Intangiriro
Ibyuma bitagira umushongi ni ibyuma bifite aloyi nyinshi. Ibi byuma biboneka mu matsinda ane arimo ibyuma bya martensitic, austenitic, ferritic na precipitated. Aya matsinda ashingwa hashingiwe ku miterere ya crystalline y'ibyuma bitagira umushongi.
Ibyuma bitanduye birimo chromium nyinshi ugereranije n'ibindi byuma bityo bikaba birwanya ingese neza. Ibyuma byinshi bitanduye birimo chromium ingana na 10%.
Icyuma kidasanza cya Grade 2205 ni icyuma kidasanza cya kabiri gifite imiterere ifasha guhuza uburyo bwo kurwanya imyobo, imbaraga nyinshi, ingese, ingese yo mu miyoboro no kwangirika. Icyuma kidasanza cya Grade 2205 kirwanya ingese yo mu miyoboro ya sulfide na chloride.

Izindi Nshingano
Ibikoresho bingana n'icyuma kitagira umugese cyo mu rwego rwa 2205 ni ibi bikurikira:
- ASTM A182 Icyiciro cya F51
- ASTM A240
- ASTM A789
- ASTM A790
- DIN 1.4462
Gukora no Gutunganya Ubushyuhe
Annealing
Icyuma kidafunze cya Grade 2205 gishyirwa ku bushyuhe bwa 1020-1070°C (1868-1958°F) hanyuma amazi agashira.
Gukora Bishyushye
Icyuma kitagira umugese cyo mu rwego rwa 2205 gishyushye mu bushyuhe buri hagati ya 954-1149°C (1750-2100°F). Gushyushya iki cyuma kitagira umugese mu bushyuhe bw'icyumba ni byiza igihe cyose bishoboka.
Gusudira
Uburyo bwo gusudira busabwa ku byuma bitagira umushongi byo mu rwego rwa 2205 birimo SMAW, MIG, TIG n'uburyo bwo gusuka electrode ipfundikiye intoki. Mu gihe cyo gusudira, ibikoresho bigomba gukonjeshwa munsi ya 149°C (300°F) hagati y'inzira no gushyushya igice cyo gusudira bigomba kwirindwa. Hagomba gukoreshwa ubushyuhe buke mu gusudira icyuma kitagira umushongi cyo mu rwego rwa 2205.
Gukora
Icyuma kidasa neza cyo mu rwego rwa 2205 kiragoye kugikora bitewe n'imbaraga zacyo nyinshi n'umuvuduko wo gukomera kw'akazi.
Ubuhanga bwo gukora
Icyuma kitagira umugese cyo mu rwego rwa 2205 gishobora gucukurwa hakoreshejwe karubide cyangwa ibikoresho byihuta cyane. Umuvuduko ugabanukaho hafi 20% iyo hakoreshejwe ibikoresho bya karubide.
Porogaramu
Icyuma kitagira umugese cyo mu rwego rwa 2205 gikoreshwa mu bikorwa bikurikira:
- Akayunguruzo k'imyuka ikoresha amashanyarazi
- Ibigega bya shimi
- Ibikoresho byo guhinduranya ubushyuhe
- Ibice byo gusya aside asetiki
