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.

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.

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 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 G-30 alloy is a high-chromium nickel-based alloy that exhibits corrosion resistance superior to most other nickel- and iron-based alloys in commercial phosphoric acid and in many complex environments containing highly oxidizing acids such as nitric/hydrochloric acid, Nitric/hydrofluoric and sulfuric acid. The resistance of G-30 alloy to the formation of grain boundary precipitates in the heat affected zone makes it suitable for the as-welded condition in most chemical processing 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 suitable for off-shore applications where hydrogen-sulphide stress corrosion cracking resistance is essential.

Hastelloy’s resistance to sulfuric acid makes it a common choice for protection from hydrogen sulfide (H2S), more commonly known as?sour gas.

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.

INCONEL alloy C-276 (UNS N10276/W.Nr. 2.4819) is known for its corrosion resistance in a wide range of aggressive media.

Alloy C276 plate is a high strength grade designed to be thicker than 6mm. The panels have a minimum tensile strength of 601mpa and a minimum yield strength of 204.8mpa. C276 composite panels are made by bonding two or metals in place. Meanwhile, Alloy C276 is resistant to oxidation at 1800¡ãF in the open air. However, alloy C276 is generally not recommended for high temperature service. The high molybdenum content makes alloy C276 prone to catastrophic oxidation under stagnant conditions, such as under solid deposits.

Nickel alloys are excellent for heat exchangers in the chemical processing and nuclear industrie.Hastelloy Piping Systems are widely accepted by plant operations management and maintenance specialists who appreciate their toughness and ability to withstand very aggressive fluids.

Controlling other alloying elements such as iron and chromium

Hastelloy fasteners such as bolts, screws, nuts and threaded rods are ideal for use in a variety of moderately to severely corrosive acid environments. The most common grade of Hastelloy fasteners is Hastelloy C276 (2.4819), which is one of the most versatile corrosion-resistant nickel alloys, surpassing Inconel or Monel. There are also other special grades of Hastelloy fasteners that can address more niche corrosion problems.

Nickel alloys are some of the most useful materials for manufacturing technically superior pipes and tubes for industrial applications.Nickel Pipe is a metal pipe that is made up of an alloy that has primarily nickel and other elements in its composition.

Hastelloy B3’s distinguishing characteristic is its ability to maintain good ductility while transient exposure to intermediate temperatures.

Hastelloy B3 pipe has good resistance to stress corrosion cracking that is chloride induced. The good resistance to a wider range of organic acids makes Hastelloy B2 pipes a popular product.

Alloy 22 (UNS N06022) is the most versatile Nickel Chromium Molybdenum Tungsten alloy with controlled Iron. Due to Alloy 22’s content this alloy exhibits excellent resistance to both oxidising and reducing acid environments as well as those containing mixed acids.

Hastelloy C-276 alloy has excellent resistance to a variety of chemical process environments, including strong oxidizing agents (such as ferric chloride and cupric chloride), hot fouling media (organic and inorganic), chlorine, formic and acetic acid, acetic anhydride, and Seawater and brine solutions.

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.

It is used in flue gas desulfurization systems because of its excellent resistance to sulfur compounds and chloride ions encounted in most scrubbers. C 276 alloy has excellent resistance to pitting and to stress corrosion cracking. It is also one of the few materials that withstands the corrosive effects of wet chlorine gas, hypochlorite, and chlorine dioxide.

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.

Hastelloy C276 Flanges Hastelloy C276 Flanges are made up of the nickel chromium molybdenum alloy that is called hastelloy. The composition includes 50.99% nickel, 14.5% chromium, 15% molybdenum and carbon, manganese, silicon, sulfur, cobalt, iron and phosphorus in it. The Hastelloy C276 Flanges have high melting point of 1370 degrees Celsius. This high melting point allows for higher operating temperatures of the flanges. The material also has 790MPa minimum tensile strength and 355MPa minimum yield strength.

While fitting and sizing bent pipes might seem complex at first, a basic understanding of the measurements used make matching them to your existing system or integrating them into a new design straightforward.

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.
