Umbuzo woku-1:
Kutheni intsimbi engenasici nayo inamandla?
I-304 yentsimbi engenasici inesinyithi esingenasici se-austenitic. I-Austenite inxenye okanye isixa esincinci esiguqulwe saba yimartensite ngexesha lokusebenza okubandayo. IMartensite yimagnethi, ke ngoko intsimbi engama-304 engenasici ayiyomagnethi okanye imagnethi kancinane.
Umbuzo 2:
Kutheni irusi yentsimbi engenasici?
a. Umphezulu wensimbi engenasici uqokelele uthuli oluqulathe ezinye izinto zentsimbi okanye iziqhoboshelo zerhasi yentsimbi yangaphandle. Emoyeni ofumileyo, amanzi agudileyo phakathi kweziqhotyoshelweyo kunye nentsimbi engenasici idibanisa zombini ibhetri encinci, eqala ukusabela kwe-electrochemical, Ifilimu ekhuselayo yonakele, ebizwa ngokuba kukubola kwe-electrochemical.
b. Umphezulu wentsimbi engenasici unamathela kwijusi yendalo (njengemelon, imifuno, isuphu yenadusi, isikhohlela, njl.njl.), Eyenza i-asidi ye-organic phambi kwamanzi kunye neoksijini, kwaye i-asidi ye-organic iya konakalisa umphezulu wesinyithi ixesha elide ixesha.
c. Umphezulu wentsimbi engagqwaliyo ubambelela kwiasidi, ialkali, kunye nezinto zetyuwa (ezinje ngamanzi ealkali kunye nekalika yamanzi atshiza eludongeni lokuhombisa), ebangela umhlwa wendawo.
d. Emoyeni ongcolileyo (ofana nomoya ojikeleze isixa esikhulu se-sulfide, i-carbon oxide, kunye ne-nitrogen oxide), uyakwenza isulfuric acid, i-nitric acid, kunye ne-acetic acid yolwelo amabala xa udibana namanzi afinyeziweyo, abangele umhlwa weekhemikhali.
Umbuzo 3:
Ungazichonga njani iimveliso zentsimbi ezingama-304 zokwenene?
A. Inkxaso ye-304 yentsimbi yokuhlola uhlalutyo olukhethekileyo, ukuba ayitshintshi umbala, yintsimbi engama-304.
B. Inkxaso yohlalutyo lobume bemichiza kunye nohlalutyo lwembonakalo.
C. Ukuxhasa umsi wovavanyo lokulinganisa imeko yokusetyenziswa eyiyo.
Umbuzo 4:
Zeziphi iintlobo eziqhelekileyo zensimbi engenasici?
A.201 intsimbi engenasici, efanelekileyo ukusetyenziswa kwiindawo ezomileyo, kulula ukurusa xa udibana namanzi.
B.304 intsimbi engenasici, indawo engaphandle okanye efumileyo, umhlwa oqinileyo kunye nokumelana neasidi.
C.316 insimbi engenasici, eyongeziweyo i-molybdenum, inqabile ngakumbi ukubola, ngakumbi efanelekileyo kulwandle lwamanzi kunye nemithombo yeendaba zamachiza.
