Simbi dzisina ngura isimbi dzine alloy yakawanda. Simbi idzi dzinowanikwa mumapoka mana anosanganisira martensitic, austenitic, ferritic uye precipitation-hardened steels. Mapoka aya anoumbwa zvichibva pachimiro che crystalline chesimbi dzisina ngura.
Simbi dzisina ngura dzine huwandu hwakawanda hwechromium kana tichienzanisa nedzimwe simbi saka dzine simba rakanaka rekudzivirira ngura. Simbi zhinji dzisina ngura dzinenge 10% yechromium.
Simbi isina ngura yeGiredhi 2205 isimbi isina ngura mbiri ine dhizaini inoita kuti ikwanise kubatanidza kusimba kuri nani pakudonha, simba guru, ngura ine stress, ngura ine mitswe uye kutsemuka. Simbi isina ngura yeGiredhi 2205 inodzivirira ngura ine sulfide uye chloride.
Pepa redata rinotevera rinopa ruzivo rwesimbi isingasvibi yemhando ye2205.

Kugadzira uye Kurapa Kupisa
Kunyungudutsa
Simbi isingasvibi yeGiredhi 2205 inonamirwa pa1020-1070°C (1868-1958°F) yobva yadzimwa mvura.
Kushanda Kunopisa
Simbi isingatsvi yeGiredhi 2205 inopiswa pakupisa kuri pakati pe954-1149°C (1750-2100°F). Kupisa kwesimbi iyi isingatsvi yeGiredhi pasi pekupisa kwemukamuri kunokurudzirwa pese pazvinogoneka.
Kushongedza
Nzira dzekuwedera dzinokurudzirwa pasimbi isingatsvi yegiredhi 2205 dzinosanganisira SMAW, MIG, TIG uye nzira dzemagetsi dzakavharirwa nemaoko. Munguva yekuwedera, zvinhu zvinofanira kutonhodzwa pasi pe149°C (300°F) pakati pemapasi uye kupisa kwechinhu chekuwedera kunofanira kudzivirirwa. Zvinopinda mukupisa kushoma zvinofanirwa kushandiswa pakuwedera simbi isingatsvi yegiredhi 2205.
Kugadzira
Simbi isina ngura yeGiredhi 2205 inonetsa kugadzirwa nekuda kwesimba rayo guru uye kumhanya kwayo kwekuomesa.
Kugona kuchinjika
Simbi isingasvibi yeGiredhi 2205 inogona kugadzirwa nekabhoni kana maturusi ekumhanya zvakanyanya. Kumhanya kwacho kunoderedzwa neinenge 20% kana maturusi ekabhoni achishandiswa.
Mashandisirwo
