304 Stainless simbi precision simbi chubhu inobatsira zvikuru, kunyanya muindasitiri yemagetsi, uko inogona kuwanikwa kwese kwese. Simbi isina simbi inogona kuwana nhanho muindasitiri yemagetsi ine mabhenefiti ayo maviri ekuchengetedza, hutsanana, uye kusakara. Heano mamwe anomiririra zvikumbiro.

Chokutanga pane zvose, zvikamu zvinosangana zvakananga nechikafu. 304 simbi isina tsvina yakanyatsojeka simbi chubhu yakaenzana ne "pombi" sepombi yemvura. Kusangana kwakananga nemvura yekunwa kunonyanya kunyanya nezvekuchengetedza uye hutsanana hwezvinhu. 304 simbi isina tsvina inozivikanwa nenyika sechikafu-giredhi simbi isina tsvina. Kunaya kwemvura inorema se arsenic, cadmium, lead, chromium, uye nickel inosangana nemiyero yakaoma. Kuti uwane ruzivo, ndapota tarisa ku "GB 4806.9-2016 National Food Safety Standard".

Iyo pombi fittings inoshandisa nzira yekupukuta kubvisa yakawedzera kureba kwemukati pombi wall weld. Rusvingo rwepombi runogona kukwenenzverwa kuita girazi mhedzisiro, iyo inovandudza kushorwa kwengura uye kuyera kupikisa kwepombi yesimbi isina tsvina uye inobvisa girisi kuti iwane utsanana hunodiwa negiredhi rekudya, saka inogona kushandiswa nekuvimba. Iyo ductility ye304 simbi isina tsvina precision simbi chubhu ndeye δ5 (%) ≥ 40, kuoma ≤ 201HBW, ≤ 92HRB, ≤ 210HV; hazvisi nyore kutyora kana uchikotama, uye inogona kukotama mune chero kona, iine yakanakisa kugadzirisa mashandiro, ichidzikisa zvakanyanya mwero wezvikara, uye nekuchengetedza zvakanyanya mari.

Pamusoro pezvo, inoshandiswa sechubhu yekutsinhanisa kupisa mumagasi emvura inopisa, iyo yave iri munzvimbo yakakwirira yekupisa uye yakanyorova kwenguva yakareba, uye ine zvinodiwa zvakasimba pakudzivirira kusimba uye kupisa kwakanyanya. 304 simbi isina tsvina inokwanisa kumira tembiricha yakakwira ye800 madhigirii celsius, uye yayo thermal conductivity (W·m-1·K-1): (100 ℃) 16.3, (500 ℃) 21.5, ndiyo yakanakisa sarudzo yegasi mvura hita yekutsinhanisa kupisa. machubhu. 304 simbi isina tsvina yakanyatsogadziriswa machubhu anobatwa neyakajeka mhinduro annealing, iyo inopisa chubhu yesimbi pakupisa kwakanyanya uye nekukasira kuitonhodza pasi, inonyungudutsa carbides musangano, inonatsiridza kushora kwechubhu, uye inowedzera hupenyu hwesevhisi yekupisa. exchange chubhu. Kunyatsokwenenzverwa kunoshandiswa kuvandudza kutsetseka kwemukati chubhu madziro, kuita kuti chubhu madziro irambe iine corrosion uye kuyera, uye kunatsiridza kupisa kwekufambisa kuita; simbi isina tsvina iri nyore kucheka uye inogona kugadzirwa kuita machubhu akatetepa. Pamusoro pekuvandudza mashandiro ekutamisa kupisa, inogona zvakare kuchengetedza mutengo, uye kuita uye hupfumi zvinogara.

Izvo zviri pamusoro ndiko kushandiswa kwemachubhu 304 esimbi isina tsvina muindasitiri yemagetsi sekusangana kwakananga nechikafu uye semachubhu ekutsinhana kupisa. Mushure mekuongorora kwakadzama kwezvivakwa zvezvinhu uye mashandiro ekugadzirisa, zvinodzidzwa kuti 304 Stainless simbi precision simbi machubhu anogona zvakare kushandiswa nenzira iyi.
