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 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.

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.

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.

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.

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.

Nickel Alloy C-276 and Hastelloy C-276 can be welded by all common welding methods (oxyacetylene is not recommended).

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.

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

Hastelloy B2 EFW Pipes is highly resistant to all concentrations and temperatures of hydrochloric acid.

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

Alloy B2 is a highly resistant material to most organic and inorganic acids. It is a reduction resistant material.

Hastelloy C276 Flanges are made up of the nickel chromium molybdenum alloy that is called hastelloy. The composition includes 50.99% nickel, 14.5% chromium, 15% molybdenum and carbon, manganese, silicon, sulfur, cobalt, iron and phosphorus in it.

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.

These alloys can function at very high temperatures and in severe mechanical stress environments, and also where high surface stability is required. They have high creep and oxidation resistance.

C22 has excellent resistance to chloride-induced localized corrosion, including pitting, crevice corrosion, and stress corrosion cracking.

Two criteria for evaluating oxidation resistance are weight change and depth of corrosion penetration. HASTELLOY X pipe bend excels in both respects due to the formation of a protective, tenacious oxide film.

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. Alloy C-22 has excellent resistance to a variety of chemical process environments, including strong oxidizing agents such as ferric and cupric chlorides, chlorine, hot fouling solutions (organic and inorganic), formic and acetic acid, acetic anhydride, and seawater and Brine solution. C-22 alloy resists the formation of grain boundary precipitates in the weld heat affected zone and is therefore suitable for most chemical process applications in as-welded conditions.

Hastelloy C276 is resistant to localized corrosion such as pitting and stress corrosion cracking.

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.

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.

This nickel-molybdenum alloy is typically used under extreme reducing conditions and has a much lower composition of carbon, silicon and iron than Hastelloy B (Alloy B). Screws made from this alloy are also known as UNS N10665 fasteners.

A butt weld pipe fitting is designed to be welded on site at its end(s) to connect pipe(s) together and allow change in direction or pipe diameter, or branching or ending.

This fitting then becomes part of a system for transporting fluids (oil, gas, steam, chemicals, …) in a safe and efficient manner, over short or long distances.

HASTELLOY C-2000 alloy (UNS N06200) is unique among the versatile nickel-chromium-molybdenum materials in having a deliberate copper addition.

Controlling other alloying elements such as iron and chromium

They combine the outstanding resistance to the oxidizing medium of Hastelloy C276 with superior resistance to non-oxidizing situations.
