Product Description 1. MaterialSteel GradeINCONEL 625 ( UNS N06625)Production ProcessAvailable in cold rolled and cold drawnStandardASME SB444 Standard Specification for Nickel-Chromium-Molybdenum-Columbium Alloys (UNS N06625 and UNS N06852) and Nickel-Chromium-Molybdenum-Silicon Alloy (UNS N06219) Pipe and Tube2. Diameter of Stainless PipeW.T1mm-10mmDiameter20mm thru 219mmLength2m-12m, or customer required4.Characteristic1. Excellent corrosion resistance of different kinds of media in both oxidation and reduction environments.2. Excellent resistance of pitting and crevice corrosion, and won't happen stress corrosion cracking because of chloride.3.Excellent resistance of the inorganic acid corrosion performance, phosphoric acid, sulfuric acid, hydrochloric acid and the mixture of sulfuric acid and hydrochloric acid.4. Excellent corrosion resistance of different kinds of inorganic acid mixture performance.5. Good corrosion resistance of a variety of concentrations of hydrochloric acid when the temperature up to 40oC6. Good machining and welding, no weld cracking sensitivity.7. Have pressure vessel authentication for the wall temperature between -196-450oC8. Apply for the highest standard lever VII of acidic environment by the NACE MR-01-75 authorized.5. Metallurgical StructureInconel 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 650oC after a long time heat preservation. nickel-chromium content will strength the mechanical performance in the state solution while suppress the plasticity6.Corrosion Resistance625 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, 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.7.Fabrication with Inconel 625Alloy 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.8. Packing*All of our nickel alloy seamless pipes and tubes are packaged according to international standards to prevent any possible damage or loss. By default, we will use thick woven plastic bags to bundle the finished pipes together in batches.For some special pipes and tubes that are vulnerable to dirt, scratches, stress, or rough handling, we will suggest using wooden cases for protection. Please note that wooden cases may incur extra costs not only for the case itself but also for increased freight costs, especially when using air transportation. To enhance customer experience, we also provide dedicated packaging according to your specific requirements."9.
