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

Fabrication with Inconel 625
Alloy 625 has excellent forming and welding characteristics. It may be forged or hot worked providing temperature is maintained in the range of about 1800-2150° 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 is also readily formed by cold working. However, the alloy does work-harden rapidly so intermediate annealing treatments may be needed for complex component forming operations. In order to restore the best balance of properties, all hot or cold worked parts should be annealed and rapidly cooled. This nickel alloy 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.
