Pakati pemhando dzakasiyana dzesimbi dzesimbi, mamakisi 304, 304l, uye 304h zvinowanzo shandiswa. Nepo vangataridzika zvakafanana, giredhi rega rega rine zvaro zvakasarudzika zvivakwa uye zvinoshandiswa.
Giredhi304 simbi isina tsvinandiyo inonyanya kushandiswa uye yakawandisa yeiyo mazana matatu akatevedzana stainless simbi. Iyo ine 18-20% chromium uye 8-10,5% nickel, pamwe nezvidiki zvidiki zve kabhoni, mangaanese, uye silicon. Iyi giredhi ine yakanakisa kurwisa kurwisa uye kurongeka kwakanaka. Zvinowanzoshandiswa mukushandisa senge kicheni michina, chikafu chekugadzirisa, uye kuvaka kuvaka.
304l stainless simbi pombiis a low carbon simbi pombi kusiyana kwegiredhi 304, ine yakakwira kabhoni yezvinyorwa zve003%. Iyi yakaderera carbon zvemukati inobatsira kudzikisira carbide precipitation panguva yekuisa, ichiita kuti iite kuti iite kuti iite kuti iite kuti utarise. Iyo yepazasi kabhoni yezvinyorwa inoderedzawo njodzi yekunzwa, iyo ndiyo yekuumbwa kweChromium carbides pamiganhu yezviyo, iyo inogona kutungamira mukuwirirana kweCorrostion. 304L inowanzoshandiswa muWelding Zvikumbiro, pamwe nenzvimbo dzine njodzi yekukanganisa kunetseka, senge makemikari ekugadzirisa uye mishonga yemishonga.
304h simbi isina tsvinaIcho chakakwira kabhoni vhezheni yegiredhi 304, ine kabhoni yezvinyorwa kubva pa0,04-0.1%. Iyo yakakwira kabhoni yezvinyorwa inopa iri nani kupisa simba resimba uye kupokana kwekukanda. Izvi zvinoita 304h zvakakodzera kuti zvinyoronyoro zvekupisa, sekumanikidza midziyo, kupisa kutsinhana, uye mabhodhi maindasitiri. Nekudaro, iyo yepamusoro carbon yezvinyorwa inoita kuti 304H iwedzere kutarisana nekunyepedzera uye kuyamwisa corrosion, kunyanya mukushandisa mashandisiro ekushandisa.
Mukupfupikisa, musiyano mukuru pakati pemamiridhi aya ndeye kabhoni yavo uye mhedzisiro yekufambisa uye yakanyanya tembiricha yekukurudzira. Giredhi 304 ndiyo inonyanya kushandiswa uye yakajairika chinangwa, nepo 304l isarudzo yakasarudzika yekushandisa maficha uye nharaunda iyo kuronga kunetseka. 304h ine yakakwira kabhoni zvemukati uye yakakodzera kune yakanyanya tembiricha yekudziya, asi yayo yekunyepedzera kuti isimbise uye yekudyara corrostion inoda kunyatsofungisisa. Kana uchisarudza pakati pemakiredhi aya, zvakakosha kufunga nezve izvo zvinodiwa zvekushandisa, kusanganisira nharaunda yekushandisa, tembiricha, uye tuling zvinodiwa.
