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.

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.

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

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.

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.

Hastelloy C-2000 Fastener, also known by many as Alloy C-2000, is a versatile nickel-chromium-molybdenum alloy with excellent resistance to stress corrosion cracking and pitting corrosion. The C-2000 fastener (UNS N06200) is unique among other Hastelloy alloys with approximately 1.6% copper added to its chemical composition. These properties make them ideal for applications such as heat exchangers and industrial reactors. Hastelloy C2000 fasteners combine the excellent resistance to oxidizing media of C276 with excellent resistance to non-oxidizing environments, making it a unique alloy for protecting chemical process equipment under a variety of conditions, including fluids contaminated with iron ions .

Hastelloy C276 clad plate is a chromium, nickel, iron, and molybdenum grade that is solid-solution strengthened.

HASTELLOY X pipe bend is recommended especially for use in furnace applications because it has unusual resistance to oxidizing, reducing, and neutral atmospheres.

Hastelloy C22 flanges are available in different sizes and shapes. One can easily get it at their doorstep as per their specifications.

These have the advantage of nickel and molybdenum providing resistance against the most reducing environments. The oxidation resistance is also high in these materials due to the addition of the chromium content.

This alloy of flanges ensures excellent formability and weldability. Therefore these are cold and hot worked.

Alloy C276 Coils are often used in Pollution control, chemical processing, Waste treatment, Marine engineering, Pulp and paper production, and more.

HASTELLOY C276 is one of the few alloys resistant to wet chloride gas, hypochlorite and chlorine dioxide solutions.

C276 Elbow has excellent corrosion resistance to a wide range of concentrated hot acids and reducing environments and can be easily used in hot sulfuric and hydrochloric applications.

The chemical composition of Hastelloy B2 includes a very small amount of carbon content. Hence, the flanges produced from Hastelloy grade B2 tends to resist the formation of grain boundary carbide precipitates during welding in the weld heat-affected zone.

Hastelloy B3 Flanges has great resistance to cutter line, and heat affected zone attack.

These Hastelloy B2 Weld Neck Flanges should not be used in oxidizing media or where oxidizing contaminants are available in reducing media.

2.4819 has very good resistance to pitting, crevice corrosion and stress corrosion cracking, C276 is worth mentioning for its excellent resistance to aggressive media under oxidizing and reducing conditions.

It is used in flue gas desulfurization systems because of its excellent resistance to sulfur compounds and chloride ions encounted in most scrubbers.

Hastelloy C276 has a low carbon content to minimize grain boundary carbide precipitation during welding to maintain corrosion resistance in the heat affected zone of the welded joint

Alloy C276 (UNS N10276) is an austenitic nickel-molybdenumchromium alloy with a small addition
of tungsten.Hastelloy C-276 Alloy has excellent resistance to a wide variety of chemical process environments, including strong oxidizers such as ferric and cupric chlorides, hot contaminated media (organic and inorganic), chlorine, formic and acetic acids, acetic anhydride, and seawater and brine solutions.

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 B2 Welded Pipes is a wrought nickel-molybdenum alloy that can be used in the ¡®as welded¡¯ condition.

Hastelloy C-276 also has exceptional resistance to pitting, stress-corrosion cracking and oxidizing atmospheres, as well as excellent resistance to multiple different chemical environments.

Used when large radius bends or curves are required, this method passes a piece of pipe or tube through a series of three rollers in a pyramid configuration to achieve the desired curve.

Hastelloy B3 Weld Neck Flange is not recommended for use in the presence of ferric or cupric salts because these salts can cause premature failure.

C22 has excellent resistance to oxidation, carburization, and sulfidation at elevated temperatures. However, C22 should not be used at temperatures above 1250¡ãF due to the possible formation of embrittling phases.

The sheer variety of pipe bend sizes and materials also make them suitable for routing everything from hot or caustic liquids to maintaining pressure and movement in high viscosity liquids or those with suspended solids, such as Oil Sands slurry lines which contains a high concentration of silica sand.

Hastelloy B3’s distinguishing characteristic is its ability to maintain good ductility while transient exposure to intermediate temperatures.

The flanges also have 8.89 grams per cubic centimeter density and 1370 degrees melting point. The DIN 2.4617 Socket Weld Flanges and other flanges are used in high temperature, high corrosive and high stress applications due to the higher mechanical properties.

Alloy X pipe bend offers exceptional performance in furnace rolls or other industrial furnace applications because of the alloy’s strong resistance to oxidizing, reducing and neutral atmospheres.

Hastelloy C-276 is a nickel-molybdenum-chromium-tungsten alloy with excellent general corrosion resistance and good machinability. The alloy should be considered for use in environments requiring resistance to thermally contaminated inorganic acids, organic and inorganic chloride-contaminated media, chlorine, formic and acetic acids, acetic acid, acetic anhydride, seawater and brine solutions.

This nickel alloy provides excellent resistance to hydrochloric acid at all concentrations and temperatures. In additions, Hastelloy B2 pipe bend has excellent resistance to pitting, stress corrosion cracking and to knife-line and heat-affected zone attack.

Alloy B (UNS N10001) was developed to resist hydrochloric acid. Hastelloy B2 has replaced it. Alloy B3 (UNS N10675) is a newer variant with higher thermal stability. These alloy B2 bolts are a wrought nickel molybdenum alloy that can be used in the as-welded condition. It is highly resistant to hydrochloric acid of all concentrations and temperatures. Known as UNS N10665 bolts, these bolts are also resistant to stress corrosion cracking and pitting.
