Kusiyana kwa Mtengo wa 304 Stainless Steel vs 316
Nchiyani chimapangitsa 316 kukhala okwera mtengo kuposa 304 chitsulo chosapanga dzimbiri?
Kuwonjezeka kwa nickel content ndi kuwonjezera kwa molybdenum mu 316 kumapangitsa kukhala okwera mtengo kuposa 304. Pafupifupi, mtengo wa 316 zitsulo zosapanga dzimbiri 40% kuposa mtengo wa 304 SS.
316 vs 304 Chitsulo chosapanga dzimbiri: Chabwino n'chiti?
Poyerekeza 304 zitsulo zosapanga dzimbiri vs 316, onse ali ndi zabwino ndi zoyipa zomwe ayenera kuziganizira posankha kuti ndi iti yomwe angagwiritse ntchito pazinthu zosiyanasiyana. Mwachitsanzo, chitsulo chosapanga dzimbiri cha 316 sichimva bwino kuposa 304 ku mchere ndi zina zowononga. Chifukwa chake, ngati mukupanga chinthu chomwe nthawi zambiri chimakumana ndi mankhwala kapena malo am'madzi, 316 ndiye chisankho chabwinoko.
Kumbali ina, ngati mukupanga chinthu chomwe sichifunikira kukana kwa dzimbiri, 304 ndi chisankho chothandiza komanso chachuma. Pazinthu zambiri, 304 ndi 316 ndizosinthana.
Jindalai Steel Group ndi katswiri komanso wogulitsa zitsulo ndi zitsulo zosapanga dzimbiri. Tumizani kufunsa kwanu ndipo tidzakhala okondwa kukufunsani mwaukadaulo.
