Usetyenziso lweDuplex Ss 2205
I-2205 insimbi engenasici 4 * 1mm i-capillary coiled tubing
Ezinye zeenkqubo eziqhelekileyo ze-duplex zensimbi engenasici kwibakala 2205 zidweliswe ngezantsi:
- Ukuhlola i-oyile negesi
- Izixhobo zokusebenza
- Uthutho, ukugcinwa, kunye nokulungiswa kweekhemikhali
- I-chloride ephezulu kunye neendawo zaselwandle
- Oomatshini bephepha, iitanki zotywala, i-pulp, i-digesters yamaphepha, njl.
Iimpawu zeDuplex Ss 2205
I-2205 insimbi engenasici 4 * 1mm i-capillary coiled tubing
I-Duplex Stainless Steel 2205 xa kuthelekiswa ne-316L kunye ne-317L i-austenitic stainless steels, i-2205 iphezulu kwi-anti-pitting kunye ne-crevice corrosion resistance.Inokumelana ne-corrosion ephezulu.Xa kuthelekiswa ne-austenite, i-coefficient yokwandisa i-thermal iphantsi, i-thermal conductivity iphezulu.
I-Duplex Stainless Steel 2205 inamandla aphindwe kabini e-austenitic stainless steel, evumela abaqulunqi ukuba banciphise ubunzima babo xa kuthelekiswa ne-316L kunye ne-317L.I-alloy ye-2205 ifanelekile ngokukodwa ukusetyenziswa kwi- -50 ° F / + 600 ° F uluhlu lobushushu kwaye ingasetyenziselwa amaqondo okushisa aphantsi phantsi kwezithintelo ezinzima (ingakumbi kulwakhiwo oludibeneyo).
Uxhathiso lwe-corrosion ye-2205 Duplex Stainless Steel
I-2205 insimbi engenasici 4 * 1mm i-capillary coiled tubing
- I-corrosion efanayo, Ukuxhatshazwa kwe-corrosion ye-duplex stainless steel 2205 iphezulu kune-316L kunye ne-317L kwiindawo ezininzi ngenxa yomxholo we-chromium (22%), i-molybdenum (3%), kunye nomxholo we-nitrogen (0.18%).
I-anti-corrosion yendawo, Umxholo we-chromium, i-molybdenum, kunye ne-nitrogen kwi-duplex stainless steel 2205 yenza ukuba ixhathise kakhulu kwi-pitting kunye ne-crevice corrosion kwi-oxidizing kunye ne-acidic solutions. - I-Anti-stress corrosion, I-2205 isakhiwo se-duplex yensimbi engenasici inceda ukuphucula ukuchasana noxinzelelo lwe-corrosion cracking yensimbi engenasici.Kwiqondo lokushisa elithile, phantsi kweemeko zoxinzelelo, i-oksijini, kunye nekloridi, i-chloride stress corrosion ivela kwi-austenitic stainless steel.Njengoko le miqathango ingalawulwa ngokulula, ukusetyenziswa kwe-304L, i-316L, kunye ne-317L ilinganiselwe kule nkalo.
- Ukudinwa kwe-Anti-corrosion, i-Dual-phase steel 2205 amandla aphezulu kunye nokumelana nokugqwala kumandla aphezulu okumelana nokudinwa.Izixhobo zokucubungula zithinteka kwiindawo ezinobungozi kunye nemijikelezo yokulayisha, kunye ne-duplex stainless steel stainless 2205 iimpawu zifaneleke kakuhle kwizicelo ezinjalo.
I-Metallography malunga ne-Duplex Ss 2205 uns s31803
Ukwakhiwa kweekhemikhali ze-2205 duplex steel kunika i-microstructure efunwayo ye-50 ϫ / 50 emva kwe-1900 / 1922 ° F (1040 ° C / 1080 ° C) isisombululo esiluqilima.Ukuba ubushushu bonyango lobushushu bungaphezulu kwe-2000 ° F, kunokukhokelela ekwandeni kokwakheka kwe-ferrite.Njengezinye iintsimbi eziphindwe kabini, iialloyi ezingama-2205 zisesichengeni semvula yesigaba se-intermetallic.
Isigaba se-intermetallic sihamba phakathi kwe-1300 ° F kunye ne-1800 ° F kwaye iyancipha ngokukhawuleza kwi-1600 ° F. Ngoko ke, kufuneka sivavanye i-2205, ukuqinisekisa ukuba akukho sigaba se-intermetallic, i-reference reference ASTM A 923.
