Kule mihla, intsimbi engenastainless isetyenziswa kakhulu kubomi bethu, ukusuka kwizixhobo ze-aerospace ukuya kwiimbiza kunye neepani. Namhlanje, siya kwabelana ngezinto eziqhelekileyo zensimbi engenasici 304 kunye ne-316.
Umahluko phakathi kwe-304 kunye ne-316
I-304 kunye ne-316 yimigangatho yaseMelika. I-3 imele i-300 series steel. Amanani amabini okugqibela ngamanani alandelelanayo. I-304 I-brand yaseTshayina yi-06Cr19Ni9 (equkethe ngaphantsi kwe-0.06% C, ngaphezu kwe-19% ye-chromium kunye ne-nickel engaphezu kwe-9%); I-316 I-brand yaseTshayina yi-06Cr17Ni12Mo2 (equkethe ngaphantsi kwe-0.06% C, ngaphezu kwe-17% ye-chromium, ngaphezu kwe-12% ye-nickel kunye ne-2% ye-molybdenum).
Kukholelwa ukuba sinokubona kwakhona kwi-brand ukuba ukubunjwa kweekhemikhali ze-304 kunye ne-316 kuyahluka, kwaye umahluko omkhulu obangelwa ukubunjwa okuhlukeneyo kukuba ukuxhathisa kwe-asidi kunye nokuxhatshazwa kwe-corrosion kuyahluka. Xa kuthelekiswa nesigaba se-304, isigaba se-316 sinokunyuka kwe-nickel kunye ne-nickel, ngaphezu koko, i-molybdenum kunye ne-molybdenum yongezwa. Ukongeza i-nickel kunokuphucula ngakumbi ukuqina, iipropathi zoomatshini kunye nokumelana ne-oxidation yensimbi engenasici. I-Molybdenum inokuphucula i-corrosion ye-atmospheric, ngakumbi i-corrosion ye-atmospheric ene-chloride. Ngoko ke, ukongeza kwiimpawu zokusebenza ze-304 yensimbi engenasici, i-316 insimbi engenasici iphinda ixhathise ukubola kweendaba ezikhethekileyo, ezinokuthi ziphucule ukunyanzeliswa kwe-corrosion ye-chemical hydrochloric acid kunye nolwandle, kunye nokuphucula ukuxhathisa kwe-corrosion ye-brine halogen solution.
Uluhlu lwezicelo lwe-304 kunye ne-316
I-304 insimbi engenasici isetyenziswa ngokubanzi, njengempahla yasekhitshini kunye netafile, umhlobiso wokwakha, ishishini lokutya, ezolimo, iinxalenye zeenqanawa, igumbi lokuhlambela, iindawo zemoto, njl.
Ixabiso le-316 yensimbi engenasici iphezulu kune-304. Xa kuthelekiswa ne-304, i-316 insimbi engenasici inokumelana ne-asidi enamandla kunye nokuzinza okungcono. I-316 insimbi engenasici isetyenziswa kakhulu kwishishini lemichiza, idayi, ukwenza iphepha, i-acetic acid, isichumisi kunye nezinye izixhobo zokuvelisa, ishishini lokutya kunye nezibonelelo zonxweme, kunye neemveliso ezineemfuno ezikhethekileyo zokumelana ne-intergranular corrosion.
Ubomi bemihla ngemihla, i-304 insimbi engenasici inokuhlangabezana neemfuno zethu, kwaye i-304 nayo iyinto yensimbi engenasici ehlangabezana ngokupheleleyo nomgangatho wokutya.
