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.

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.

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 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 C276 is one of the few alloys resistant to wet chloride gas, hypochlorite and chlorine dioxide solutions.

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.

These flanges are usually welded or screwed. In those instances where welding or bolting the flange is not possible, many industries prefer using WNR 2.4602 Threaded Flanges.

Hastelloy C276 alloy hollow rods tend to exhibit excellent resistance to localized corrosion and oxidizing media as well as reducing media.

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.

While there are slight variances to different hot pipe bending methods, nearly all are a form of induction bending.

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.

Hastelloy C22, also known as Alloy C22, is a general purpose austenitic nickel-chromium-molybdenum-tungsten alloy with enhanced resistance to pitting, crevice corrosion and stress corrosion cracking. High chromium content provides good oxidation resistance, while molybdenum and tungsten content provides good reduction resistance. Hastelloy C22 alloy also has excellent resistance to oxidizing aqueous media, including wet chlorine and nitric acid-containing mixtures or oxidizing acids containing chloride ions.

G30 alloy can prevent the formation of grain boundary precipitation in the heat affected zone of welding

Nickel alloys are alloys with nickel as principal element. Complete solid solubility exists between nickel and copper. Wide solubility ranges between iron, chromium, and nickel make possible many alloy combinations.Steel plates are often used for structural and construcation applications, pressure vessels, marine and off shore equipment, and military applications. The grade, elements and parameters of a steel plate are also improtant in how it is used.

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 B2 is also known as UNS N10665 that is corrosion resistant and solid solution molybdenum-nickel alloy.

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

Hastelloy C276 low carbon content minimizes carbide precipitation during welding to maintain corrosion resistance of welded structures. This nickel alloy resists the formation of grain boundary deposits in the weld heat-affected zone, making it suitable for most chemical process applications in the as-welded state.
