Historical Version s – view previous versions of standard. Incoloy HT has further modifications to the combined titanium and aluminum levels. Incoloy HT can be welded by the common techniques used on stainless steels.

ASTM B – 01 Standard Specification for Nickel-Iron-Chromium Alloy Rod and Bar

Power plants use them for super-heater and v408 tubing. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 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.

For information on machining, click here. This modification was to control carbon. Link to Active This link will always route to the current Active version of the standard. Type C-3 for finishing. The material shall asstm 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.

Siddhagiri Metals and Tubes Manufacturer: Machining Type Suggested starting rates are: Looking for some more information? Typical applications for the alloy include ethylene pyrolysis, hydrocarbon cracking, cracking furnaces adtm vinyl chloride, diphenol and acetic acid. Alloy HT Rods asfm 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.


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

Mechanical Property Requirements Ultimate Tensile, min. In the solution annealed condition, alloys H and HT have superior creep and stress rupture properties.

It is used in high temperature services. The material shall conform to mechanical property requirements for tensile strength, yield strength, and elongation. These Nickel Round Bars are used for Heat exchangers, Pressure vessels, Dampers, Nitric acid catalyst supports, Reformer outlet pigtails and manifold, and more. Please give us a Review. The general corrosion resistance is excellent.

Common uses of Incoloy include deployment in gas turbines, subservice safety valves, aircraft engines, thrust reversers, and industrial fasteners. 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 alloy is also used for valves, fittings and other components exposed to corrosive attack from to deg F. High Performance Alloys stocks and produces Incoloy H in this grade in the following forms: 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. Incoloy Round Bars is a nickel-chromium alloy bar that contains supplemental amounts of columbium, iron, molybdenum, aluminum, and titanium.

We offer Round Bars in different sizes, dimensions, specifications and standards as per client requirements. Incoloy Round Bars has excellent cryogenic and heat ranges.

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

The nickel content makes the alloys highly resistant to both chloride stress-corrosion cracking and to embrittlement from precipitation of sigma phase. Incoloy was the first of these alloys and it was slightly modified into Incoloy H. These Round bars have various applications in the industry. ASTM B B4408 Bars are used for process piping, heat exchangers, heating-element sheathing, carburizing equipment, and ast steam-generator tubing etc. Incoloy H material can be supplied in random lengths, cut to order or machined to customer requirements.


This abstract is a brief summary of the referenced standard. Siddhagiri Metals and Tubes Rating: Offer on Fasteners Sitemap. Request quote on this grade. Machining includes drilling, threading, milling, CNC shapes, turning, tapping, flanges and others.

The H modification was to control carbon 0. IncoloyH, and HT are nickel-iron-chromium alloys with good strength and excellent resistance to oxidation and carburization in high-temperature exposure. The material shall conform to mechanical property requirements for tensile strength, yield strength, and elongation.

Humble, Texas fax Incoloy Round Bars have high strength properties, heat treatable, good corrosion resistance, formability and weldability.

These nickel steel alloys are identical except for the higher level of carbon in alloy H, and the addition of up to 1. The chemical balance allows the alloy to exhibit excellent resistance to carburization, oxidation and nitriding atmospheres. 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. The asm strength results from close control of carbon, aluminum and titanium contents in conjunction with a high temp anneal.

Incoloy Aatm Bars is commonly used for valves, fasteners, tubing materials and mandrels.
