The material shall conform to mechanical property requirements for tensile strength, yield strength, and elongation. Incoloy HT has further modifications to the combined titanium and aluminum levels. It is used in high temperature services.

ASTM B408 Round Bar | Incoloy 800 Round Bar Suppliers

Excellent cold forming characteristics typically associated with the nickel-chromium alloys are exhibited with HT. ASTM B Round Bars are used for process piping, heat exchangers, heating-element sheathing, carburizing equipment, and nuclear steam-generator tubing etc.

For information on machining, click here. Incoloy HT can be welded by the common techniques used on stainless steels.

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 alloy is dual certified and combines the properties of both forms. The material shall conform to mechanical property requirements for tensile strength, yield strength, and elongation. Link to Active This link will always route to the current Active version of the standard. Machining Type Suggested starting rates are: Type C-3 for finishing.

Historical Version s – view previous versions of standard. These rates are for carbide tools, Type C-2 for roughing, drilling and reaming. Test methods chemical analysis, tension test, grain size test shall be performed in accordance to referenced ASTM documents itemized herein.


These Nickel Round Bars are used for Heat exchangers, Pressure vessels, Dampers, Nitric acid catalyst supports, Reformer outlet pigtails and manifold, and more. Offer on Fasteners Sitemap. We offer Round Bars in different sizes, dimensions, specifications and standards as per client requirements.

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

Alloy HT Rods is particularly useful for high-temperature equipment in the petrochemical industry because the alloy doesn’t form the embrittling sigma phase after long time exposure at Degree F Degree C.

These Round bars have various applications in the industry. Please give us a Review.

ASTM B Incoloy Alloy Round Bar Supplier ยท ASTM B UNS N

When cold formed extensively the grain size produces a visibly undulated surface called “orange peel”. The chemical balance allows the alloy to exhibit excellent resistance to carburization, oxidation and nitriding atmospheres.

Incoloy H material can be supplied in random lengths, cut to order or asstm to customer requirements. The H modification was to control carbon 0. Typical applications for the alloy include ethylene pyrolysis, hydrocarbon cracking, cracking furnaces for vinyl chloride, diphenol and acetic acid. The alloy is also used for valves, fittings and other components exposed to corrosive attack from to deg F. The chemical balance allows the nickel steel alloy to exhibit excellent resistance to carburization, oxidation and nitriding atmospheres.

In the solution annealed condition, alloys H and HT have superior creep and stress rupture properties. Incoloy Round Bars have high strength properties, heat treatable, good corrosion resistance, formability and weldability. Incoloy Round Bars is a nickel-chromium alloy bar that awtm supplemental amounts of columbium, iron, molybdenum, aluminum, and titanium. Mechanical Property Requirements Ultimate Tensile, min. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.


Siddhagiri Metals and Tubes Manufacturer: Humble, Texas fax The general corrosion resistance is excellent. Request quote on this grade. This abstract is a brief summary of the referenced standard. Siddhagiri Metals and Tubes Rating: Megamex is b4088 metal supplier for hastelloy, monel, inconel, stainless steel, carbon steel, metal fabrication, nickel alloys, and more. High Performance Alloys stocks and produces Incoloy H in this grade in the following forms: These nickel steel alloys are identical except for the higher level of carbon in alloy H, and the addition asfm up to 1.

The higher strength results from close control of carbon, aluminum and titanium contents in conjunction with a high temp anneal.

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. The values given in parentheses are mathematical conversions to SI units that are provided for asrm only and are not considered standard.

IncoloyH, and HT are nickel-iron-chromium alloys with good strength and excellent resistance to oxidation and carburization in high-temperature exposure. Incoloy Round Bars has excellent cryogenic and heat ranges.
