Simbi isina simbi inotora zita rayo kubva mukugona kwayo kuramba ngura nekuda kwekudyidzana pakati pezvikamu zvayo zvealloying uye nharaunda yavanovhenekwa. Mhando dzakawanda dzesimbi isina tsvina dzinoshanda zvakasiyana-siyana uye dzakawanda dzinopindirana. Masimbi ese asina tsvina anoumbwa ne10% chromium. Asi haasi ese masimbi asina tsvina akafanana.
Stainless Simbi Grading
Rudzi rumwe norumwe rwesimbi isina tsvina inoiswa graded, kazhinji munhevedzano. Aya akatevedzana anoisa mhando dzakasiyana dzestainless kubva pa200 kusvika 600, aine akawanda mapoka pakati. Imwe neimwe inouya neyakasiyana zvivakwa uye inowira mumhuri dzinosanganisira:
- austenitic:isiri-magnetic
- ferritic: magnetic
- duplex
- martensitic uye kunaya kwemvura kuoma:simba rakakwirira uye kupikisa kwakanaka kune ngura
Pano, tinotsanangura mutsauko pakati pemhando mbiri dzinowanikwa pamusika - 304 uye 304L.
Nyora 304 Stainless Simbi
Type 304 ndiyo inonyanya kushandiswa austeniticstainlesssimbi. Iyo inozivikanwa zvakare se "18/8" simbi isina simbi nekuda kwekuumbwa kwayo, iyo inosanganisira 18%chromiumuye 8%nickel. Type 304 Stainless simbi ine yakanaka kuumba uye welding zvivakwa pamwe nekusimbangurakuramba uye simba.
Iri rudzi rwesimbi isina tsvina zvakare ine yakanaka yekudhirowa. Inogona kuumbwa kuita akasiyana maumbirwo uye, mukupesana nemhando 302 isina tsvina, inogona kushandiswa isina annealing, kupisa kupisa kunopfavisa simbi. Kushandiswa kwakajairika kwemhando 304 simbi isina tsvina inowanikwa muindasitiri yechikafu. Yakanakira kubika, kugadzira mukaka, nekugadzira waini. Inokodzerawo mapaipi, pani mbiriso, vheti dzekuvirisa, uye matangi ekuchengetera
Type 304 giredhi Stainless simbi inowanikwawo mumasingi, matabletop, mapoto ekofi, mafiriji, zvitofu, midziyo, nemimwe midziyo yekubikira. Inogona kumira nekuora kunogona kukonzerwa nemakemikari akasiyana-siyana anowanikwa mumichero, nyama, nemukaka. Dzimwe nzvimbo dzekushandisa dzinosanganisira zvivakwa, midziyo yemakemikari, zvinopisa kupisa, midziyo yemugodhi, pamwe nenzungu dzemugungwa, mabhaudhi, uye screws. Type 304 inoshandiswawo mumigodhi nemvura yekusefa masisitimu uye muindasitiri yekudhaya.
Nyora 304L Stainless Simbi
Type 304L Stainless simbi ndeye yakawedzera-yakaderera kabhoni shanduro ye304 simbialloy. Iyo yakaderera kabhoni yemukati mu304L inoderedza inodzima kana inokuvadza carbide kunaya semhedzisiro yewelding. 304L inogona, saka, kushandiswa “seyakaiswa simbi” munzvimbo dzine ngura dzakakomba, uye inobvisa kudiwa kweannealing.
Iri giredhi rine zvishoma rakadzikira michina zvivakwa pane yakajairwa 304 giredhi, asi richiri kushandiswa zvakanyanya nekuda kwekuita kwayo kwakasiyana-siyana. Kufanana neType 304 simbi isina tsvina, inowanzoshandiswa mukubika doro nekugadzira waini, asiwo kune zvinangwa zvinopfuura indasitiri yechikafu senge mumidziyo yemakemikari, migodhi, uye kuvaka. Yakanakira kushandiswa muzvikamu zvesimbi senge nzungu uye mabhaudhi anowanikwa mumvura yemunyu.
