Intshayelelo
Iintsimbi ezingenasici ziziintsimbi eziphezulu.Ezi ntsimbi zifumaneka kumaqela amane abandakanya i-martensitic, i-austenitic, i-ferritic kunye ne-precipitation-hardened steels.La maqela akhiwe ngokusekelwe kwisakhiwo se-crystalline yeentsimbi ezingenasici.
Iintsimbi ezingenastainless zinezixa ezikhulu zechromium xa kuthelekiswa nezinye iintsimbi kwaye ke zinokumelana nokudumba okulungileyo.Uninzi lweentsimbi ezingenasici ziqulethe malunga ne-10% yechromium.
IBanga le-2205 insimbi engenasici yintsimbi ephindwe kabini, idizayini yayo ivumela ukudibanisa ukuchasana okuphuculweyo kwi-pitting, amandla aphezulu, ukubola koxinzelelo, ukubola kunye nokuqhekeka.IBanga le-2205 insimbi engenasici ixhathisa i-sulfide stress corrosion kunye ne-chloride environments.
Le datha ilandelayo ibonelela ngesishwankathelo sebakala lama-2205 ensimbi engenasici.

Ezinye izibizo
Izinto ezilinganayo kwibakala 2205 intsimbi engatyiwa zezi:
- I-ASTM A182 iBanga le-F51
- I-ASTM A240
- I-ASTM A789
- I-ASTM A790
- I-DIN 1.4462
Ukwenziwa kunye noNyango loBushushu
Ukuhlaziya
I-Grade 2205 insimbi engenasici ifakwe kwi-1020-1070 ° C (1868-1958 ° F) kwaye emva koko kucinywe amanzi.
Ukusebenza okushushu
IBanga le-2205 insimbi engenasici ishushu isebenze kwiqondo lokushisa le-954-1149 ° C (1750-2100 ° F).Ukusebenza okushushu kweli nqanaba lentsimbi engenasici phantsi kobushushu begumbi kuyacetyiswa nanini na xa kunokwenzeka.
Ukuwelda
Iindlela ze-welding ezicetyiswayo kwibakala le-2205 insimbi engenasici ziquka i-SMAW, i-MIG, i-TIG kunye neendlela ezifakwe kwi-electrode manual.Ngethuba lenkqubo ye-welding, izinto eziphathekayo kufuneka zipholile ngaphantsi kwe-149 ° C (300 ° F) phakathi kokudlula kunye nokufudumala kweqhekeza le-weld kufuneka kugwenywe.Ukushisa okuphantsi kufuneka kusetyenziswe kwi-welding grade 2205 yensimbi engenasici.
Ukubumba
IBanga le-2205 insimbi engenasici inzima ukwenza ngenxa yamandla ayo aphezulu kunye nesantya sokuqina komsebenzi.
Ubuchule
IBanga le-2205 insimbi engenasici inokwenziwa ngoomatshini kunye ne-carbide okanye i-high speed tooling.Isantya sincitshiswa malunga ne-20% xa kusetyenziswa i-carbide tooling.
Usetyenziso
IBakala 2205 intsimbi engenastainless isetyenziswa kwezi zicelo zilandelayo:
- Izihluzi zegesi yomkhuhlane
- Amatanki emichiza
- Izitshintshi zobushushu
