Intshayelelo
Iintsimbi ezingagqwaliyo ziintsimbi ezine-alloy ephezulu. Ezi ntsimbi zifumaneka kumaqela amane aquka iintsimbi ze-martensitic, i-austenitic, i-ferritic kunye ne-precipitation-hardened. La maqela enziwe ngokusekelwe kwisakhiwo se-crystalline seentsimbi ezingagqwaliyo.
Iintsimbi ezingenasici ziqulathe inani elikhulu le-chromium xa kuthelekiswa nezinye iintsimbi kwaye ngaloo ndlela zinokumelana nokugqwala okuhle. Uninzi lweentsimbi ezingenasici ziqulathe malunga ne-10% ye-chromium.
Intsimbi engagqwaliyo yeBakala 2205 yintsimbi engagqwaliyo ephindwe kabini enoyilo oluvumela ukudibanisa ukumelana okuphuculweyo nokuqhekeka kwemigodi, amandla aphezulu, ukugqwala koxinzelelo, ukugqwala kwemingxuma kunye nokuqhekeka. Intsimbi engagqwaliyo yeBakala 2205 imelana nokugqwala koxinzelelo lwe-sulfide kunye neendawo ze-chloride.
Iphepha ledatha elilandelayo libonelela ngesishwankathelo sentsimbi engagqwaliyo yebanga lama-2205.

Ezinye iiNgcali
Izinto ezilinganayo nentsimbi engagqwaliyo yebanga lama-2205 zezi:
- Ibanga le-ASTM A182 F51
- I-ASTM A240
- I-ASTM A789
- I-ASTM A790
- I-DIN 1.4462
Ukwenziwa kunye noNyango lobushushu
Ukuqokelela
Intsimbi engagqwaliyo yebanga lama-2205 ifakwa kwi-1020-1070°C (1868-1958°F) ize itshiswe ngamanzi.
Ukusebenza Okushushu
Intsimbi engagqwaliyo yebanga 2205 ishushu kakhulu xa isetyenziswa kubushushu obuyi-954-1149°C (1750-2100°F). Kucetyiswa ukuba le ntsimbi ingagqwaliyo yebanga ishushu xa isetyenziswa kubushushu begumbi nanini na xa kunokwenzeka.
Ukuwelda
Iindlela zokuwelda ezicetyiswayo kwintsimbi engagqwaliyo yebanga lama-2205 ziquka i-SMAW, i-MIG, i-TIG kunye neendlela ze-electrode ezigqunywe ngesandla. Ngexesha lenkqubo yokuwelda, izinto kufuneka zipholiswe ngaphantsi kwe-149°C (300°F) phakathi kokudlula kunye nokufudumeza kwangaphambili kwento yokuwelda kufuneka kuthintelwe. Kufuneka kusetyenziswe izinto ezifakwa kubushushu obuphantsi kwintsimbi engagqwaliyo yebanga lama-2205.
Ukwenziwa
Intsimbi engagqwaliyo yebanga le-2205 kunzima ukuyenza ngenxa yamandla ayo aphezulu kunye nesantya sokuqina komsebenzi.
Ukungakwazi ukusebenza
Intsimbi engagqwaliyo yebanga le-2205 inokusetyenziswa ngomatshini nge-carbide okanye ngesixhobo esikhawulezayo. Isantya sincitshiswa malunga ne-20% xa kusetyenziswa isixhobo se-carbide.
