Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. The chemical balance allows the alloy to exhibit excellent resistance to carburization, oxidation and nitriding atmospheres.

Incoloy Round Bars have high strength properties, heat treatable, good corrosion resistance, formability and weldability. The general corrosion resistance is excellent. For information on machining, click here. The H modification was to control carbon 0. Humble, Texas fax It is in the form of Hot-Worked and Cold-Worked. Please give us a Review. The b48 balance allows the nickel steel alloy to exhibit excellent resistance to carburization, oxidation and nitriding atmospheres.

IncoloyH, and HT are nickel-iron-chromium alloys with good strength and excellent resistance to oxidation and carburization in high-temperature exposure. The alloy is dual certified and combines the properties of both forms. Test methods awtm analysis, tension test, grain size test shall be performed in accordance aastm referenced ASTM documents itemized herein.

Mechanical Property Requirements Ultimate Tensile, min. These Round bars have various applications in the industry.

ASTM B408 Round Bar | Incoloy 800 Round Bar Suppliers

Incoloy Round Bars is a nickel-chromium alloy bar that contains supplemental amounts of columbium, iron, molybdenum, aluminum, and titanium. Request quote on this grade. 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. It is used in high temperature services. When cold formed extensively the grain size produces a visibly undulated surface called “orange peel”.


These nickel steel alloys are identical except for the higher level of carbon in alloy H, and the addition of up to 1. 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.

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. These rates are for carbide tools, Type C-2 for roughing, drilling and reaming. Siddhagiri Metals and Tubes Manufacturer: In the solution annealed condition, alloys H and HT have superior creep and stress rupture properties. This abstract is a brief summary of the referenced standard.

Typical applications for the alloy include ethylene pyrolysis, hydrocarbon cracking, cracking furnaces for vinyl chloride, diphenol and acetic acid. Siddhagiri Metals and Tubes Rating: Incoloy Round Bars is commonly used for valves, fasteners, tubing materials and mandrels. ASTM B Round Bars are used for process piping, heat exchangers, heating-element sheathing, carburizing equipment, and nuclear steam-generator tubing etc.

ASTM B – 06() Standard Specification for Nickel-Iron-Chromium Alloy Rod and Bar

High Performance Alloys stocks and produces Incoloy H in this grade in the following forms: The higher strength results from close control of carbon, aluminum and titanium contents in conjunction with a high temp anneal. Type C-3 for finishing. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.


The material shall conform to mechanical property requirements for tensile strength, yield strength, and elongation.

Excellent cold forming characteristics typically associated with the nickel-chromium alloys are exhibited with HT. Link to Active This link will b08 route to the current Active version of the standard. 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.

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

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

We offer Round Bars in different sizes, dimensions, specifications and standards as per client requirements. All the astj are manufactured as per international quality and safety standards.
