625 alloy

alloy 625 = UNS N06625, is an alloy with high resistance and ductility at lowest temperatures and up to 1100° C. Techalloy 625 is not magnetic and apart from its high oxidation resistance it is also resistant against many media. High resistance against stress corrosion cracking, pitting and crevice corrosion is also a main characteristic of Techalloy 625.



Specification:
Seamless Tubes: ASTM-B-444
Welded Tubes: ASTM-B-704/705
Plates/ Sheets: ASTM-B-443
Bars: ASTM-B-446
Fittings: ASTM-B-366
Flange: ASTM-B-564
Specific weight: 8,44 kg/dm 3
Melting range: 1290 - 1350° C


Welding methods: Arc welding, TIG,MIG, UP and autogenous welding (details on request)
Product forms: Tubes and pipes, plates and sheets, bars, wire, fittings and flanges Range of application: fuel and hydraulic line tubing, thrust-reverser systems, spray bars, bellows, thrust-chamber tubing for rocket motors, reaction vessels, distillation columns, heat exchanger tubes, valves etc.
