Stainless steel haina tsvina zvechokwadi here?
Simbi yeStainless (Stainless Steel) inoshingirira kumhepo, chiutsi, mvura uye zvimwe zvinopisa zvisina kusimba kana simbi isina simbi. Kudzivirirwa kwayo kwekuora kunoenderana nezvinhu zvealloy zviri musimbi. Kazhinji, iyo chromium yemukati yakakura kupfuura 12% uye ine Corrosive simbi inonzi Stainless simbi. Chromium ndicho chinhu chakakosha pakuwana corrosion resistance yesimbi isina tsvina. Kana iyo chromium iri musimbi inosvika 12%, chromium inosangana neokisijeni munzvimbo inoora kuita firimu rakatetepa reoxide (passivation film) pamusoro pesimbi. ) Kudzivirira kuwedzera kuparara kwesimbi substrate. Kana iyo oxide firimu ikaramba ichikuvadzwa, maatomu eokisijeni ari mumhepo kana mvura acharamba achipinda kana kuti maatomu esimbi ari musimbi acharamba achiparadzana, achigadzira yakasununguka iron oxide, uye simbi isina tsvina inoramba iine ngura.
Saizi yeStainless simbi inorwisa-corrosion kugona inoshanduka nekemikari yesimbi pachayo, mamiriro ekudzivirira, mamiriro ekushandiswa, uye mhando yepakati yezvakatipoteredza. Semuyenzaniso, 304 simbi pombi ine zvakanakisa kupikisa ngura mumhepo yakaoma uye yakachena, asi ichaita ngura nekukurumidza kana yaendeswa kumahombekombe egungwa mumhute yegungwa ine munyu wakawanda. kugona. Nokudaro, haisi yemhando ipi neipi yesimbi isina tsvina, iyo inogona kurwisana nekuora uye marara pasi pemamiriro ezvinhu.
