Hastelloy Classification:

  • Hastelloy C276 is a kind of nickel-molybdenum-chromium-iron-tungsten nickel-based alloy. It is the most resistant one of modern metal materials. It is considered as a all-potent corrosion-resistant alloy.Wet chlorine resistance, all kinds of oxidation chloride, chloride salt solution, sulfuric acid and oxidized salt, in low temperature and medium temperature hydrochloric acid, it has strong corrosion resistance.

Hastelloy C276 Application: Boiled and bleaching containers in Pulp and paper industries; Washing tower, reheater, wet fan in FGD system; Equipment and components operating in an acidic gas environment; Reactor for acetic acid and acid products; Sulphate condenser; Production and processing of impure phosphoric acid etc.

  • Hastelloy C2000 is a new type of Ni-Cr-Mo alloy, which improves the chromium content and adds copper, greatly improves the oxidation  resistance and corrosion capacity of the alloy. It is a good alloy with H2SO4 corrosion resistance in this series, therefore, it is feasible to use this alloy in the H2SO4 environment. It stands up to oxidizing and reducing environments and inhibits localized corrosion. Corrosion

resistance: including Sulfate, hydrochloride, hydrofluoric acid, phosphate organic acid, chloride, alkali metal, spot corrosion, crevice corrosion stress and corrosion cracking.  


Hastelloy C2000 Application: -Chemical process industry reactors, heat exchangers, columns, and piping Pharmaceutical industry reactors and dryers; - Flue gas desulfurization systems.

  • Hastelloy C22 is based on the basis of C276, among the alloy chromium content is increased and molybdenum and tungsten are reduced, in which the carbon and silicon content are very low, which is the strong oxidation medium corrosion of C4 and C276. Although the corrosion resistance of the oxidation medium is improved, the spot corrosion resistance and gap corrosion resistance are not significantly improved. Excellent stress and corrosion cracking resistance and good local  resistance.

Hastelloy C22 Application: Chlorination systems; Flue gas scrubbers; Outlet ducting and stack liners for power plants, pulp and paper bleach plants, sulfur dioxide scrubbers, and weld overlay of less corrosion resistant metal; Acid production and pickling systems.

  • Hastelloy G30 is One of the few brands whose chromium content in molybdenum copper alloy is more than 30%, it has strong corrosion resistance in H2SO4, HNO3 and other solutions due to the compound effect of components. Because of the chromium amount greater than 30% and very low carbon amount, and the sufficient addition of niobium, the alloy has good thermal stability and good sensitivity to intercrystalline corrosion resistance. It has good corrosion resistance to sulfuric acid, and has better corrosion resistance to many mixed acid (such as nitric acid and hydrochloric acid) and highly oxidizing acids in other complex environments.

Hastelloy G30 Application: Phosphoric acid equipment;Sulphuric acid equipment; Nitric acid equipment; Nuclear fuel reprocessing; Nuclear waste disposal; Pickling operations; Petrochemical products; Fertilizer production; Pesticide production; Gold extraction etc.

  • Hastelloy X is a nickel-chromium-molybdenum alloy supplemented with cobalt and tungsten providing outstanding performance at elevated temperatures, as well as being formable and weldable. Hastelloy X has excellent oxidation resistance at high temperatures up to 1200℃and can also be applied to a neutral and reducing atmosphere, meanwhile, resist the carbonization and nitride atmosphere. It has moderate holding-long and creep strength at high temperature of 900℃. With good oxidation resistance and corrosion resistance, good cold and hot processing formability and welding performance, it is suitable for the production of long-term use of aviation engine combustion chamber below 900℃, as well as the working temperature up to 1080℃ short use of high temperature parts.

Hastelloy X Application: widely used in civil industry and aviation engine, gas turbines(Jet engine combustion chambers, rectifier, structural cover); petrochemical furnace; industrial furnaces; turbine exhaust components; Aircraft cabin heaters;support rollers, radiant tube etc.

  • Haynes 188 is a cobalt-based special alloy with unique high temperature strength and oxidation resistance. It is remfully malleable after extended exposure to a temperature range of 1400 – 1600°F. Compared with the cobalt-based alloy and nickel-based alloy, it is with inherent high temperature creep properties. 14% tungsten was added for solid solution strengthening and followed by M6C and M23C6 carbide. It is easy to process. Manual and automatic welding are applicable, welding methods including electron beam, tungsten pole gas argon arc welding and resistance welding.  

Haynes 188 includes cobalt, nickel, chromium and tungsten, its high temperature strength is very good, it was placed at 1095°C for a long time, still with good oxidation resistance, and can resist the thermal corrosion of sulfur sediment effectively. Haynes 188 can be processed by the traditional process, and can also be used for casting parts. It has very good forming and machining characteristics. It can be forged, or hot worked. Hot-work requires keeping the workpiece at 1175°C long enough to ensure that the entire workpiece reaches this temperature. Because the material is very ductile, it can be processed in cold work. Because haynes 188 is of rapid cold hardening, it needs annealing several times when processing complex parts. Both hot and cold processed parts need to be annealed treatment and quickly cooled so as to restore the performance of the material.

Haynes 188 Application: Aero engine combustion chamber flame cylinder, guide blade and other high temperature components; gas turbine and missile, such as combustion chamber, tail nozzle and heat exchanger in the nuclear energy industry.
