Difference between Inconel 600 and Inconel 625 Round Bars

Inconel 600 Round Bars are nickel-chromium alloy bars used for applications that require corrosion and high-temperature resistance. Inconel 600 Round Bars are designed for service temperatures from cryogenic to elevated temperatures in the range of 2000 degree F. Inconel 600 Bars are non-magnetic, have excellent mechanical properties, and present the desirable combination of high strength and good weldability under a wide range of temperatures. The high nickel content in Inconel 600 Bars enables it to retain considerable resistance under reducing conditions, makes it resistant to corrosion by a number of organic and inorganic compounds, gives it excellent chloride-ion stress-corrosion cracking resistance and also provides outstanding resistance to alkaline solutions. Typical applications of this UNS N06600 Round Bars include the chemical, pulp and paper, aerospace, nuclear engineering, and heat-treating industries.

Characteristics

  • Resistant to a large vary of corrosive media.
  • Virtually resistant to chlorine ion stress corrosion cracking
  • Non-magnetic
  • Excellent mechanical properties
  • High strength and good weldability under a large vary of temperatures

Applications

  • Chemical industry
  • Aerospace
  • Heat treating industry
  • Pulp and paper industry
  • Food processing
  • Nuclear Engineering
  • Gas turbine components

Fabrication

Alloy 600 Round Bars can be both hot formed and cold-formed using typical processes. Hot-working should be performed between 1600 degrees F and 2250 degrees F avoiding any work between1200-1600 degrees F because the ductility decreases in this temperature range. Welding Alloy 600 Bars can be achieved via shielded metal-arc welding, TIG, and MIG.

Overview

Inconel 625 Round Bars are corrosion and oxidation resistant nickel alloy bars that are used both for its high strength and outstanding aqueous corrosion resistance. Its excellent strength and toughness are due to the addition of niobium which acts with the molybdenum to stiffen the alloy’s matrix. Alloy 625 bars have excellent fatigue strength and stress-corrosion cracking resistance to chloride ions and excellent weldability and is frequently used to weld AL-6XN. They resist a wide range of severely corrosive environments and are especially resistant to pitting and crevice corrosion. Some typical applications Inconel 625 Bars are used in are chemical processing, aerospace and marine engineering, pollution-control equipment, and nuclear reactors.

Characteristics

  • High creep-rupture strength
  • Oxidation resistant to 1800 degree F
  • Seawater pitting and crevice corrosion resistant
  • Immune to chloride ion stress corrosion cracking
  • Non-magnetic

Applications

  • Aircraft ducting systems
  • Aerospace
  • Jet engine exhaust systems
  • Engine thrust-reverser systems
  • Specialized seawater equipment
  • Chemical process equipment

Fabrication

Inconel 625 Bars have excellent forming and welding characteristics. It may be forged or hot worked providing temperature is maintained in the range of about 1800-2150 degree F. Ideally, to control grain size, finish hot working operations should be performed at the lower end of the temperature range. Because of its good ductility, alloy 625 round bars are also readily formed by cold working. These nickel alloy 625 round bars can be welded by both manual and automatic welding methods, including gas tungsten arc, gas metal arc, electron beam, and resistance welding. It exhibits good restraint welding characteristics.
