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 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.

The low carbon minimizes carbide precipitation during welding to maintain resistance to intergranular attack in heat-affected zones of welded joints.

Hastelloy B3 Socket Weld Flanges is dual-certified to meet both SS 316 and SS 316L.

HASTELLOY C-276 alloy has excellent resistance to a variety of chemical process environments, including strong oxidizing agents such as ferric and copper chlorides, hot fouling media (organic and inorganic), chlorine, formic and acetic acids, acetic anhydride, and Seawater and brine solutions. It can be used in flue gas desulfurization systems due to its excellent resistance to sulfur compounds and chloride ions in most scrubbers.

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.

Today, Alloy B2 with restricted chemistry can be used in the welded condition and is less susceptible to SCC under many conditions. As always, care must taken in selecting the right alloy for the desired application.

Hastelloy C22 Spectacle Blind Flanges is also in a wide variety of hazardous waste management technologies where high corrosion ¨C resistance of critical equipment is required for reliability, safety, and cost effectiveness / reduced maintenance.

The low carbon content in the 2.4819 alloy C276 tube minimizes carbide precipitation. Carbide precipitation is a phenomenon that occurs during welding of various alloy grades.

Hastelloy Cold Drawn Tubes and Tubes – Offers good machinability, higher strength and constant degrees of freedom compared to hot rolled and cold drawn tubes. These pipes work more efficiently because their microstructure is very constant and also have increased physical properties.

Exposures like this are regularly experienced during heat treatments that are linked with fabrication.

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

Hastealloy is a term that refers to a group of corrosion resistant metal mixtures that are based on nickel. Hastealloys have a unique combination of properties that provide them with significantly stronger corrosion resistance capabilities compared to traditional alloys. As such, it was widely accepted in the chemical process and associated industries, and now has a 50-year-old track record of proven performance in a vast number of corrosive chemicals.

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.

The exceptional corrosion resistance of C22 has promoted its use in many different markets wherever harsh environments are encountered, including the chemical process, pharmaceutical, food processing, oil and gas, power generation, and the paper industries.

HASTELLOY(r) B-2 is a wrought nickel-molybdenum alloy that can be used in the ¡®as welded¡¯ condition.

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.

Hastelloy C-276 is easily fabricated by welding, using methods similar to those used for nickel-based alloys.

G30 alloy can prevent the formation of grain boundary precipitation in the heat affected zone of welding

The best feature of Hastelloy C22 threaded flanges is that it has the best resistance to oxidizing aqueous media and a wide range of chemical process environments, including oxidizers like ferric acids, seawater, and chloride solution.

Hastelloy B2 fasteners are primarily used for excellent resistance to reducing environments such as hydrogen chloride gas, sulfuric acid, acetic acid and phosphoric acid. Like other Hastelloys, B2 fasteners can be used in the as-welded condition because they resist the formation of grain boundary carbide deposits in the weld heat-affected zone. Due to reduced ductility, B2 fasteners are not recommended for use between 1000¡ãF and 1600¡ãF.

Alloy C276 Forged Flange 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. The Hastelloy C276 Flanges have high melting point of 1370 degrees Celsius. This high melting point allows for higher operating temperatures of the flanges. The material also has 790MPa minimum tensile strength and 355MPa minimum yield strength.

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.

This alloy is having chemistry design for achieving thermal stability level that is superior to predecessors like B2 alloy. It is having good resistance to corrosion, pitting and stress corrosion cracking and to knife line as well as the heat affected zone attack.

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

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 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.

The corrosion resistance property of the alloy is credited to the addition of both Molybdenum and nickel.

C-276 alloy is normally solution heat-treated at 2050¡ãF (1121¡ãC) and rapid quenched. If possible, parts which have been hot-formed should be solution heat-treated prior to final fabrication or installation.

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 X pipe bend is widely used for a variety of chemical processing parts, including retorts, pyrolysis tubing, and muffles due to its exceptional resistance to stress-corrosion cracking.

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).
