INCONEL® chisanganiswa 690(UNS N06690/W. Nr. 2.4642) ndeyepamusoro-chromium nickel alloy ine kupikisa kwakanyanya kune yakawanda inopisa aqueous media uye yakakwirira-tembiricha yemhepo.Pamusoro pekupokana kwayo kwekuora, alloy 690 ine simba rakawanda, yakanaka metallurgical kugadzikana, uye yakanaka yekugadzira maitiro.
Iyo Inconel Alloy 690 Pipe & Tube inopa hukuru hwekupokana kune hwakasiyana-siyana hwekuora midhiya senge chloride ion kusagadzikana kupaza uye inopa yakanyanya tembiricha kuita uye inokonzera kuramba kune oxidation.
Inconel Alloy 690 Pipe & Tube is an austenite nickel-chromium-based superalloys grade chubhu, tubing, pombi & tubular zvigadzirwa kuOiri NeGasi, Nuclear Uye Simba, Simba Generation, Aerospace, Process Industries & Refining, General Industrial, Chemical Process, Medical , Kuchena Kwepamusoro uye Kuita Kwepamusoro.Inconel Alloy 690 Pipe & Tube yakanyatsokodzera kushanda munzvimbo dzakanyanyisa pasi pekumanikidzwa uye kupisa.

Kupisa uye Pickling
Kufanana nemamwe nickel alloys, alloy 690 inofanira kuva yakachena isati yapisa uye inofanira kupiswa mumhepo yakaderera-sarufa.Furnace atmospheres yekudziya yakavhurika inofanirawo kuderedzwa zvishoma kudzivirira kuwandisa oxidation yezvinhu.
INCONEL alloy 690 is solid-solution alloy uye haina kuomeswa nekupisa kurapwa.Iyo alloy inowanzo shandiswa mune annealed mamiriro.
Kuumba
Tembiricha yemhando yekupisa inorema kuumbwa kweINCONEL alloy 690 ndeye 1900 kusvika 2250°F (1040 kusvika 1230°C).Kugadzira chiedza kunogona kuitwa pakupisa kusvika pa1600°F (870°C).
Microstructure
INCONEL alloy 690 is an austenitic, solid-solution alloy ine yakakwira dhigirii yekugadzikana kwemetallurgical.Iyo alloy ine yakaderera solubility yekabhoni, uye microstructure yayo inowanzo ine carbides.Iyo huru carbide iripo mune alloy ndeye M23C6;kuwanda kwechikamu kunosiyana nekabhoni yemukati uye kupisa kuratidzwa kwezvinhu.Zvimwe zvikamu zvinowanzovepo titanium nitrides uye carbonitrides.Hapana ebrittling intermetallic phases senge sigma phase yakaonekwa mune alloy 690.
