Ibihimbano by'iki cyiciro nabyo bigira ingaruka ku mbaraga zabyo.Kwunama no gushiraho iki cyiciro bisaba ibikoresho bifite ubushobozi bunini.Guhindagurika kwicyiciro cya 2205 ni munsi yicyiciro cya austenitis;kubwibyo, imitwe ikonje ntabwo ishoboka muriki cyiciro.Kugirango ukore ibikorwa bikonje bikonje kuri iki cyiciro, hagomba gukorwa annealing hagati.
Porogaramu
Bimwe mubikorwa bisanzwe bya duplex ibyuma 2205 byerekanwe hano hepfo:
- Ubushakashatsi bwa peteroli na gaze
- Ibikoresho byo gutunganya
- Gutwara, kubika no gutunganya imiti
- Ibidukikije bya chloride hamwe ninyanja
- Imashini zimpapuro, ibigega byinzoga, pulp hamwe nogusya impapuro
