Simbi isina ngura yeGiredhi 3CR12 imhando yakaderera yesimbi isina ngura ine chromium yakagadzirwa nekushandura hunhu hwesimbi yeGiredhi 409. Inodzivirira ngura uye kusakara kwemvura. Pakutanga yakagadzirwa neColumbus Stainless Company pasi pechiratidzo chakanyoreswa che "3CR12". Mamwe mazita egiredhi iri anosanganisira UNS S40977/S41003 uye 1.4003.
Mamwe mazita akaenzana nemagiredhi e3CR12 anosanganisira magiredhi eASME SA240, magiredhi eASTM A240/A240M, uye EN 10088.2. Zvisinei, EN 10028.7 inosanganisirawo kirasi 1.4003, iyo inoumba simbi isingasvibiswi inoshandiswa pakumanikidza.

Zviri pamusoro apa kungoenzanisa zvinhu zvisina kunyatsojeka. Tafura iyi yakagadzirirwa kupa kuenzanisa kwezvinhu zvakafanana pakushanda, uye zvirevo hazvisi pamutemo. Zvirevo zvepakutanga zvinogona kusimbiswa kana zvichidikanwa zvakaenzana.
Simbi isingatsvi yeGiredhi 3CR12 inogona kushandiswa mukushandiswa uko simbi yealuminium, galvanized kana kabhoni isingapi mhedzisiro yakanaka nekuda kwekusagona kwayo kusimba kweasidhi nemabhesi, pamwe nekutsemuka kunokonzerwa nekuora kwechloride. Zvisinei, kusiyana neGiredhi 304, Giredhi 3CR12 ine kusakwanisa kwakaderera kutsvinda nekuora kwegomba kana paine machloride.
Mumamiriro ekunze, giredhi re3CR12 rave nekutsungirira kwakanaka kwemvura nemachloride, sezvo ngura yehuwandu hwechloride ichideredzwa nemaion enitrate nesulfate. Chimwe chezvinhu zvikuru zvakashata zvegiredhi re3CR12 ndechekuti pamusoro pechinhu chacho pane ngura zvishoma kana chakaiswa munzvimbo chero ipi zvayo. Ndicho chikonzero nei chinhu chacho chakaganhurirwa pakushongedza.
Simbi isingatsvi yemhando ye3CR12 inoratidza kusvibiswa kwemhepo pakati pe600 ne750°C kana paine mhepo uye pakati pe450 ne600°C kana paine kumanikidzwa. Chinhu chacho chinopera simba kana chikagara kwenguva refu chichishandiswa pakupisa kuri pakati pe450 ne550°C. Zvisinei, chinhu ichi hachirasikirwe nekusagadzikana kwacho panguva yekupisa uku.
Simbi isingatsvi yeGiredhi 3CR12 inonamirwa pa700 kusvika 750°C, yokamurwa kuita zvikamu zve25mm, chikamu chimwe nechimwe chonyikwa kwemaawa 1.5. Wobva warega chinhu chacho chichitonhorera. Chenjerera kudzivirira kuomarara panguva yekupisa. Hunhu hwemuchina uye kuramba ngura kwegiredhi iri zvinokanganiswa nekudzimwa kwechinhu.
Nzira dzekubatanidza dzinoshandiswa pasimbi dzisina ngura dzinoshandiswa pakugadzira simbi dzisina ngura dzinogona kushandiswa pasimbi dzisina ngura dzemhando ye3CR12. Funga nezve matekinoroji ekuisa kupisa kushoma akadai seGMAW (MIG) neGTAW (TIG). Mukugadzira simbi, waya yekuzadza yemhando ye309 yakanyoreswa kare kuti ive AS 1554.6 ndiyo inofarirwa. Zvisinei, waya dzemhando ye308L, 316L, 309Mo uye 309L dzinoshandiswawo muzviitiko zvakawanda. Chero kusvibiswa kweruvara rwechinhu chakasungirirwa kunogona kubviswa uchishandisa gasi rekutsigira kana matekiniki akadai sekuchenesa nekusunga.
Kugona kushanda kwesimbi isina tsvina yemhando ye3CR12 kunosvika 60% yesimbi isina kusimba. Kushanda kwayo kwakaderera pane kwesimbi dzinoshandiswa, saka hapana nzira dzakanyanya dzekugadzira dzinodiwa.
Mapepa esimbi isina ngura eGiredhi 3CR12 anowanikwa muchimiro cheHot Rolled Annealed and Pickled (HRAP), uye macoil anowanikwa muchimiro che2B kana 2D. Mapepa matema anogona kugadzirwawo nezvinhu zvinopisa, zvichisiya nzvimbo nhema yakasanganiswa nesimbi. Mapepa matema eGiredhi 3CR12 ane simba rakanaka rekudzivirira ngura uye kukweshana kushoma, saka akakodzera kushandiswa kwakasiyana-siyana.
