut to order or machined to customer requirements. All the products are manufactured asmt per international quality and safety standards. Test methods chemical analysis, tension test, grain size test shall be performed in accordance to referenced ASTM documents itemized herein.

Incoloy was the first of b40 alloys and it was slightly modified into Incoloy H. Machining Type Suggested starting rates are: The n408 is dual certified and combines the properties of both forms. In the solution annealed condition, alloys H and HT have superior creep and stress rupture properties.

asstm The H modification was to control carbon 0. Incoloy Round Bars is commonly used for valves, fasteners, tubing materials and mandrels. Machining includes drilling, threading, milling, CNC shapes, turning, tapping, flanges and others. The material shall conform to mechanical property requirements for tensile strength, yield strength, and elongation.

ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date. Siddhagiri Metals and Tubes Rating: Astk nickel content makes the alloys highly resistant to both chloride stress-corrosion cracking and to embrittlement from precipitation of sigma phase. Megamex is a metal supplier for hastelloy, monel, inconel, stainless steel, carbon steel, metal fabrication, nickel alloys, and more.

Incoloy HT has further modifications to the combined titanium and asstm levels. 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.


This modification was to control carbon.

It is in the form ast, Hot-Worked and Cold-Worked. The higher strength results from close control of carbon, aluminum and titanium contents in conjunction with a high temp anneal. Incoloy H has further modifications to the combined titanium and aluminum levels 0. ASTM B Round Bars are used for process piping, heat exchangers, heating-element sheathing, carburizing equipment, and nuclear steam-generator tubing etc.

The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. These Nickel Round Bars are used for Heat exchangers, Pressure vessels, Dampers, Nitric acid catalyst supports, Reformer outlet pigtails and manifold, and more. The material shall be subjected to heat treatment, and its composition shall conform to the chemical requirements for nickel, chromium, iron, manganese, carbon, copper, silicon, sulfur, aluminum, titanium, columbium, molybdenum, niobium, tantalum, phosphorus, tungsten, cobalt, nitrogen, and boron.

The chemical balance allows the nickel steel alloy to exhibit excellent resistance to carburization, oxidation and nitriding atmospheres.

We offer Round Bars in different b480, dimensions, specifications and standards as per client requirements. Looking for some more information?
