The nickel content makes the alloys highly resistant to both chloride stress-corrosion cracking and to embrittlement from precipitation of sigma phase.

High Performance Alloys stocks and produces Incoloy H in this grade in the following forms: The material shall be subjected to heat treatment, and its composition shall xstm 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 material shall conform aastm mechanical property requirements for tensile strength, yield strength, and elongation. Incoloy Round Bars have high strength properties, heat treatable, good corrosion resistance, formability and weldability. Incoloy HT can be welded by the common techniques used on stainless steels. It is in the form of Hot-Worked and Cold-Worked. For information on machining, click here. The H modification was to control carbon 0. The alloy is also used for valves, fittings and asmt components exposed to corrosive attack from to deg F.

Test methods chemical analysis, tension test, grain size test shall be performed in accordance to referenced ASTM documents itemized herein.


The material shall conform to mechanical property bb408 for tensile strength, yield strength, and elongation. Astn chemical balance allows the nickel steel alloy to exhibit excellent resistance to carburization, oxidation and nitriding atmospheres.

When cold formed extensively the grain size produces a visibly undulated surface called “orange peel”. Please give us a Review. Offer on Fasteners Sitemap.

Incoloy H material can be supplied in random lengths, cut to order or machined to customer requirements.

Looking for some more information? The higher strength results from close control of carbon, aluminum and titanium contents in conjunction with a high temp anneal. Common uses of Incoloy include deployment in gas turbines, subservice safety valves, aircraft engines, thrust reversers, and industrial fasteners.

Incoloy Round Bars is a nickel-chromium alloy bar that contains supplemental amounts of columbium, iron, molybdenum, aluminum, and titanium.

The alloy is dual certified and combines the properties of both forms. Excellent cold forming characteristics typically associated with the nickel-chromium alloys are exhibited with HT. Incoloy H has further modifications to the combined aatm and aluminum levels 0. These Nickel Round Bars are used for Heat exchangers, Pressure vessels, Ast, Nitric acid catalyst supports, Reformer outlet pigtails and manifold, and more.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. These rates are for carbide tools, Type C-2 for roughing, drilling and reaming.


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

The general corrosion resistance is excellent. Machining Type Suggested starting rates are: IncoloyH, and HT are nickel-iron-chromium alloys with good strength and excellent resistance to oxidation and carburization in high-temperature exposure.

Type C-3 for finishing. Megamex is a metal supplier for hastelloy, monel, inconel, stainless steel, carbon steel, metal fabrication, nickel alloys, and more.

ASTM B408 Round Bar | Incoloy 800 Round Bar Suppliers

Incoloy was the first of these alloys and it was slightly modified into Incoloy H. The chemical balance allows the alloy to exhibit excellent resistance to carburization, oxidation and nitriding atmospheres. Excellent cold forming characteristics typically associated with the nickel-chromium alloys are exhibited with HT. Incoloy Round Bars is commonly used for valves, fasteners, tubing materials and mandrels. Siddhagiri Metals and Tubes Manufacturer: Machining includes drilling, threading, milling, CNC shapes, turning, tapping, flanges and others.

This abstract is a brief summary of the referenced standard. Incoloy HT has further modifications to the combined titanium and aluminum levels.
