1. Cov Khoom Siv Hluav Taws Xob thiab Lawv Cov Khoom Tseem Ceeb - Cov Khoom Siv Hluav Taws Xob Cov Hluav Taws Xob: Tus nqi- siv tau, siab tensile lub zog (nyob ntawm qib), yooj yim rau tshuab thiab cua sov- kho. Txawm li cas los xij, kev tiv thaiv corrosion tsis zoo- nws yooj yim rau xeb hauv qhov chaw ntub lossis sab nraum zoov. Cov qib muaj xws li qis- carbon steel (qib 2, haum rau lub teeb loads) thiab siab - carbon steel (qib 8, siab{11}}lub zog rau hnyav loads). Cov ntawv thov zoo tshaj plaws: General-lub hom phiaj siv sab hauv tsev xws li rooj tog sib dhos, cov qauv hlau me me, thiab tsis yog{14}} cov tshuab tseem ceeb. High- carbon steel fasteners (qib 8) kuj tseem siv rau hauv tsheb cav thiab cov cuab yeej hnyav uas lub zog yog qhov tseem ceeb tshaj qhov kev tiv thaiv corrosion (feem ntau nrog cov txheej txheej rau kev tiv thaiv yooj yim). - Stainless Steel Key Properties: Zoo heev corrosion kuj vim muaj chromium oxide passive txheej ntawm qhov chaw. Lub zog zoo, ductility, thiab tu cev (tsis yog - lom, yooj yim los ntxuav). Cov qib muaj xws li 304 (18-8 stainless hlau, dav- lub hom phiaj) thiab 316 (marine- qib, nrog molybdenum rau txhim kho corrosion tiv thaiv dej ntsev thiab tshuaj). Cov Khoom Siv Zoo Tshaj Plaws: Cov qauv sab nrauv, cov khoom siv hauv hiav txwv (nkoj, ntug dej hiav txwv), cov khoom siv ua zaub mov, cov khoom siv kho mob, thiab cov chaw ntug dej hiav txwv lossis qhov chaw ntub dej . 304 stainless hlau yog haum rau feem ntau corrosive -dawb los yog me me corrosive scenarios, thaum 316 yog nyiam rau cov dej ntsev, tshuaj nroj tsuag, thiab hnyav heev ib puag ncig{35} (li 1/3 qhov ceev ntawm cov hlau), zoo thermal thiab hluav taws xob conductivity, nruab nrab corrosion kuj (tsim ib tug natural oxide txheej). Lub zog tensile qis dua hlau, yog li tsis haum rau siab -load daim ntawv thov. Cov Kev Siv Zoo Tshaj Plaws: Cov khoom siv dav hlau (kom txo qhov hnyav), cov khoom siv hauv lub cev, cov khoom siv hluav taws xob, thiab cov kev siv qhov kev txo qhov hnyav yog qhov tseem ceeb (xws li, cov qauv txhuas, lub teeb yuag machinery). Feem ntau siv nrog cov khoom sib xws (anodizing) txhawm rau txhim kho hnav tsis kam. - Cov Khoom Siv Hluav Taws Xob: Cov khoom siv hluav taws xob zoo heev, zoo corrosion kuj (tshwj xeeb tshaj yog tiv thaiv tsis yog -} oxidizing acids), zoo nkauj golden, thiab yooj yim rau tshuab. Lub zog nruab nrab, softer dua hlau thiab stainless hlau. Cov Khoom Siv Zoo Tshaj Plaws: Cov khoom siv hluav taws xob thiab hluav taws xob (xws li, cov ntsia hlau davhlau ya nyob twg, Circuit Court board fasteners), cov kav dej (cov kav dej, li qub), cov khoom siv kho kom zoo nkauj (cov rooj tog zaum, cov ntsiab lus ntawm cov vaj tsev), thiab cov ntawv thov hauv hiav txwv uas xav tau hluav taws xob conductivity thiab corrosion kuj yog qhov xav tau. - Titanium Key Properties: Exceptionally siab zog {{51}, tab sis zoo heev corrosion ({51}) tsis kam (tiv taus tshuaj feem ntau, dej ntsev, thiab kub), thiab biocompatibility (muaj kev nyab xeeb rau tib neeg kev sib cuag). Txawm li cas los xij, nws yog kim thiab nyuaj rau tshuab. Cov Kev Siv Zoo Tshaj Plaws: Aerospace thiab aviation (aircraft engines, fuselage components), kho mob implants (ntsia hlau rau pob txha fixation), siab -kev ua tau zoo sib tw tsheb, thiab huab ib puag ncig (siab-kub industrial furnaces, tob- hiav txwv khoom) . 2. Cov khoom tseem ceeb . 2. Cov khoom tseem ceeb Txheeb xyuas qhov raug dej noo, ntsev, tshuaj lom neeg, thiab kub hloov pauv. Piv txwv li, siv 316 stainless hlau lossis titanium hauv dej ntsev; carbon steel nrog zinc plating rau hauv tsev qhuav ib puag ncig. - Load Requirements: High-load applications (xws li, heavy machinery, structural steel) xav tau siab-cov ntaub ntawv muaj zog xws li qib 8 carbon steel lossis titanium. Lub teeb-load daim ntawv thov (xws li, hluav taws xob, rooj tog) tuaj yeem siv txhuas, tooj dag, lossis cov pa roj carbon tsawg. - Cov nqi txwv: Cov pa roj carbon steel yog qhov kev xaiv pheej yig tshaj plaws rau kev siv dav dav. Stainless hlau, txhuas, thiab tooj dag yog tus nqi nruab nrab, thaum titanium yog qhov kev xaiv zoo tshaj rau cov ntawv tshwj xeeb. - Cov Kev Xav Tau Tshwj Xeeb: Biocompatibility (kev kho mob cog) hu rau titanium lossis 316L stainless hlau; hluav taws xob conductivity (electronics) nyiam tooj dag lossis tooj liab fasteners.
Key Takeaway: Sib piv cov khoom siv fastener rau daim ntawv thov qhov chaw ib puag ncig, kev xav tau ntawm kev thauj khoom, thiab cov nqi siv nyiaj yog qhov tseem ceeb. Cov pa roj carbon steel ua haujlwm rau kev siv sab hauv tsev, stainless hlau rau corrosive ib puag ncig, aluminium rau lub teeb yuag xav tau, tooj dag rau hluav taws xob thiab kho kom zoo nkauj daim ntawv thov, thiab titanium rau siab - kev ua tau zoo lossis xwm txheej hnyav.
