Hastelloy Alloys Directory
The Corrosion Resistant HASTELLOY alloys are widely used by the chemical processing industries. The need for reliable performance leads to their acceptance and growth in the areas of energy, health and environmental, oil and gas, pharmaceutical and flue gas desulfurization industries.

Hastelloy C2000 is available in a variety of sizes and thicknesses, this type of nickel-chromium-molybdenum alloy is renowned for its superior strength and corrosion resistance.

It is able to withstand a wide range of oxidizing and non-oxidizing chemicals, and exhibits outstanding resistance to pitting and crevice attack in the presence of chlorides and other halides.

Hastelloy C2000 Tubes are used in a broad range of industries including petrochemical processing, chemical processing equipment manufacturing, oil refineries and power plants.

This provides greatly enhanced resistance to sulfuric acid. It also has a high chromium content, to maximize its resistance to oxidizing chemicals and process streams contaminated with ferric ions and dissolved oxygen.

It demonstrates good resistance to neutral and reducing environments. This alloy creates a tenacious oxide, protective film that does not spall off, but it retains superior oxidation resistance at soaring temperatures.

Hastelloy C22 fasteners are a general-purpose grade composed of chromium, nickel, molybdenum and tungsten alloys. These designs are designed to increase resistance to pitting, stress corrosion cracking (SSC) and crevice corrosion cracking. It has high chromium content and good resistance to oxidizing media. The presence of molybdenum and tungsten provides good resistance to reducing media. Its nickel content provides admirable resistance to oxidizing aqueous media.

Hastelloy’s resistance to sulfuric acid makes it a common choice for protection from hydrogen sulfide (H2S), more commonly known as?sour gas.

Nickel alloys are some of the most useful materials for manufacturing technically superior pipes and tubes for industrial applications. Their inherent properties make them viable for a wide range of uses. Nickel alloys are exceptionally corrosion resistant and can be used in high-temperature environments.

Incoloy alloy is applied as the prefix name to several highly corrosion resistant high temperature strength metal alloys produced by Special Metals Corporation. Nickel alloys are excellent for heat exchangers in the chemical processing and nuclear industries. They’re used in steam generator tubing in the nuclear power industry, in high-temperature aircraft systems, and in oil and gas extraction programs where corrosion-, pressure- and temperature-resistant tubing is required

Hastelloy C2000 flanges are a special alloy for securing chemical process equipment under different conditions, including streams contaminated with ferric ions.

The flange is second most used joining method after selding. Flanges are used when joints need dismantling. It provides flexibility for maintenance. Flange connects the pipe with various equipment and valves. Breakup flanges are added in the pipeline system if regular maintenance in required during plant operation.
A flanged joint is composed of three separate and independent although interrdlated components; the flanges, the gaskets, and the bolting; which are assembled by yet another influence, the fitter. Special controls are required in the selection and application of all there elements to attain a joint, which has acceptable leak tightness.
A flange is a protruded ridge, lip or rim, either external or internal, that serves to increase strength (as the flange of an iron beam such as an I-beam or a T-beam); for easy attachment/transfer of contact force with another object (as the flange on the end of a pipe, steam cylinder, etc., or on the lens mount of a camera); or for stabilizing and guiding the movements of a machine or its parts (as the inside flange of a rail car or tram wheel, which keep the wheels from running off the rails). The term “flange” is also used for a kind of tool used to form flanges.

Hastelloy C-276 is a very popular alloy for us because of its high corrosion resistance in a wide range of environments. HT PIPE stocks a large stock of Hastelloy c726 bolts and fasteners. Hastelloy C-276 fasteners are made of nickel-molybdenum-chromium forged alloy, which is an improved forged version of alloy C. We stock Hastelloy c-276 bolts, nuts, screws, washers, studs, socket head cap screws, and many other fasteners for timely shipment.

Hastelloy C-4 is a nickel-chromium-molybdenum alloy with outstanding high temperature stability. It has high ductility and corrosion resistance. It’s high temperature resistance up to 1900 ¡ãF (1038 ¡ãC) makes it suitable for most chemical process application in the “as” welded condition.
Like other nickel alloys, it is ductile, easy to form and weld, and possesses exceptional resistance to stress corrosion cracking in chloride-bearing solutions (a form of degradation to
which the austenitic stainless steels are prone). With its high chromium and molybdenum
contents, it is able to withstand both oxidizing and non-oxidizing acids, and is resistant to
pitting and crevice attack in the presence of chlorides and other halides.

All of the common methods of welding can be used to weld Hastelloy C-276 alloy, although the oxyacetylene process is not recommended. Special precautions should be taken to avoid excessive heat input.

Inconel 600 flat washers are also non-magnetic and offer the perfect combination of high strength, hot and cold workability, and resistance to common forms of corrosion. Inconel Alloy 600 ferrules exhibit excellent toughness even at sub-zero temperatures and are suitable for use with most alkaline solutions and sulfides. To avoid stress corrosion cracking, Alloy 600 split washers are manufactured to be fully stress relieved prior to use.

These also enhances good resistance to pitting and crevice corrosion in tough climatic circumstances. These alloys of flanges also possess superior thermal conductivity and electrical resistivity.

Hastelloy C276 is one of the few materials that can withstand the corrosive effects of wet chlorine, hypochlorite and chlorine dioxide.

The pipes are having good stress corrosion cracking and pitting resistance ability.

Built-up sections are produced at the factory and is then transported to the original site and assembled. This concept is generally used to build Metro stations, industrial units, warehouses, etc.

Other corrosives Hastelloy C-22 has resistance to are oxidizing acid chlorides, wet chlorine, formic and acetic acids, ferric and cupric chlorides, sea water, brine and many mixed or contaminated chemical solutions, both organic and inorganic.

Thus these Hastelloy B2 Flanges are considered to be well suited to be used for most chemical process applications in an as-welded condition. Due to lower carbon content in the alloy, there is reduced precipitation of carbides as well as other phases in the heat-affected weld zones, which in turn ensures uniform resistance to corrosion in the flange.

A bushing is a type of bearing. Generally speaking, “bearings” facilitate movement between two components while reducing friction. Simple in design, a typical bearing has two surfaces that roll against each other, allowing the two mating parts to move without friction.

Hastelloy fasteners such as bolts, screws, nuts and threaded rods are ideal for use in a variety of moderately to severely corrosive acid environments. The most common grade of Hastelloy fasteners is Hastelloy C276 (2.4819), which is one of the most versatile corrosion-resistant nickel alloys, surpassing Inconel or Monel. There are also other special grades of Hastelloy fasteners that can address more niche corrosion problems.

Alloy B Its popularity has been hindered by its availability. All of these materials are good against reducing acids, but very hard against oxidizing acids. Due to the high molybdenum content, this alloy is relatively expensive than other alloys. At the same time, it has excellent corrosion resistance to medium-concentrated sulfuric acid and various non-oxidizing acids, good resistance to chloride stress corrosion cracking (SCC), and good resistance to various organic acids.

C-276 alloy has excellent resistance to pitting and to stress-corrosion cracking. It is also one of the few materials that withstands the corrosive effects of wet chlorine gas, hypochlorite, and chlorine dioxide.
