304 vs 316 Stainless Simbi: Heat Resistance
Kupisa kupisa chinhu chakakosha chekufunga kana uchienzanisa mamakisi akasiyana esimbi isina tsvina. Kunyunguduka kwe304 kwakapoteredza 50 kusvika ku100 degrees Fahrenheit yakakwirira kudarika 316. Kunyange zvazvo kunyunguduka kwe304 kwakakwirira kudarika 316, ivo vose vane kurwisana kwakanaka kune oxidization mubasa repakati kusvika ku870 ° C (1500 ℉) uye mubasa rinoramba riripo. pa925°C (1697℉).
304 SS: Inobata kupisa kwakanyanya zvakanaka, asi kushandiswa kunoramba kuripo pa425-860 °C (797-1580 °F) kunogona kukonzera ngura.
316 SS: Inoita zvakanyanya mukupisa kuri pamusoro pe843 ℃ (1550 ℉) uye pasi pe454 ℃ (850°F)
Mutengo Musiyano we304 Stainless Steel vs 316
Chii chinoita kuti 316 iwedzere kudhura kupfuura 304 simbi isina tsvina?
Kuwedzera kwehuwandu hwe nickel uye kuwedzera kwe molybdenum mu 316 kunoita kuti iwedzere kudhura kupfuura 304. Paavhareji, mutengo we 316 simbi isina tsvina 40% yakakwirira kudarika mutengo we304 SS.
316 vs 304 Stainless Simbi: Ndeipi iri Nani?
Kana tichienzanisa 304 Stainless steel vs 316, vese vane zvazvakanakira nezvazvakaipira zvekufunga nezvazvo pakusarudza kuti ndeipi yekushandisa pamaapplication akasiyana. Semuyenzaniso, 316 simbi isina tsvina inoshingirira kupfuura 304 kumunyu nezvimwe zvinopisa. Saka, kana uri kugadzira chigadzirwa chinowanzotarisana nemakemikari kana nharaunda yegungwa, 316 ndiyo sarudzo iri nani.
Kune rimwe divi, kana iwe uri kugadzira chigadzirwa chisingadi yakasimba corrosion resistance, 304 isarudzo inoshanda uye ine hupfumi. Kune akawanda maapplication, 304 uye 316 ari kunyatso chinjana.
Jindalai Steel Group inyanzvi uye inotungamira mutengesi musimbi uye simbi isina tsvina. Tumira kubvunza kwako uye isu tichafara kukubvunza iwe nehunyanzvi.
