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.

It is able to withstand a wide range of oxidizing and non-oxidizing chemicals, and exhibits outstanding resistance to pitting and crevice attack in the presence of chlorides and other halides.

Hastelloy C2000 Tubes are used in a broad range of industries including petrochemical processing, chemical processing equipment manufacturing, oil refineries and power plants.

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.

Hastelloy B2 studs have poor corrosion resistance to oxidizing environments and are therefore not recommended for use in oxidizing media or in the presence of iron or copper salts as they may cause rapid premature corrosion failure.

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.

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

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

Hastelloy alloy C22 socket weld flanges have excellent resistance to reduce and oxidizing media. It also helps to resists the formation of grain-boundary precipitates in the heat-affected zone.

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.

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.

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.

Alloy C276 bar welding products are used as a matching composition filler material for welding C276 alloy forged and cast products in dissimilar welding applications including other NiCrMo alloys and stainless steels, as well as for surfacing or cladding of steel. Parts thermoformed in HASTELLOY C-276 alloy bar should, if possible, be solution heat treated prior to final fabrication or installation.

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 a corrosion-resistant nickel-molybdenum-chromium alloy that is widely used in a variety of industrial applications, particularly in environments where strong acids and oxidizing agents are present.

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

Hastelloy B2 Seamless Pipes is a solid solution strengthened, nickel ¨C molybdenum alloy, typically used in extreme reducing conditions.

Process piping systems rarely travel in a straight line from process to process.

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 C-276 is a very popular alloy for us for the reason that it is highly anticorrosive in a broad range of enveronments. Thunder Threads? stocks an immense inventory of hastelloy c726 bolts and fasteners. Hastelloy C276 Fasteners is a wrought corrosion-resistant alloy that resists the development of grain boundary precipitates that degrade corrosion resistance.

G30 alloy can prevent the formation of grain boundary precipitation in the heat affected zone of welding, so its welded products are suitable for various chemical treatment engineering applications.

Hastelloy C276 is a nickel-molybdenum-chromium superalloy with an addition of tungsten designed to have excellent corrosion resistance in a wide range of severe environments.Alloy C-276 is one of the most universally corrosion resistant alloys available today. It is used in a variety of environments ranging from moderately oxidizing to strong reducing conditions. Alloy C-276 has exceptional resistance to sulfuric acid, hydrochloric acid, formic acid, acetic acid, chlorides, solvents, wet chloride gas, hypochlorite and chlorine solutions.

C276 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 general name of the good board.
Thin steel plate refers to a steel plate with a thickness of not more than 3 mm. The commonly used thin steel plate thickness is 0.5-2MM, which is divided into sheet and coil supply. Thin
The steel plates are generally B-type steels, cold-rolled or hot-rolled steel plates with steel grades B0-B3. Requirements for thin steel plates: smooth, smooth surface, thick
The degree of uniformity, allowing a tight iron oxide film, must not have cracks, scarring and other defects. The process is divided into hot rolled sheet steel and cold rolled sheet
plate. Mainly used in Changlin Dongfeng fans, automobiles, electrical equipment, vehicles, agricultural machinery, containers, steel furniture, etc.
Thick steel plates refer to steel plates with a thickness greater than millimeters. Thick steel plate is divided into extra-thick steel plate and medium-thick steel plate.
Medium and heavy steel plates refer to steel plates with a thickness greater than 3 mm and less than 50 mm. Medium and thick steel plates are mainly used in shipbuilding, boilers, bridges
Armor and high-pressure vessel shells, etc.
