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.

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.

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.

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.

The ANSI B16.5 Hastelloy C22 Weld Neck Flanges is an austenitic alloy grade that is considered to be versatile in nature. Chemically, the DIN 2.4602 Slip On Flange consists of elements such as nickel, chromium, molybdenum & tungsten as a primary base in the alloy.

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.

Another difference between Astm B626 Nickel Alloy C276 Welded Pipe and Alloy C is that Alloy C276 pipe has better machinability.

Hastelloy B2 pipe bend is a nickel-molybdenum alloy particularly suited for equipment handling reducing chemical environments.

Hastelloy C276 material is designed with good mechanical properties. They have a minimum tensile strength of 601Mpa and a minimum yield strength of 204Mpa. This material makes the alloy easy to machine and elongate.

Hastelloy 276 bolts and fasteners are suitable for most chemical applications in the welded condition. However, it should be noted that in environments where C-276 alloy weld joints are subject to attack, C-22 weld filler material should be considered. Hastelloy C276 socket head cap screws also have excellent resistance to pitting corrosion, stress corrosion cracking and oxidizing atmospheres up to 1900¡ãF.

Hastelloy B3 Ring Type Joint Flanges is ideally suited for applications requiring corrosion resistance superior to SS 304 and has good elevated temperature strength.

ASTM B619 welded pipe for the pharmaceutical industry has good corrosion resistance, especially to high purity water. And they also show good resistance to corrosion by buffer solutions used to prepare pharmaceuticals if ASTM B619 UNS N10276 is also exposed to cleaning supplies.

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.

C22 has excellent resistance to chloride-induced localized corrosion, including pitting, crevice corrosion, and stress corrosion cracking.

Although there are several variants of Hastelloy nickel alloys, Hastelloy C-276 is by far the most widely used.

Alloy X pipe bend is one of the most widely used nickel base superalloys for gas turbine engine components.

Considered one of the most versatile corrosion-resistant alloys available, Hastelloy C276 bushings exhibit excellent resistance in a variety of chemical process environments, including ferric and cupric chlorides, thermally contaminated organic and inorganic media, Chlorine, formic and acetic acid, acetic anhydride, seawater, brine and hypochlorite and chlorine dioxide solutions.

The material is resistant to chlorides and acids so that the primary uses are in the acid processing, chemical, sea water and marine applications.

Hastelloy C276 has a low carbon content to minimize grain boundary carbide precipitation during welding to maintain corrosion resistance in the heat affected zone of the welded joint

Hastelloy B3 studs are suitable for all applications that previously required the use of Hastelloy B2 alloy. Due to the enhanced thermal stability of Hastelloy B3 square bolts, the problems associated with manufacturing Hastelloy B2 parts are reduced.

Hastelloy C276 Plates, which has excellent corrosion resistance in reducing environments. Inconel C276 Plates is a nickel-molybdenum-chromium superalloy with an addition of tungsten designed to have excellent corrosion resistance in a wide range of severe environments.

Hastelloy B3 Long Weld Neck Flanges by definition contain at least 10 percent chromium.

Two criteria for evaluating oxidation resistance are weight change and depth of corrosion penetration. HASTELLOY X pipe bend excels in both respects due to the formation of a protective, tenacious oxide film.

A Pre-engineered steel is basically a that is made up of steel.

It is used in flue gas desulfurization systems because of its excellent resistance to sulfur compounds and chloride ions encounted in most scrubbers.

C2000 flanges have better temperature capabilities in hydrofluoric, sulfuric, and diluted hydrochloric acids due to the addition of copper.

As with most piping considerations, understanding the ideal uses for bent pipe in your design or project is essential to the proper operation of the finished system.

Alloy B-2 has poor corrosion resistance to oxidizing environments, therefore, it is not recommended for use in oxidizing media or in the presence of iron or copper salts, which may cause rapid premature corrosion failure.

Alloy C276 is a Ni-Cr-Mo alloy containing W and very low carbon and Si content.

Prefabrication can be of many different types and undertaken at many different scales, from fabrication of small components and sub-assemblies through to large welded and bolted assemblies requiring significant logistical challenge to transport to site

Hastelloy G30 is resistant to grain precipitation in high temperature regions. Hastelloy G30 fasteners exhibit physical properties such as thermal conductivity, elongation, and elastic modulus. Hastelloy G30 has properties such as yield strength and tensile strength. Our company supplies these fasteners to oil and gas, refineries, fertilizers, heat exchangers. These fasteners are also used in water treatment, sugar, dairy and food processing. It also shows density, area reduction, and coefficient of linear thermal expansion. Our Hastelloy G30 fasteners are highly resistant to hydrochloric and nitric acids. The alloy has superior resistance to industrial phosphoric acid. Hastelloy G30 fasteners perform well in corrosive environments.

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.

There are different types such as the Hastelloy B2 Slip On Flanges , socket weld flanges, and welded neck flanges. These have 790MPa minimum tensile strength, 355MPa minimum yield strength and 40% elongation rate.
