IBanga le-316 linqanaba eliqhelekileyo lokuthwala i-molybdenum, okwesibini ngokubaluleka ukuya kuma-304 phakathi kwe-austenitic stainless steels.I-molybdenum inika iipropati ezingama-316 ezingcono zokuxhathisa umhlwa kuneBanga lama-304, ngokukodwa ukuxhathisa okuphezulu kwimingxuma kunye nokuhlwa kwemingxuma kwiindawo ezinekloridi.
iStainless Steel – iBakala 316L – iiPropati, ukuFakwa kunye nezicelo (UNS S31603)
IBanga le-316L, i-carbon version ephantsi ye-316 kwaye ikhuselekile kwi-sensitization (i-grain boundary carbide precipitation).Ngaloo ndlela isetyenziswa kakhulu kwigeyiji enzima edityanisiweyo (ngaphezulu kwe-6mm).Ngokuqhelekileyo akukho mahluko axabisayo phakathi kwe-316 kunye ne-316L yensimbi engenasici.
Isakhiwo se-austenitic sikwanika la mabanga ukuqina okugqwesileyo, kude kube phantsi ukuya kumaqondo obushushu e-cryogenic.
Xa kuthelekiswa ne-chromium-nickel austenitic steel stainless steels, i-316L yensimbi engenasici inikezela ngokunyuka okuphezulu, uxinzelelo lokugqabhuka kunye namandla okuqina kumaqondo obushushu aphezulu.
Iimpawu eziphambili
iStainless Steel – iBakala 316L – iiPropati, ukuFakwa kunye nezicelo (UNS S31603)
Ezi zakhiwo zichazwe kwiimveliso eziqengqelekayo (ipleyiti, icwecwe, kunye nekhoyili) kwi-ASTM A240/A240M.Iipropati ezifanayo kodwa zingafane zichazwe kwezinye iimveliso ezinjengombhobho kunye nebar kwiinkcukacha zazo.
