I-316L insimbi engenasici yinto eguquguqukayo kwaye ehlala ixesha elide esetyenziswa ngokubanzi kumashishini ahlukeneyo ngenxa yeempawu zayo ezikhethekileyo. Olu hlobo lwensimbi engenasici luyaziwa ngokusebenza okuphezulu kwiindawo eziphakamileyo zokushisa, kunye nokuchasana nokuxhatshazwa kunye nokuqina. Makhe sijonge nzulu kwinto eyenza i316L yentsimbi engatyiwayo ibe yimathiriyeli emangalisayo.
Okokuqala kunye nokuphambili, i-316L insimbi engenasici i-low-carbon variation ye-316 yensimbi engenasici, eyenza ibe yinto efanelekileyo yokukhetha izicelo ezifuna i-welding. "L" kwi-316L imele "phantsi," ebonisa umxholo wekhabhoni oncitshisiweyo kwi-alloy. Olu phawu alugcini nje ukunyusa ukuwelda kwezinto kodwa lunciphisa umngcipheko wemvula ye-carbide kwiindawo ezichatshazelwe ngubushushu ngexesha le-welding, enokukhokelela kwi-corrosion ye-intergranular.
Enye yeempawu eziphambili ze-316L yensimbi engenasici kukumelana kwayo okungaqhelekanga nokugqwala, ngakumbi kwiindawo ezinobushushu obuphezulu. Oku kuyenza ibe lukhetho olugqwesileyo kwizicelo apho ukuba sesichengeni samaqondo obushushu anyukileyo kunye nezinto eziyingozi zekhemikhali ziyinkxalabo. Ikhono lezinto eziphathekayo zokumelana neemeko ezinzima ngolo hlobo ngaphandle kokuphazamisa ukuthembeka kwayo kwesakhiwo kububungqina bokusebenza kwayo okuphezulu.
Ngaphezu koko, i-316L yensimbi engenasici ithathwa kakhulu ngenxa ye-biocompatibility yayo, iyenza ibe yinto efanelekileyo yokufakelwa kwezonyango, ubucwebe bomzimba, kunye nezinye izicelo apho ukudibanisa nomzimba womntu kungenakuphepha. Isiqulatho sekhabhoni esezantsi kunye nokongezwa kwe-molybdenum kunegalelo ekuxhathiseni kwayo ukwazisa, ukunciphisa umngcipheko wokuchasana nokwaliwa kubantu abanovelwano kwiintsimbi ezithile. Le nto ye-biocompatibility igxininisa ngakumbi ukuguquguquka kunye nokhuseleko lwe-316L yensimbi engenasici kubathengi abahlukeneyo kunye nezicelo zonyango.
Ukongeza kwi-corrosion resistance and biocompatibility, i-316L yensimbi engenasici ibonisa ukuqina kunye nokuqina okungaqhelekanga. Ezi zakhiwo zenza ukuba zilungele uluhlu olubanzi lweemveliso kunye neemveliso zabathengi, kubandakanywa izixhobo zotyando, izixhobo zaselwandle, oomatshini bokulungisa ukutya, kunye namacandelo okwakha. Ikhono lezinto eziphathekayo lokumelana noxinzelelo lomatshini, impembelelo, kunye neemeko ezibuhlungu zokusingqongileyo kugxininisa ukuthembeka kwayo kunye nokuphila ixesha elide kwizicelo ezifunayo.
Xa kuziwa kwizicelo zemveliso, ukusebenza kwe-316L yensimbi engenasici kuphawuleka ngokukodwa kwiindawo ezinobushushu obuphezulu apho ukuxhathisa kwe-corrosion kubaluleke kakhulu. Ukukwazi kwayo ukugcina ingqibelelo yesakhiwo kunye nokuxhathisa i-oxidation kumaqondo aphakamileyo aphezulu kwenza kube yinto efanelekileyo yokutshintsha ubushushu, iinkqubo zokukhupha, izixhobo zomlilo, kunye nezinye izixhobo zoshishino ezisebenza phantsi kweemeko zokushisa okukhulu.
Isishwankathelo, i-316L insimbi engenasici yinto enika indibaniselwano ekhethekileyo yokumelana nobushushu obuphezulu bokushisa, ukuhambelana kwezinto eziphilayo, kunye nokuqina. Umxholo wayo ophantsi wekhabhoni, ukongezwa kwe-molybdenum, kunye nokwakheka kwe-alloy iyonke kunegalelo ekusebenzeni kwayo okukhethekileyo kwizicelo ezahlukeneyo. Nokuba ikwicandelo lezonyango, ishishini, okanye abathengi, i-316L insimbi engenasici iyaqhubeka ukuba yinto ekhethwayo kwiimveliso ezifuna ukuthembeka, ubomi obude kunye nokhuseleko.
