Pakati pemhando dzakasiyana dzesimbi isina tsvina, mamakisi 304, 304L, uye 304H anowanzoshandiswa. Kunyange zvazvo vangaratidzika zvakafanana, giredhi rimwe nerimwe rine zvimiro zvaro zvakasiyana uye mashandisirwo.
Giredhi304 simbi isina tsvinandiyo inonyanya kushandiswa uye inoshandiswa zvakasiyana-siyana ye300 series stainless steels. Iine 18-20% chromium uye 8-10.5% nickel, pamwe chete nekabhoni shoma, manganese, uye silicon. Iri giredhi rine yakanakisa corrosion resistance uye yakanaka formability. Inowanzoshandiswa mumashandisirwo akadai semidziyo yekicheni, kugadzira chikafu, uye kushongedza kwekuvaka.
304L Stainless simbi pombindeye yakaderera kabhoni simbi pombi musiyano wegiredhi 304, ine yakanyanya kabhoni yemukati ye0.03%. Iyi yakaderera kabhoni yemukati inobatsira kudzikisira kunaya kwecarbide panguva yewelding, ichiita kuti ive yakakodzera kune welding application. Iyo yakaderera kabhoni yemukati zvakare inoderedza njodzi yekunzwa, iko kuumbwa kwechromium carbides pamiganhu yezviyo, izvo zvinogona kutungamirira kune intergranular corrosion. 304L inowanzo shandiswa mumashandisirwo emagetsi, pamwe nenzvimbo dzine njodzi yekuora, senge kugadzira makemikari nemidziyo yemishonga.
304H simbi isina tsvinaimhando yepamusoro yekabhoni yegiredhi 304, ine kabhoni inotangira pa0.04-0.10%. Iyo yakakwira kabhoni yemukati inopa zvirinani tembiricha yakasimba uye inokambaira kuramba. Izvi zvinoita kuti 304H ikwane kune yakakwira tembiricha kunyorera, senge midziyo yekumanikidza, inotsinhanisa kupisa, uye mabhailer emaindasitiri. Nekudaro, iyo yakakwira kabhoni yemukati inoitawo kuti 304H ive nyore kunzwisiswa uye intergranular corrosion, kunyanya mumashandisirwo emagetsi.
Muchidimbu, mutsauko mukuru pakati pemagiredhi aya ndeye kabhoni yemukati uye mabatiro pawelding uye yakanyanya tembiricha yekushandisa. Giredhi 304 ndiyo inonyanya kushandiswa uye chinangwa chakajairwa, nepo 304L iriyo sarudzo yakasarudzika yewelding application uye nharaunda umo ngura iri kunetseka. 304H ine yakakwira kabhoni yemukati uye inokodzera kukwirisa tembiricha kunyorera, asi kukonzeresa kwayo kwekunzwa uye intergranular corrosion inoda kunyatsotariswa. Pakusarudza pakati pemagiredhi aya, zvakakosha kuti utarise izvo chaizvo zvinodikanwa zvekushandisa, kusanganisira nharaunda yekushanda, tembiricha, uye welding zvinodiwa.
