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.

Controlling other alloying elements such as iron and chromium

The outstanding oxidation resistance of HASTELLOY X pipe bend is illustrated below. Tests were conducted by exposing samples to dry air at 2000 Deg. F. and to dry air pressurized to 300 psi at 1750 Deg. F.

Hastelloy B2 Round Pipes (UNS N10665) is used for most chemical process applications in the welded condition, gasoline refining.

HASTELLOY C276 is a Nickel-chromium-molybdenum wrought alloy that is considered the most versatile corrosion resistant alloy available. Alloy C-276 is frequently used in many industries, including chemical and petrochemical processing, oil and gas, power generation, pharmaceutical, pulp and paper production and waste water treatment. End use applications include stack liners, ducts, dampers, scrubbers, stack gas reheaters, heat exchangers, reaction vessels, evaporators, transfer piping and many other highly corrosive applications.

In the case of Hastelloy-C276, the corrosion product was primarily a protective chromium oxide scale, although slightly thicker regions of the same oxide formed at the site of microcracks on the metal surface. Very little carburization was observed in this alloy before exposure for at least 1000 hours.

Hastelloy C22 flanges have a wide range of usage in different industries. Hastelloy C22 alloys are mostly used in pharmaceutical industries for fittings and tubing, and it also helps to avoid contamination, which is mostly caused by corrosion.

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).

Hastelloy C276 bolts are used in heavy duty applications due to their excellent mechanical quality. This material is one of the most corrosion-resistant materials used in the world. The bolt can be used with welding without the effects of grain boundary precipitation because it has virtually no carbide precipitation during welding. Hastelloy C276 bolts can be used in acid treatment applications because the material resists most corrosive conditions, including heavy sulfur compounds and chloride ions. This quality makes it suitable for desulfurization machinery, flue gas machinery and other harsh conditions.

B3 Hastelloy Flanges has some excellent features to offer like fine finish, accurate range, and durable.

Today, Alloy B2 with restricted chemistry can be used in the welded condition and is less susceptible to SCC under many conditions. As always, care must taken in selecting the right alloy for the desired application.

Pipe or tube is bent using a combination of dies and other various components working in a rotary action.

Hastelloy C-276 has superior resistance to localized corrosion as well as oxidizing.C276 alloy is suitable for many chemical process applications.

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.

Alloy C276 Forged Flange 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.

Hastelloy C22 alloy includes nickel, chromium, molybdenum, and tungsten, which result in extreme resistance to pitting and stress corrosion cracking.

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

La aleacion tambien es resistente a soluciones y compuestos de cloruro, muchos de los cuales son altamente corrosivos. Por ejemplo, los reductores de aleacion de niquel C276 son resistentes no solo a los medios organicos e inorganicos termicamente contaminados, sino tambien a los cloruros ferricos y c¨²pricos, asi como al cloro, el agua de mar y la salmuera.

Fasteners play a critical role in the construction of all sorts of everyday objects. If you¡¯ve done any DIY projects, you¡¯ve likely used fasteners to help get the job done.Fasteners are used for fastening and securing materials such as wood, metal, plastic, or concrete. They include nuts and bolts, threaded rods, structural bolts, machine screws, wedge anchors, washers, rivets, and more in a variety of types and sizes, including metric and inch.

It is also one of the few materials that withstands the corrosive effects of wet chlorine gas, hypochlorite, and chlorine dioxide.

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.

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

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

Hastelloy is a corrosion-resistant nickel alloy that contains other chemical elements such as chromium and molybdenum. This material has high temperature resistance and excellent corrosion resistance. Hastelloy C276 is one of the Hastelloy grades used in the oil and gas industry.

Hastelloy C22, also known as alloy C22, is a versatile austenitic nickel-chromium-molybdenum-tungsten alloy with enhanced resistance to pitting, crevice corrosion and stress corrosion cracking.s. It is available in the form of plates,
sheets, strips, billets, bars, wires, pipes, tubes, and covered electrodes.

The high nickel and molybdenum contents make the nickel steel alloy especially resistant to pitting and crevice corrosion in reducing environments while chromium conveys resistance to oxidizing media.

The B2 forged fitting is the cornerstone of a strong comic, and the composition of Hastelloy leverages it to have the necessary strength and quality standards to help it withstand a lot of stress for years to come.

ASTM B619 UNS N10276 Alloy C276 Tube covers 2 classes under this specification. In class 1, the Hastelloy C276 Tube is furnished in an as welded and solution annealed condition or these tubes could be welded along with being sized and solution annealed.
