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.

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.

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.

These alloys of flanges are exceptionally resistant to stress corrosion cracking petrochemical applications. Moreover, the molybdenum content results in outstanding strength in solid solution alloy that considers excellent fabrication attributes.

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 threaded flanges have the best weldability.

Nickel alloys are some of the most useful materials for manufacturing technically superior pipes and tubes for industrial applications. Their inherent properties make them viable for a wide range of uses. Nickel alloys are exceptionally corrosion resistant and can be used in high-temperature environments.

B2 has significantly lower carbon, silicon and iron compared to its¡¯ predecessor, Alloy B (UNS N10001), making the alloy less susceptible to decreased corrosion resistance in the weld zone, 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.

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.

Controlling other alloying elements such as iron and chromium

Prefabricated steel s as the name itself sounds, is made of pre engineered steel. Fabrication is done in controlled environment inside the factory and then sent to client location for assembly.

Brushing these boards with stainless steel wire after the welding operation usually removes the hot color and likewise creates surface areas that do not require additional pickling.

Welding of this alloy is similar to that of the C-22 alloy. Gas tungsten arc welding (GTAW) and shielded metal arc welding (SMAW) are commonly used to weld C-276 alloys.

It is recommended that the alloy be welded in the solution annealed condition with C-276 filler metal.

This alloy of flanges ensures excellent formability and weldability. Therefore these are cold and hot worked.

Although Alloy C276 plate has a higher rate of work hardening compared to its austenitic counterpart, in-process annealing may be required if nickel alloy C276 plate is to be work hardened to a higher degree. Solution annealing may be required if the deformation of the nickel C276 strip exceeds 15%.

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.

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 also resists carburization and nitriding, two common conditions which often lead to early failure in high-temperature alloys. After 100 hours in petroleum coke, four other materials were completely penetrated by carburization and whereas.

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.

Light gauge steel framing is an integral part of modular construction as it is strong, lightweight, durable, accurate, free from long-term movement and is well proven in a wide range of applications.

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.

Solved other issues concerning fabricability. Stringent chemistry control along with years of development has resulted in the alloy used today, both in Alloy B2 and Alloy B-3.

Hastelloy X alloy fasteners are precisely engineered by our experts to ensure the finest steel is used in industrial processes. Because of its unfamiliar resistance to reducing, neutral and oxidizing environments. Hastelloy X alloy fasteners have also been found to have significant SCC resistance in petrochemical functions. Hastelloy X alloy is a chromium-iron-nickel-molybdenum superalloy with excellent high temperature efficacy, machinability and oxidation resistance.
