Intangiriro
Ibyuma bidafite ingese ni ibyuma-binini cyane.Ibyo byuma biboneka mumatsinda ane arimo martensitike, austenitis, ferritic hamwe nimvura ikomera.Aya matsinda yashizweho ashingiye kumiterere ya kristaline yibyuma bitagira umwanda.
Ibyuma bitagira umuyonga birimo chromium nyinshi ugereranije nandi mashanyarazi bityo bikarwanya ruswa.Ibyinshi mu byuma bitagira umwanda birimo hafi 10% ya chromium.
Icyiciro cya 2205 ibyuma bitagira umuyonga nicyuma cya duplex idafite ibyuma bishushanya bifasha guhuza imbaraga zirwanya imyanda, imbaraga nyinshi, kwangirika kwangirika, kwangirika kwimitsi no guturika.Icyiciro cya 2205 ibyuma bitagira umwanda birwanya sulfide ihungabana hamwe nibidukikije bya chloride.
Datasheet ikurikira itanga incamake yicyiciro cya 2205 ibyuma bitagira umwanda.

Ibindi
Ibikoresho bihwanye nicyiciro 2205 ibyuma bidafite ingese ni:
- ASTM A182 Icyiciro F51
- ASTM A240
- ASTM A789
- ASTM A790
- DIN 1.4462
Guhimba no kuvura ubushyuhe
Annealing
Icyiciro cya 2205 ibyuma bitagira umwanda bifatirwa kuri 1020-1070 ° C (1868-1958 ° F) hanyuma amazi akazima.
Gukora Bishyushye
Icyiciro cya 2205 ibyuma bidafite ingese birashyushye bikozwe mubushyuhe bwa 954-1149 ° C (1750-2100 ° F).Gukora bishyushye muriki cyiciro ibyuma bitagira ibyuma munsi yubushyuhe bwicyumba birasabwa igihe cyose bishoboka.
Gusudira
Uburyo bwo gusudira busabwa icyiciro cya 2205 ibyuma bitagira umuyonga birimo SMAW, MIG, TIG hamwe nuburyo bwa electrode bukoreshwa.Mugihe cyo gusudira, ibikoresho bigomba gukonjeshwa munsi ya 149 ° C (300 ° F) hagati yinzira no gushyushya igice cyo gusudira.Ubushyuhe buke bugomba gukoreshwa mu gusudira icyiciro 2205 ibyuma bitagira umwanda.
Gushiraho
Icyiciro cya 2205 ibyuma bitagira umuyonga biragoye kubikora kubera imbaraga nyinshi nigipimo cyo gukomera.
Imashini
Icyiciro cya 2205 ibyuma bidafite ingese birashobora gukoreshwa hamwe na karbide cyangwa ibikoresho byihuta.Umuvuduko ugabanukaho 20% mugihe hakoreshejwe ibikoresho bya karbide.
Porogaramu
Icyiciro cya 2205 ibyuma bidafite ingese bikoreshwa mubikurikira:
