Inconel 625 Alloy




The offered Inconel 625 Alloy is widely demanded due its strength, excellent structure, and outstanding corrosion resistance. Its capacity to withstand a wide range of temperatures and pressures makes it one of the top choices of the client. They are used in furnace hardware, gas turbine engine ducting and special sea water applications. They are designed to perfection and are available at nominal rates.

 

Details :

  • Inconel® nickel chromium alloy 625 is used for its high strength, excellent fabricability (including joining), and outstanding corrosion resistance. Service temperatures range from cryogenic to 1800°F.
  • Strength of Inconel® alloy 625 is derived from the stiffening effect with molybdenum and columbium on its nickel-chromium matrix, thus hardening treatments are not required. This combination of chemical elements also is responsible for superior resistance to a wide range of corrosive environments of unusual severity as well as to high-temperature effects such as oxidation and carburization.
  • The inconel 625 versatile and outstanding corrosion resistance under a wide range of temperatures and pressures is a primary reason for its wide acceptance in the chemical processing field. Because of its ease of fabrication, it is made into a variety of element and component for plant equipment. Its high strength enables it be used, for example, in thinner-walled vessels or tubing than possible with other materials, thus improving heat transfer and saving weight. Some applications requiring the combination of corrosion resistance and strength offered by Inconel® alloy 625 are tubing, reaction vessels, distillation columns, heat exchangers, transfer piping and valves.
  • Inconel ® 625 is a nonmagnetic, corrosion and oxidation resistant, nickel-base alloy. It has high strength and toughness in the temperature range cryogenic to 2000°F (1093°C) which is derived largely from the solid solution effects of the refractory metals, columbium and molybdenum, in a nickel-chromium matrix. Alloy 625 has excellent fatigue strength and stress- corrosion cracking resistance to chloride ions.
  • Typical applications for Alloy 625 have included heat shields, furnace hardware, gas turbine engine ducting, combustion liners and spray bars, chemical plant hardware and special seawater applications.
  • Dinkar Alloys. is one of the well known and leading suppliers, manufacturers and exporters of quality Inconel 625 in different forms.
