2025-06-26
Chiyambi: Chitsulo chosapanga dzimbiri ndi chamtengo wapatali chifukwa cha kulimba kwake komanso kukana dzimbiri. Pakati pa masukulu ake ambiri, 316l Chitsulo chosapanga dzimbiri ndi aloyi wochepa wa carbon, austenitic alloy wamtengo wapatali chifukwa cha kukana kwa dzimbiri komanso kukhazikika kwa makina. Chitsulo ichi cha "marine-grade" chimakhala ndi molybdenum yowonjezera ndipo nthawi zambiri imagwiritsidwa ntchito pamene kukhazikika kumakhala kofunikira - kuchokera ku implants zachipatala kupita ku zipangizo zapamadzi. Pansipa timafotokoza mwatsatanetsatane kapangidwe ka mankhwala a 316L, ubwino woposa magiredi ena, komanso momwe amagwiritsidwira ntchito pamakampani ndi kupanga.
Mapangidwe ndi Zofunika Kwambiri
Mapangidwe a Chemical: Gulu 316L ndi aloyi yochokera kuchitsulo yokhala ndi pafupifupi 16-18% chromium, 10-14% nickel, ndi 2-3% molybdenum. (Ilinso ndi ~ 2% manganese ndi silicon pang'ono, phosphorous, ndi sulfure.) Zochepa za carbon (≤0.03%) zimasiyanitsa 316L ndi standard 316 (≤0.08%), kukonza weldability ndi kuchepetsa mpweya wa carbide.
Katundu Wathupi: Monga chitsulo chosapanga dzimbiri cha austenitic, 316L simaginito (mumalo opindika), yokhala ndi kachulukidwe pafupifupi 8.0 g/cm³. Imakhala ndi mphamvu zambiri pamitundu yosiyanasiyana ya kutentha. Mwachitsanzo, kulimba kwamphamvu kumakhala kawirikawiri 485-620 MPa, ndipo imakhalabe yolimba pa kutentha kwa cryogenic ndi kokwera. (Opanga nthawi zambiri amagwiritsa ntchito 316L mpaka pafupifupi 800 °C kapena kupitilira apo kuti asatenthedwe.)
Kulimbana ndi Corrosion: Kuphatikizika kwa chromium ndi molybdenum kumapereka 316L kukana kwambiri pobowola ndi dzimbiri m'malo okhala ndi chloride (monga madzi a m'nyanja). Kuwonjezeka kwa molybdenum kumapangitsa kuti ikhale yopambana kwambiri kuposa 304 yosapanga dzimbiri m'malo ankhanza monga kukonza zam'madzi kapena mankhwala.
Gulu la Mtundu: Martensitic vs. Austenitic
-
410 Chitsulo chosapanga dzimbiri (Martensitic) - Chitsulo chosapanga dzimbiri cha 400 chokhala ndi pafupifupi 12% chromium ndipo palibe faifi tambala. Ili ndi mawonekedwe a thupi la cubic (BCC), yomwe imapangitsa kuti ikhale maginito ndipo imalola kuumitsa ndi chithandizo cha kutentha. Zitsulo za Martensitic zimadziwika chifukwa champhamvu kwambiri komanso kukana kuvala zikapsa.
