Inconel Alloy 625 Seamless Tubes Metallurgical structure

Inconel 625 Tubing Inonel 625 Pipe is face-centered cubic lattice structure. Dissolve out the carbon granule and instability quaternary phase, then change it to stability Ni3 (Nb,Ti) trimetric lattice around 650℃ after a long time heat preservation. nickel-chromium content will strength the mechanical performance in the state solution while suppress the plasticity

Inconel Alloy 625 Seamless Tubes Corrosion resistance

625 own a very good corrosion resistance in many media, especially with excellent resistance to pitting, crevice corrosion, intercrystalline corrosion, and erode in oxide, also good resistance to inorganic acid corrosion, such as nitric acid, phosphoric acid, sulfuric acid and hydrochloric acid. 625 can resist the alkali and organic acid corrosion in the oxidation and reduction environment. Effect resists the chloride reduction stress corrosion cracking. Normally no corrosion in the sea-water and industry environments since high corrosion resistance to the sea-water and salting liquid,as well as in high temperature, without sensitivity during welding. 625 have the resistance to oxidation and carbonizing in the static and cycle environments, also hacve the resistance the chlorine corrosion.

Inconel 625 Seamless Tubes Application

Soften annealing low carbon alloy 625 widely used in the chemical process industry, good corrosion resistance and high strength made it an good choice for structural parts. 625 have application in sea-water for local mechanical stress attach.

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.
