Farsamada:
- sawirid: Ku sawirida bannaan duuban ee godka dhinta ee qayb ka mid ah si loo yareeyo kororka dhererka
- Duubista: maran waxa la dhex maraa farqiga u dhexeeya laba roller oo wareeg ah.Sababtoo ah isku-dhafka rookaha, qaybta walxaha waa la dhimay dhererkuna waa la kordhiyaa.Tani waa hab caadi ah oo lagu soo saaro tuubooyinka birta
- Been abuurasho: Si aad u beddesho meesha bannaan una beddelo qaabka iyo cabbirka la doonayo adiga oo isticmaalaya xoogga saamaynta soo noqnoqda ee dubbaha ama cadaadiska saxaafadda
- Soo saarid: Madhan waxa lagu ridayaa weel xidhan oo cadaadis lagu saarayo gees ka mid ah si looga saaro meesha banaan ee godka dhiman ee la cayimay si loo helo qaabab iyo cabbiro kala duwan
Astaamaha:904Lwaa kaarboon hoose, bir daxalka austenitic ah oo sarreeya oo loogu talagalay xaaladaha daxalka adag.Waxay leedahay iska caabbinta daxalka ka fiican 316L iyo 317L, waxayna isku daraa qiimaha iyo waxqabadka, oo leh waxqabad qiimo sare leh. Sababtoo ah ku darista 1.5% copper, waxay leedahay iska caabin aad u fiican si loo yareeyo acids sida sulfuric acid iyo phosphoric acid.
