Maxaa ka dhigaya 304 vs 316 oo caan ah?
Heerarka sare ee koromium iyo nikkel laga helay 304 iyo 316 bir bir ah ayaa iyaga siiya iska caabbinta adag ee kuleylka, diidanka, iyo hubedda. Kaliya maahan inay u ogaadaan iska caabintooda hudheelka, sidoo kale waxaa lagu yaqaanaa muuqaalkooda nadiifka ah iyo isbarbardhiga guud.
Labada nooc ee bir bir aan jaranjaradu u muuqdaan warshadaha-uqalma. 304 Birta aan sal lahayn ayaa si ballaaran loo istcimaalaa maxaa yeelay waa mid waara oo ay fududahay in loo sameeyo qaabab kala duwan oo bir ah oo bir bir ah, saxan bir bir ah, bir bir aan lahayn, iyo tuubbada birta. 316 Iidanka ugu caabbinta ee kiimikada ee kiimikada iyo jawiga badda ayaa ka dhigaya xulasho caan ah oo ka mid ah soosaarayaasha.
Sidee loo kala saaraa?
Shanta fasal ee birta balaaran ayaa loo habeeyey iyadoo lagu saleynayo qaab dhismeedkooda (sida atomas loogu diyaariyo). Shanta fasal, 304 iyo 316 bir aan birn lahayn ayaa ku jira fasalka austenitic fasalka. Qaab-dhismeedka shaashadda ee aan caadiga ahayn ee aan la dhisaneyn waxay ka dhigeysaa wax aan la jirin oo aan ka horjoogsanin inay ku adkaato kuleylka.

Codsiyada 316 bir aan argagax lahayn
Ku darista molybdenum 316 waxay ka dhigeysaa mid aad u adag oo ka sii adkaysata ka badan akoorrada la midka ah. Sababta oo ah iska caabbinta sareeya ee laxiriira, 316 waa mid ka mid ah biraha xarkaha ee jawiga badda. 316 Steel aan bir lahayn ayaa sidoo kale loo adeegsadaa isbitaalada sababtoo ah cimrigeeda iyo nabarradeeda.

304 vs 316 birta aan dhagaxa lahayn: iska caabin kuleylka
Iska caabbinta kuleylka ayaa ah cunsur muhiim ah oo laga qaddariyo marka la barbar dhigo heerarka kala duwan ee birta wasakhda leh. Isugeynta dhalaalaya 304 illaa 100 darajo Fahrenheit ka sareysa 316. In kasta oo ay ka sarreeyaan 316 labaduba, labaduba waxay ka sarreeyaan adeegsiga si joogto ah ilaa 870 ° C (1600 ° C (1697 ℉).
304 SS: Si fiican u qabtaa kuleyl aad u sareeya, laakiin isticmaal joogto ah 425-860 ° C (797-1580 ° F) ayaa sababi kara dax-gaar.
316 SS: Wuxuu ku sameeyaa ugu wanaagsan heerkulka ka sarreeya 843 ℃ (1550 ℉) iyo ka hooseeya 454 ℃ (850 ° F)
Farqiga qiimaha ee 304 steel aan lahayn vs 316
Maxaa ka dhigaya 316 ka qaalisan 304 bir aan argagax lahayn?
Kordhinta nuckeelka Nickel iyo ku darista molybdenum 316 waxay ka dhigeysaa ka qaalisan 304. Celcelis ahaan, qiimaha 316 bir-bir ah oo ka sarreeya qiimaha 304 ss.
316 vs 304 bir bir ah: yaa ka fiican?
Markii la barbar dhigo 304 steel aan sal lahayn. Tusaale ahaan, 316 bir aan biqil lahayn ayaa aad uga adkaysata in ka badan 304 cusbo iyo waxyaabaha kale ee loo yaqaan '. Marka, haddii aad soosaareyso wax soo saar inta badan la kulmaya soo-gaadhista kiimikada ama jawi badda, 316 waa doorashada ugu fiican.
Dhanka kale, haddii aad soosaarayso wax soo saar aan u baahnayn iska caabin da 'ah oo xoog leh, 304 waa xulasho wax ku ool ah oo dhaqaale. Codsiyo badan, 304 iyo 316 dhab ahaantii waa isweydaarsiga.
