Hastelloy

Each of them have structural differences. These flanges are made up of a nickel, chromium, molybdenum alloy that has 50% nickel 14% chromium, 15% molybdenum and carbon, manganese, silicon, sulfur, cobalt, iron and phosphorus in the composition.

There are different types such as the Hastelloy B2 Slip On Flanges , socket weld flanges, and welded neck flanges. These have 790MPa minimum tensile strength, 355MPa minimum yield strength and 40% elongation rate.

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.

The material is resistant to chlorides and acids so that the primary uses are in the acid processing, chemical, sea water and marine applications.

We are a manufacturer, trader, stockist, supplier, and exporter of ASTM B564 Hastelloy B2 Flanges that are known as ‘High-performance Flanges’ for their Nickel-Molybdenum combination, alloyed with a lower content of Iron, Silicon and Carbon, which makes them adept in administering control over the conveyance of reducing acids at higher temperatures.

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.

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.

These Hastelloy B2 Slip On Flanges can be machined using all the traditional machining methods. More than most other metals of similar chemistry, our Hastelloy B2 Spectacle Blind Flanges offers superior protection against powerful chemical corrosion and comes with one of the best high ¨C temp strengths of any steel.

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

Our Hastelloy B2 Lap Joint Flanges are also being offered in customized sizes and shapes to our customers. The extremely low carbon and silicon content of these Hastelloy B2 Socket Weld Flanges reduces precipitation of carbides and other phases in the heat ¨C affected zone of welds and ensures adequate corrosion resistance even in the welded condition.

Hastelloy C22 flanges have a wide range of usage in different industries. Hastelloy C22 alloys are mostly used in pharmaceutical industries for fittings and tubing, and it also helps to avoid contamination, which is mostly caused by corrosion.

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

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

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.

Bushings, also known as sleeve bearings, are just one specific type of bearing. They slide on the rod to provide extremely low friction movement. They are ideal for shock absorption and minimise energy consumption, noise and wear.

Hastelloy C276 bushings are widely used in the harshest environments such as chemical processing, pollution control, pulp and paper, industrial and municipal waste treatment, and recovery of sour natural gas.

Considered one of the most versatile corrosion-resistant alloys available, Hastelloy C276 bushings exhibit excellent resistance in a variety of chemical process environments, including ferric and cupric chlorides, thermally contaminated organic and inorganic media, Chlorine, formic and acetic acid, acetic anhydride, seawater, brine and hypochlorite and chlorine dioxide solutions.

Hastelloy C276 bushings have excellent resistance to strong oxidizing salt solutions such as ferric chloride and cupric chloride. Alloy C-276 has excellent phosphoric acid resistance at all temperatures below boiling point and concentrations below 65%.

Hastelloy C276 bushings have high nickel and molybdenum contents to provide good corrosion resistance in reducing environments.

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

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

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

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.

Hastelloy C-276 bushings are also used in sour gas wells, pulp and paper production, waste disposal, pharmaceutical and food processing equipment. Other important properties of this alloy Nickel Alloy C-276 and Hastelloy C-276 include its resistance to oxidizing agents.

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

Bushings are similar to thin tubes most commonly used in machinery with rotating or sliding shafts to increase efficiency and reduce vibration and noise. Bushings can be used for drilling operations in drill stands, hydraulic external gear pumps and motors.

In the case of Hastelloy-C276, the corrosion product was primarily a protective chromium oxide scale, although slightly thicker regions of the same oxide formed at the site of microcracks on the metal surface. Very little carburization was observed in this alloy before exposure for at least 1000 hours.

Hastelloy C276 flanges are made of a nickel-chromium-molybdenum alloy called Hastelloy. The composition includes 50.99% nickel, 14.5% chromium, 15% molybdenum and carbon, manganese, silicon, sulfur, cobalt, iron and phosphorus. Hastelloy C276 flanges have a high melting point of 1370 degrees Celsius.

We have a comprehensive inventory of nickel alloy forged fittings, socket weld and threaded fittings in all types, sizes, schedules and pressures. HT PIPE specializes in the manufacture of nickel alloy forged fittings that are in high demand in many applications in the naval, chemical processing, marine, petrochemical and refining, and oil and gas markets.

These are available in different types and grades such as Monel 400 Forged Threaded Elbow, Nickel 200 Forged Threaded Equal and Unequal Tee, Inconel 600 Threaded Equal and Unequal Cross, Incolloy 800 Threaded Half and Full Threaded Fittings, UNS S4400 Threaded Reducers, UNS S2201 threaded caps, Hastelloy C276 threaded reducing inserts, etc.
