Alloy B2 should not be used at temperatures between 1000¡ãF and 1600¡ãF as the alloy forms secondary phases that could decrease the ductility of the material.

What distinguishes the Hastelloy B3 fastener from its predecessor is its excellent ductility during transient exposure to intermediate temperatures (i.e. machining, heat treatment) due to its lower carbon content. This nickel-molybdenum alloy is typically available in bar, wire, sheet and plate form. Hastelloy B-3 fasteners are commonly used in vacuum furnaces and petro/chemical production lines.

The high molybdenum content of Hastelloy?* C276 provides the alloy with its excellent resistance to pitting and crevice corrosion.

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.

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

Alloy C276 is an alloy that excels in a range of corrosive environments. It is resistant to strong oxidizing chlorides, reducing acids, hot sea water and saline solutions.

Hastelloy C-4 is a nickel-chromium-molybdenum alloy with outstanding high temperature stability. It has high ductility and corrosion resistance. It’s high temperature resistance up to 1900 ¡ãF (1038 ¡ãC) makes it suitable for most chemical process application in the “as” welded condition.
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). With its high chromium and molybdenum
contents, it is able to withstand both oxidizing and non-oxidizing acids, and is resistant to
pitting and crevice attack in the presence of chlorides and other halides.

Chemical processing plants use high-end, high-precision tubing, such as Ni C276 hot-worked tubing. There are also resistance welded pipes. Hastelloy C276 Alloy EFW Tubing is easy to use. It can be welded without much precipitation. This feature helps the material retain its shape and not corrode even after applying field welding.

Hastelloy G30 is a nickel-based alloy with a high chromium content that provides superior corrosion resistance to commercial phosphoric acid and many highly oxidizing acid media.

Hastelloy C-22 (UNS N06022) pipe bends and fittings in stock, allowing for a quick turnaround. Hastelloy C-22 has excellent resistance to aggressive oxidizing aqueous media including wet chlorine and mixtures containing nitric acid or oxidizing acids with chlorine ions.

HASTELLOY(r) C276 can be formed by cold working using conventional techniques.

Alloy B-2 has poor corrosion resistance to oxidizing environments, therefore, it is not recommended for use in oxidizing media or in the presence of iron or copper salts, which may cause rapid premature corrosion failure.

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.

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.

Hastelloy C-276 is a nickel-molybdenum-chromium alloy with excellent corrosion resistance in severe environments.

The flange is second most used joining method after welding. Flanges are used when joints need dismantling. It provides flexbility for maintenance. Flange connects the pipe with various equiment and valves. Breakup flanges are adde din the pipeline system if regular maintenance in required during plant operation.
A flanged joint is composed of three separate and independent although interrelated components; the flanges, the gaskets, and the bolting; which are assembled by yet another influence, the fitter. Special controls ae required in the selection and application of all these elements to attain a joint, which has acceotable leak tightness.

Hastelloy B3 is a nickel-molybdenum alloy with profound resistance to stree-corrosion cracking, pitting, corrosion and thermal stability greater to that of alloy B2.

Hastelloy C2000 lap joint flanges are used for heat treatment applications. They have very little carbon content and high nickel content, which makes them much stronger than any other flanges.

Forged Pipe Fittings(Socket Weld and Threaded) are made in accordance to ASME B 16.11, MSS-SP-79/83/95/97 and BS3799 Standards, and are used to connect nominal bore schedule pipes and pielines.

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

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

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.

Alloy C22 is a nickel-chromium-molybdenum solid solution strengthened super-alloy with a nominal chemical composition of 56% nickel, 22% chromium, and 13% molybdenum, with additions of iron, tungsten, and cobalt.

According to the flange size, wall thickness and diameters, the pressure classes vary from class 150 through class 2500. There are also different faced flanges such as the ring type joint Alloy B2 RTJ Flange, raised face flange and flat face flange.
