◉Kuluntu lwanamhlanje, insimbi engenasici iye yaba yinto eqhelekileyo kunye nebalulekileyo esetyenziswa ngokubanzi kulwakhiwo, ukuvelisa kunye nobomi bemihla ngemihla. Kukho iintlobo ezininzi ezahlukeneyo zensimbi engenasici, kuquka iimodeli eziqhelekileyo ezifana ne-201, 304 kunye316.
Nangona kunjalo, kulabo abangaziqondi iimpawu zezinto eziphathekayo, kulula ukudideka ngokuhlukana phakathi kwale mizekelo. Eli nqaku liza kuchaza iiyantlukwano phakathi kwensimbi engenasici 201, 304 kunye ne-316 ukunceda abafundi baqonde ngcono iimodeli ezahlukeneyo zemathiriyeli yensimbi engenasici kunye nokubonelela ngeengcebiso zokuthenga insimbi engenasici.
◉Okokuqala, umahluko ekubunjweni kweekhemikhali
Ukubunjwa kweekhemikhali zensimbi engenasici yinto ebalulekileyo ekunqumeni ukusebenza kwayo kunye neempawu.Intsimbi engatyiwa 201, 304 kunye ne-316 kukho ukungafani okucacileyo ekubunjweni kweekhemikhali. steel stainless 201 iqulathe 17.5% -19.5% chromium, 3.5% -5.5% nickel, lo kunye 0.1% -0.5% nitrogen, kodwa akukho molybdenum.
I-stainless steel 304, ngakolunye uhlangothi, iqulethe i-18% -20% ye-chromium, i-8% -10.5% ye-nickel, kwaye akukho nitrogen okanye i-molybdenum. Ngokwahlukileyo, i-stainless steel 316 iqulethe i-16% -18% ye-chromium, i-10% -14% ye-nickel, kunye ne-2% -3% ye-molybdenum. Ukusuka kukwakheka kweekhemikhali, i-stainless steel 316 inokumelana ne-corrosion ephezulu kunye nokumelana ne-asidi, ifaneleke ngakumbi ukusetyenziswa kwezinye iindawo ezikhethekileyo kunentsimbi ye-201 kunye ne-304.
◉Okwesibini, umahluko kwi-corrosion resistance
Ukumelana ne-Corrosion yisalathisi esibalulekileyo sokusebenza kwensimbi engenasici. Insimbi engagqwali i-201 inokumelana nokugqwala okulungileyo kwi-acids ezininzi ze-organic, i-acids ye-inorganic kunye nezisombululo zetyuwa kwindawo yokushisa, kodwa iya kugqwala kwindawo eqinile ye-alkaline. Insimbi engagqwali engama-304 inokumelana ne-corrosion elungileyo kwaye ifanelekile kwiindawo ezininzi ezinobungozi.
I-Stainless steel 316, ngakolunye uhlangothi, igqwesa kwi-corrosion resistance, ngokukodwa kwiindawo ezine-acidic kunye neemeko eziphezulu zokushisa ezinokumelana nokugqwesa okugqwesileyo, okuhlala kusetyenziswa kwiikhemikhali, elwandle kunye nezinye izicelo. Ngoko ke, xa uthengela izinto zensimbi ezingenasici, kubalulekile ukukhetha imodeli efanelekileyo ngokubhekiselele kusetyenziso oluthile lweendawo ezahlukeneyo.
◉Okwesithathu, umahluko kwiipropati zoomatshini
Iimpawu zemishini yensimbi engenasici ziquka izikhombisi ezifana namandla, i-ductility kunye nobunzima. Ngokuqhelekileyo, amandla ensimbi engenasici ye-201 iphezulu kancinci kuneyentsimbi ye-304, kodwa iphantsi kakhulu kuneyentsimbi ye-316. I-Stainless steel 201 kunye ne-304 ine-ductility enhle, kulula ukuyiqhuba kunye nokubumba, ifanelekile kwezinye izinto. ukusetyenzwa kweemfuno zokusebenza zezihlandlo eziphezulu.
Amandla aphezulu ensimbi engenasici engama-316, kodwa ikwanazo ukumelana nokunxiba kakuhle kunye nokumelana nokuqina, ilungele ukumelana namandla aphezulu kunye nobushushu obuphezulu bendawo yokusebenza. Ngoko ke, xa ukhetha izinto zensimbi ezingenasici, kufuneka wenze ukhetho olufanelekileyo ngokweemfuno ezithile zoomatshini kunye nokusetyenziswa kwendawo.
◉Okwesine, umahluko wexabiso
Kukho neeyantlukwano kwixabiso le-stainless steel 201, 304 kunye ne-316. Ngokuqhelekileyo, ixabiso le-stainless steel 201 lincinci, lifikeleleke ngakumbi. Ixabiso le-stainless steel 304 liphezulu kakhulu, kodwa ngenxa yoluhlu olubanzi lwezicelo kunye nokusebenza kakuhle ngokubanzi, kuseyenye yeemodeli zensimbi ezingenasici kwimarike.
◉ Intsimbi ye-Stainless 316 iyabiza kakhulu ngenxa yokumelana nokugqwesa okuhle kunye neempawu zoomatshini, kwaye ifanelekile kwezinye iindawo ezikhethekileyo ezifuna iipropati eziphezulu zezinto eziphathekayo. Ngoko ke, xa kuthengwa izinto zensimbi ezingenasici, kufuneka uqwalasele izinto ezifana nokusebenza kwezinto kunye nohlahlo lwabiwo-mali.
