Mazuvano, simbi isina tsvina inoshandiswa zvakanyanya muhupenyu hwedu, kubva pamidziyo yemuchadenga kusvika kumapoto nemapani. Nhasi, tichagovana zvakajairika Stainless simbi 304 uye 316 zvinhu.
Kusiyana pakati pe304 ne316
304 uye 316 zviyero zveAmerica. 3 inomiririra mazana matatu akatevedzana simbi. Madijiti maviri ekupedzisira ndidzo nhamba dzinoverengeka. 304 Chiratidzo cheChinese chinonzi 06Cr19Ni9 (ine isingasviki 0.06% C, inopfuura 19% chromium uye inopfuura 9% nickel); 316 Chiratidzo cheChinese chinonzi 06Cr17Ni12Mo2 (ine isingasviki 0.06% C, inopfuura 17% chromium, inopfuura 12% nickel uye inodarika 2% molybdenum).
Zvinotendwa kuti isu tinogonawo kuona kubva muchiratidzo kuti kemikari ye304 uye 316 yakasiyana, uye mutsauko mukuru unokonzerwa nemhando dzakasiyana-siyana ndeyokuti kupikisa kweasidhi uye kusagadzikana kwemarara kwakasiyana. Kuenzaniswa ne304 chikamu, 316 chikamu chine kuwedzera nickel uye nickel, kuwedzera, molybdenum uye molybdenum inowedzerwa. Kuwedzera nickel kunogona kuwedzera kuvandudza kusimba, michina zvivakwa uye oxidation kuramba kwesimbi isina tsvina. Molybdenum inogona kuvandudza ngura yemuchadenga, kunyanya ngura yemuchadenga ine chloride. Naizvozvo, pamusoro pemaitiro ekuita kwe304 simbi isina tsvina, 316 simbi isina tsvina zvakare inoshingirira mukuora kweakakosha midhiya, iyo inogona kuvandudza kushorwa kwemakemikari hydrochloric acid uye nyanza, uye kunatsiridza kusaonda kwebrine halogen mhinduro.
Maitiro ekushandisa e304 uye 316
304 simbi isina tsvina inoshandiswa zvakanyanya, semidziyo yekicheni uye tafura, kushongedza kwekuvaka, indasitiri yechikafu, kurima, zvikamu zvengarava, imba yekugezera, zvikamu zvemotokari, nezvimwe.
Mutengo we316 simbi isina tsvina wakakwirira kudarika 304. Kuenzaniswa ne304, 316 simbi isina tsvina ine yakasimba acid resistance uye zviri nani kugadzikana. 316 simbi isina tsvina inonyanya kushandiswa muindasitiri yemakemikari, dhayi, kugadzira mapepa, acetic asidhi, fetiraiza uye zvimwe zvigadzirwa zvekugadzira, indasitiri yezvekudya uye zvivakwa zvemahombekombe, uye zvigadzirwa zvine zvakakosha zve intergranular corrosion resistance.
Kwehupenyu hwezuva nezuva, 304 simbi isina tsvina inogona kuzadzisa zvatinoda, uye 304 zvakare isimbi isina tsvina inosangana zvizere nechiyero chekudya.
