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.

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 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 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.

In comparison to the other Hastelloy alloys, Hastelloy C2000 Flanges were designed to provide more adaptability. In addition to adding a little amount of copper (1.6%), this was accomplished by enhancing the proportion of chromium and molybdenum.

The use of modular construction is directly influenced by the client¡¯s requirements for speed of construction, quality, added benefits of economy of scale, as well as single-point procurement.

Hastelloy C276 is an extremely versatile material that has been used in a variety of harsh environments. It exhibits corrosion resistance to chloride-containing media, organic acids, oxidizing media, reducing acids, seawater and brine, and sulphur-containing flue gas. Hastelloy C276 replaces Alloy C (UNS N10002), which has slightly lower chromium and molybdenum contents. The high nickel, molybdenum and tungsten contents make them expensive compared to austenitic stainless steels. It is by far the most popular super alloy.

Hastelloy C22 Spectacle Blind Flange is the ability of the alloy to resist corrosion. For instance, Hastelloy C22 is known to have enhanced resistance to pitting, crevice corrosion as well as stress related corrosion cracking.

It is used in flue gas desulfurizations systems because of its excellent resistance to sulfur compounds and chloride ions encountered in most scrubbers. C-276 alloy has excellent resistance to pitting and to stress- corrosion cracking.

The flanges are produced through different techniques as the ASTM B564 Hastelloy B2 Threaded Flanges, screwed flanges, forged flanges and plate flanges. The threaded flanges are used with threaded pipes and the female threaded flanges connect to the male threaded pipe ends.

Alloy N10675 is a high corrosion resistant nickel molybdenum Alloy. This alloy is characterized by a high resistance against hydrochloric acid and other reducing media in a wide range of temperature and concentration.

Alloy C276 is a nickel, chromium and molybdenum alloy. Hastelloy C276 is designed for excellent corrosion and oxidation resistance in a variety of environments. These alloys also show resistance to pitting and crevice corrosion.

Hastelloy can be used with all common welding methods, but oxyacetylene and submerged arc processes are not recommended when the manufactured product is intended for corrosion service.

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 the most common corrosion resistant material currently available, but it is not foolproof. Metals should not be exposed to high temperature, strong acid environment. Also, it is easier to work with cold working practices; hot working makes it easier to harden. If hot working, the temperature should be maintained between 1600¡ãF and 2250¡ãF.

Hastelloy C-276 alloy can be forged, hot-upset, and impact extruded. Although the alloy tends to work-harden, it can be successfully deep-drawn, spun, press formed or punched.

Hastelloy B2 is a nickel-molybdenum alloy with significant resistance to reducing environments, such as hydrogen chloride gas and sulfuric, acetic and phosphoric acids.

Hastelloy B2 studs have poor corrosion resistance to oxidizing environments and are therefore not recommended for use in oxidizing media or in the presence of iron or copper salts as they may cause rapid premature corrosion failure.

Alloy B2 also has excellent resistance to pitting and stress corrosion cracking.

Hastelloy G30 Hastelloy alloy is widely used in phosphoric acid equipment, sulfuric acid equipment, nitric acid equipment, nuclear fuel reprocessing

Hastelloy C22 washers are composed of a nickel-chromium-molybdenum alloy that, like other high-nickel alloys, is highly ductile, making it easy to machine, weld, and fabricate into nuts, bolts, and screws. Hastelloy C-22 washers are made of Haynes International trademark alloy, also known as UNS N06022 or alloy 22 fasteners. C-22 fasteners are made from one of the more popular Hastelloy alloys. It is highly resistant to oxidizing/non-oxidizing chemicals, making it an excellent alloy for columns, heat exchangers and reactors in the chemical processing industry.

Machining of Hastelloy UNS N10276 polished plates is best done in the annealed condition. Since this particular alloy grade is prone to work hardening, only low cutting speeds are required.

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.

As the most pipe bending methods are quite cost-efficient, using bent pipes and tubes will have a minimal impact on the overall design budget when using the ideal length and sizing for your application.

Hastelloy B2 is a nickel-molybdenum alloy especially suitable for handling equipment that reduces chemical environments. Such as applications in chemical processing industries involving sulfuric acid, phosphoric acid, hydrochloric acid and acetic acid.

Hastelloy C-276 fasteners and other products in the Hastelloy family have excellent resistance to corrosion and oxidizing and reducing chemicals. Due to its adaptability, Hastelloy C-276 alloy can be used in problem areas and is more likely to occur in process areas. Hastelloy 276 bolts and fasteners are suitable for most chemical applications in the welded condition. However, it should be noted that in environments where C-276 alloy weld joints are subject to attack, C-22 weld filler material should be considered.

The B2 forged fitting is the cornerstone of a strong comic, and the composition of Hastelloy leverages it to have the necessary strength and quality standards to help it withstand a lot of stress for years to come.

Hastelloy alloy C22 socket weld flanges have excellent resistance to reduce and oxidizing media. It also helps to resists the formation of grain-boundary precipitates in the heat-affected zone.

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.

The term “flange” is also used for a kind of tool used to form flanges.

These alloys of flanges are basically non-magnetic but feature superior higher strength at a temperature range of 1500 degree F. whereas show good oxidation resistance up to 2200 degree F.

ANSI B16.11 Hastelloy B2 plugs have excellent resistance to oxidizing aqueous media including wet chlorine and mixtures including oxidizing or nitric acid.

These salts may develop when hydrochloric acid comes in contact with iron and copper. Therefore, if this alloy is used in conjunction with iron or copper piping in a system containing hydrochloric acid, the presence of these salts could cause the alloy to fail prematurely.

Plates are designed by continuous rolling and casting or, in most instances, steel is processed into a bullet then hot rolled to be shaped in its final plate thickness. Akin to steel plates, rolled ring forgings are forged in the same process ¨C it differs only in terms of rolling directions.
For cups having comparative large thickness and plates having
complicated cross-sectional shapes, plate forging is more useful than billet forging due to due to
comparatively small change in shape.
