Yenziwe ngentsimbi eshayinayo
Ngokutsho kwenkcazo ye-GB / T20878-2007, iimpawu eziphambili zensimbi engenasici, ukuxhatshazwa kwe-corrosion, kunye nomxholo we-chromium ubuncinane ubuncinane be-10.5%, umxholo wekhabhoni ophezulu awukho ngaphezu kwe-1.2%.
Intsimbi engatyiwa (Stainless Steel) imfutshane kwintsimbi enganyangekiyo enganyangekiyo kwiasidi, umoya, umphunga, amanzi kunye nokunye okubuthathaka okuphakathi okanye intsimbi engatyiwa;Kwaye i-chemical corrosion resistant medium (i-asidi, i-alkali, ityuwa kunye nezinye iikhemikhali zokutshiza) ukubola kwentsimbi ebizwa ngokuba yintsimbi enganyangekiyo kwi-asidi.
Ngenxa yomahluko ekubunjweni kweekhemikhali zezi zibini kunye nokuxhathisa ukubola kwazo kwahlukile, isinyithi esiqhelekileyo esingenasici ngokuqhelekileyo asikwazi ukumelana nokubola kwemithombo yeendaba zemichiza, kwaye intsimbi ekwazi ukumelana ne-asidi ayinayo umhlwa.Igama elithi "insimbi engenasici" ayibhekiseli nje kuhlobo lwentsimbi engenanto, kodwa ithetha ngaphezu kwekhulu leentlobo zensimbi engenasici, uphuhliso lwensimbi engenasici nganye lusebenza kakuhle kwintsimi yesicelo sayo.Isitshixo sokuphumelela kukuqala ukufumanisa injongo, kwaye emva koko ukugqiba uhlobo olufanelekileyo lwentsimbi.Ngokuqhelekileyo kukho iintlobo ezintandathu kuphela zetsimbi ezinxulumene nentsimi yesicelo sokwakhiwa kwesakhiwo.Zonke ziqulethe i-17 ukuya kwi-22 yepesenti ye-chromium, kwaye iintsimbi ezingcono ziqulethe i-nickel.Ukongezwa kwe-molybdenum kunokuphucula ngakumbi ukubola kwe-atmospheric, ngakumbi ukuxhathisa kwe-corrosion ye-atmosphere equkethe i-chloride.
Ngokuqhelekileyo, ubunzima bensimbi engenasici buphezulu kune-aluminium alloy, ixabiso lensimbi engenasici liphezulu kunelo aluminium alloy.
