Sus 316 yog kev tsim qauv rau ib hom steel tshwj xeeb, nrog nws cov hauv paus hniav hauv Japanese muaj cov qauv kev lag luam. Lo lus "sus" keeb kwm los ntawm Japanese kev lag luam qauv (JIS) thiab yog cov lus luv) thiab yog cov tsiaj ntawv luv ntawm "steel siv stainless hlau cov khoom siv rau kev siv cov ntawv thov. Tus lej "316" yog cov cim qhia thoob ntiaj teb uas ua kom haum rau cov hoob kawm hauv 316 hauv Asmeskas haiv neeg thiab cov qauv zoo sib xws rau lub ntiaj teb. Ua ke, "Sus 316" yog hais txog molybdenum -} muaj cov tshuaj tiv thaiv corrosion uas muaj kev xaiv corrosion tsis kam, ua rau nws xaiv qhov chaw xav tau.
Tub ntxhais muaj pes tsawg leeg ntawm sus 316
Sus 316 txhais tau los ntawm nws cov qauv tshuaj muaj pes tsawg leeg, uas ncaj qha txhawb rau nws txoj kev ua tau zoo:
Chromium (16-18%): Ua ib txheej oxide passive rau saum npoo av, tiv thaiv xeb thiab xeb thiab xeb.
Nickel (10-14%): Txav ruaj khov Crystal Crystal Crystal, txhim kho kev txhim kho thiab tawv me me, tshwj xeeb yog qhov kub tsawg.
Molybdenum (2-3%): Ib qho tseem ceeb sib txawv ntawm lwm tus hlau tsis xws li tau 304. Molybdenum kev nplua nuj xws li muaj dej hiav txwv lossis dej hiav txwv.
Hlau (sib npaug): Lub hauv paus hlau muab lub zog txheej txheem.
Lwm cov ntsiab lus: Cov pa roj carbon ntau: Max 0.08%), mana 2.0%), thiab phosphorus (Max 0.}
Qhov kev sib xyaw no ua kom ntseeg tau tias muaj ntau yam cov hlau tsis muaj zog hauv cov khoom siv hnyav, ua rau nws muaj kev cuam tshuam nrog cov yam ntxwv ua tib zoo nrog cov yam ntxwv ua haujlwm.
Vim li cas Sus 316 teeb meem: kev ua tau zoo thiab zoo
Tshaj li kev faib tawm, sus 316 yog muaj nuj nqis rau nws cov kev sib xyaw ua ke ntawm cov yam ntxwv, uas kav ncaj qha los ntawm nws cov lus sib xyaw:
Zoo tshaj corrosion Kuj: ntxiv rau ntawm molybdenum ua rau nws muaj kev tiv thaiv zoo rau kev tawm tsam los ntawm cov kua qaub, ntsev, thiab kev lag luam tshuaj. Nws yog ua tau zoo nyob rau hauv cov chaw nyob ib puag ncig nrog cov khoom lag luam chloride, cov khoom siv hiav txwv, thiab siv cov khoom siv tshuaj tsw qab 304
Siab - kub ruaj khov: nws khaws lub zog thiab oxidation tiv taus kub (txog li kev siv hluav taws xob lossis cov pa tawm.
Mechanical zog: nws muaj cov zog zoo (yam tsawg kawg nkaus 515 MPa) thiab ductility, tso cai rau kev sib sau, thiab kev sib tw ua ke tsis muaj kev ncaj ncees.
Biocompatibility: nws tsis kam rau corrosion thiab tsis - reactivity ua rau nws haum rau cov cuab yeej kho mob, xws li kev pom zoo cov cuab yeej thiab kev pom.
Cov kev siv ntawm Sus 316
Qhov "Sus 316" tau lees paub txog kev lag luam uas cov kev ntseeg tau yooj yim. Raug siv suav nrog:
Marine Engineering: Nkoj Hulls, Propellers Rig Cov Khoom Siv Rig, qhov twg yog mus rau Saltwater cov kev xav tau tshwj xeeb corrosion.
Tshuaj lom neeg: kav dej, tso tsheb hlau luam, thiab li qub siv los thauj khoom lossis khaws cov kua qaub, thiab cov tshuaj ntsuab.
Cov khoom noj thiab khoom siv khoom noj khoom haus thiab cov tshuab siv khoom noj khoom haus: tshuab rau kev ua zaub mov, thiab siv yeeb siv tshuaj, vim nws yooj yim los ntxuav.
Cov Khoom Siv Kho Mob
Sab nraum zoov thiab Architectural vaj tse: cov ntug dej hiav txwv, sab nraum zoov cov ntsiab lus, thiab zoo nkauj cov ntsiab lus uas yuav tsum tiv thaiv kom los nag, ntsev thiab av noo.
Hauv cov ntsiab lus, "Sus 316" yog ntau tshaj qhov chaws - Nws sawv cev rau lub siab {2} Kev ua tau zoo rau ib puag ncig nyuaj. Nws cov qauv tsim kev sib koom tes Japanese faib tawm (sus) nrog rau kev nkag siab thoob ntiaj teb (316), ua rau muaj kev nkag siab thoob ntiaj teb thiab kev ntseeg tau, thiab cov ntawv thov kev kho mob, thiab cov neeg siv khoom. Thaum xaiv cov ntaub ntawv rau cov phiaj xwm corrosion tsis kam, lub zog, lossis biocompatibility, sus 316 tseem yog qhov xaiv cov cim.
