Tiwb Coil Dur Di-staen SS 310 Cyflenwr Tiwbiau Coiled

Tiwb Coil Dur Di-staen SS 310 Cyflenwr Tiwbio Coiled Delwedd dan Sylw

Disgrifiad Byr:

Mae Tiwbiau Coil Dur Di-staen 304 yn gallu gwrthsefyll cracio cyrydiad straen ïon clorid, cracio cyrydiad purdeb uchel, cyrydiad dŵr a chastig.Felly, mae'r math hwn o aloi yn ddelfrydol ar gyfer cydrannau ffwrnais, prosesu cemegol a bwyd, technoleg niwclear ac electrodau gwreichionen.Fodd bynnag, mae ganddo gryfder uwch nag aloion eraill ar dymheredd is.Wrth benderfynu rhwng y ddau aloi gwahanol, cost, tymheredd a chryfder yw'r ffactorau pwysicaf yma mewn Tiwbiau Coil Dur Di-staen 304L.Os oes angen rhan lai costus ond cymharol gryf, mae'n debyg mai dyma'r ffordd i fynd.Os oes angen cydran aer hanfodol gyda gofynion tymheredd uchel, yna mae'n aloi llawer gwell ar gyfer y cais.Mae ganddo sylfaen cromiwm-nicel ac mae'n gallu gwrthsefyll cyrydiad.Mae hyn yn ei gwneud yn ddelfrydol mewn amgylcheddau eithafol gyda phwysau a gwres.

Tagiau Cynnyrch

Er enghraifft, nhw fydd y radd fwyaf hydwyth o ddur, ond hefyd y mwyaf gwrthsefyll cyrydiad.Ar y llaw arall, mae gan y dosbarth martensitig hwn gryfder llawer uwch ond ymwrthedd cyrydiad is.Mae gan Diwbiau Coil Dur Di-staen 316 strwythur grawn mwy, mwy unffurf sy'n rhoi'r priodweddau hyn iddynt o'i gymharu â'r strwythur dirdro llai a geir mewn dur martensitig.Mae'n grŵp amrywiol o aloion a geir drwyddi draw o gyllyll a ffyrc cegin i gymwysiadau peirianneg, cymwysiadau biofeddygol a pharatoi bwyd.Mae ganddo hefyd ymwrthedd cyrydiad llawer gwell a gwrthiant tymheredd uchel.
