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.

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 G-30 is an improved version of nickel-chromium-iron-molybdenum-copper alloy G-3. With higher chromium, added cobalt and tungsten, the G-30 shows superior corrosion resistance over most other nickel and iron based alloys in commercial phosphoric acids as well as complex environments containing highly oxidizing acids. The resistance of the alloy to the formation of grain boundary precipitates in the heat-affected zone makes it suitable for use in most chemical process applications in the as-welded condition.

The Hastelloy C276 round tube is manufactured from a high temperature heat resistant alloy, which contributes to its widespread use in the power industry. Whereas, Hastelloy C276 pipe exhibits outstanding properties such as high wear resistance, corrosion resistance and longer service life due to the raw materials used in its processing.

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.

HASTELLOY C-4 alloy (UNS N06455) is the most (microstructurally) stable of the widely
used nickel-chromium-molybdenum materials, which are well known for their resistance
to many aggressive chemicals, in particular hydrochloric acid, sulfuric acid, and chlorides. This alloy resists the formation of grain-boundary precipitates in the weld heat-affected zone, thus making it suitable for most chemical process applications in the as-welded condition.

Other corrosives Hastelloy C-22 has resistance to are oxidizing acid chlorides, wet chlorine, formic and acetic acids, ferric and cupric chlorides, sea water, brine and many mixed or contaminated chemical solutions, both organic and inorganic.

They have good creep and oxidation resistance. Strengthening of super alloys is performed by solid-solution hardening, work hardening, and precipitation hardening methods.

Each of them have structural differences. These flanges are made up of a nickel, chromium, molybdenum alloy that has 50% nickel 14% chromium, 15% molybdenum and carbon, manganese, silicon, sulfur, cobalt, iron and phosphorus in the composition.

Hastelloy X is a nickel-based superalloy ideal for gas turbine engine, aircraft, industrial furnace, and chemical processing applications.

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

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.

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

Hastelloy B3 pipe is significantly resistant to corrosion resistance at reducing atmosphere. Hastelloy B2 pipes are having excellent resistance to non-oxidizing acid and sulphuric acid.

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.

Alloy C-276 is also defined as Alloy C276, Inconel C 276 or Hastelloy C, which is a superalloy with a perfect combination of molybdenum, nickel and chromium. Tungsten is added, which is designed to provide excellent corrosion resistance even in harsh environments.

c276 is highly resistant to most chemicals and corrosive environments. The anti-corrosion and anti-oxidative properties come from the composition of chromium and molybdenum.

It is well known that Hastelloy c22/C276 fasteners have good dimensional accuracy, corrosion resistance, durability, high durability, high flexibility, strong structure, high tensile strength and other characteristics. In addition, fasteners are resistant to wear in high temperature atmospheres and corrosive environments. Some of the environments in which these fasteners exhibit resistance are oxidizing media, reducing media, chloride environments, and sulfur environments. They are resistant to attack by chemicals such as nitric acid, chlorine, sulfur, acetic acid, organic, inorganic, phosphorus, etc.

Hastelloy UNS N10276 sheets that are ideal for various sectors and meet our clients’ needs. We manufacture ASTM B575 Hastelloy C-276 plates in a variety of sizes and specifications.

HASTELLOY(r) C276 can be formed by cold working using conventional techniques.

Hastelloy G30 is a nickel-based alloy with a high chromium content that provides superior corrosion resistance to commercial phosphoric acid and many highly oxidizing acid media.

Cold bending methods often rely on sheer physical force to help bring the pipe to its final shape while hot bending methods use careful heating to reduce the force required.

The applications range from chemical, petrochemical, power generation and OEM manufacturing industry as well other applications where vibration, high pressure or extremely corrosive conditions exist.

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

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.

The pipes are phosphoric acid, acetic and formic acid resistant. Also, it to various temperature and concentrations is hydrochloric acid resistance.

This nickel alloy also offers optimum resistance to environments where reducing and oxidizing conditions are encountered in process streams. This is beneficial in multi- purpose plants where such ¡°upset¡± conditions occur frequently.

These flanges demonstrate outstanding toughness and hardness. Thus it exhibits superior ductility after prolonged exposure at a temperature of 650, 760, 870 degree C.

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.

Hastelloy X is a nickel-chromium-iron-molybdenum alloy. It has excellent oxidation resistance, workability and high temperature strength. It also exhibits good resistance to stress corrosion cracking in petrochemical applications. It shows very good ductility after prolonged exposure at 1200 to 1600 degrees Fahrenheit. It has excellent forming and welding properties, and is widely used in furnaces for aircraft and gas turbines.

We are a manufacturer, trader, stockist, supplier, and exporter of ASTM B564 Hastelloy B2 Flanges that are known as ‘High-performance Flanges’ for their Nickel-Molybdenum combination, alloyed with a lower content of Iron, Silicon and Carbon, which makes them adept in administering control over the conveyance of reducing acids at higher temperatures.

C22 is typically provided in the annealed condition with a minimum yield strength of 45 ksi. However, C22 can be cold worked to higher strength levels.
