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.

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 Tubes are used in a broad range of industries including petrochemical processing, chemical processing equipment manufacturing, oil refineries and power plants.

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.

C-22 is used in severely corrosive media with high chloride and temperature applications such as buffer solutions, active pharmaceutical ingredients (API), fabric softeners, cleaning supplies, and fish, soy and chili sauce.

Hastelloy C22 machined gaskets also have the best resistance to environments that encounter reducing and oxidizing conditions in the process stream. Hastelloy C22 round washers can be welded, forged, hot upset and impact extruded. Typical chemical process industry (CPI) applications for Hastelloy C22 punch gaskets include reactors, heat exchangers and columns. Hastelloy C22 flat washers have excellent resistance to pitting corrosion, stress corrosion cracking, tool marks and weld heat affected zone erosion.

HASTELLOY C276 is not prone to grain boundary precipitation in the as welded condition and therefore suitable for many chemical process applications.

The alloy is forged between 2250/1750oF (1230/955oC) and then soaked at the forging temperature for 30 minutes per inch of billet or ingot section thickness. Forging should begin immediately, the billet is removed from the reheat furnace, a 25/40% reduction helps retain as much internal heat as possible. For optimum corrosion resistance, forged parts should be subsequently annealed. See Heat Treatment.

The high molybdenum content imparts resistance to localized corrosion such as pitting.

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 B3 bolts are also known as alloy B-3 bolts and can be found under UNS N10675. This alloy is extremely resistant to pure hydrobromic, sulfuric and hydrochloric acids. Many industries, including the chemical industry, consider the alloy easy to machine, and its ductility allows machinists to easily form and even weld.

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. It has high chromium content and good resistance to oxidizing media. The presence of molybdenum and tungsten provides good resistance to reducing media. Its nickel content provides admirable resistance to oxidizing aqueous media.

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.

HASTELLOY C-2000 alloy is available in the form of plates, sheets, strips, billets, bars, wires, pipes, tubes, and covered electrodes. Typical chemical process industry (CPI) applications include reactors and heat exchangers.

These also enhances good resistance to pitting and crevice corrosion in tough climatic circumstances. These alloys of flanges also possess superior thermal conductivity and electrical resistivity.

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.

The flanges are furnished in solution heat treated circumstances, thus these are heat treated at 2150 degree F and get cooled rapidly.

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.

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.

These flanges demonstrate outstanding toughness and hardness. Thus it exhibits superior ductility after prolonged exposure at a temperature of 650, 760, 870 degree C.

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.

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.
