2025-06-26
Intshayelelo: Insimbi engenasici ixabiswa ngokuhlala kwayo kunye nokuxhathisa ukubola. Phakathi kwamanqaku ayo amaninzi, 316l iNtsimbi engatyiwa yikhabhoni ephantsi, iaustenitic alloy exabiseke kakhulu ngenxa yokumelana nomhlwa okungaqhelekanga kunye nokuzinza koomatshini. Le nsimbi "yenqanaba lolwandle" iqulethe i-molybdenum eyongezelelweyo kwaye isetyenziswa rhoqo apho ukuqina kubaluleke kakhulu - ukusuka kukufakelwa kwezonyango kwizixhobo zaselwandle. Apha ngezantsi sichaza i-316L yokwenziwa kweekhemikhali, izibonelelo ngaphezu kwamanye amabanga, kunye nokusetyenziswa kwayo okuqhelekileyo kushishino kunye nemveliso.
Ukubunjwa kunye neePropati eziPhambili
Ukuqulunqwa kwemichiza: IBakala 316L yintsimbi esekwe kwialloyi erhabaxa 16–18% chromium, 10–14% nickel, kunye 2–3% molybdenum. (Kwakhona iqulethe i- ~ 2% ye-manganese kunye neemali ezincinci ze-silicon, i-phosphorus, kunye ne-sulfure.) Umxholo wekhabhoni ephantsi (≤0.03%) uhlukanisa i-316L ukusuka kwi-316 eqhelekileyo (≤0.08%), ukuphucula i-weldability kunye nokunciphisa imvula ye-carbide.
Iinkcazelo Ngeempawu: Njengentsimbi ye-austenitic stainless, i-316L ayiyo-magnetic (kwimeko efakwe kwi-annealed), kunye noxinano malunga ne-8.0 g/cm³. Igcina amandla aphezulu kuluhlu olubanzi lobushushu. Umzekelo, amandla okuqina aqhelekile 485–620 MPa, kwaye ihlala inzima kwi-cryogenic kunye neqondo lokushisa eliphakamileyo. (Abavelisi bahlala besebenzisa i-316L ukuya kuthi ga kwi-800 °C okanye ngaphezulu ukuxhathisa ubushushu.)
Ukuxhathisa ukonakala: Indibaniselwano yechromium kunye ne-molybdenum inika i-316L ukuxhathisa okugqwesileyo kwimingxuma kunye nokuhlwa kwemingxuma kwiindawo ezityebileyo ngechloride (umz. amanzi olwandle). Ukunyuswa kwemolybdenum kuyenza iphakame kakhulu kuma-304 ngaphandle kwebala kwiindawo ezinobundlongondlongo ezifana nolwandle okanye ukusetyenzwa kweekhemikhali.
Uhlobo loHlelo: Martensitic vs. Austenitic
-
