Stainless hlau bolts (304/316L) yog cov feem ntau fasteners rau kev lag luam kev siv vim lawv cov nqi -kev ua tau zoo thiab ruaj khov kev ua tau zoo. Txawm li cas los xij, nyob rau hauv ib puag ncig hnyav, siab - khoom siv precision, thiab lub teeb yuag - kev lag luam rhiab heev, stainless hlau fasteners inevitably raug kev txom nyem los ntawm pitting corrosion, hnyav hnyav, sib nqus cuam tshuam, thiab lub neej luv luv. Titanium bolts (Qib 2 ntshiab titanium & Qib 5 titanium alloy) tau dhau los ua qhov kev txhim kho zoo tshaj plaws, daws cov ntsiab lus mob ntawm stainless hlau fasteners hauv siab -xov xwm scenarios.
Titanium Bolt vs Stainless hlau Bolt
Corrosion kuj: Titanium resists seawater thiab chloride corrosion mus tas li; 316L stainless hlau tseem rusts nyob rau hauv hnyav ntsev pos huab.
Qhov hnyav: Titanium yog 40% sib dua dua stainless hlau, zoo tagnrho rau kev hloov khoom dua tshiab.
Cov khoom sib nqus: Titanium yog kiag li tsis yog -magnetic; stainless hlau muaj residual hlau nplaum.
Kev pab lub neej: Titanium bolts muaj 3-5 lub sij hawm ntev kev pab cuam lub neej tshaj stainless hlau nyob rau hauv huab ib puag ncig, txo nqi txij nkawm.
316L stainless hlau, hu ua marine- qib stainless hlau, tseem tsis tuaj yeem tiv taus ntev - lub sij hawm yaig los ntawm dej hiav txwv, chloride ions, thiab ntug hiav txwv ntsev pos huab. Nws yooj yim rau pitting corrosion, crevice corrosion, thiab xeb creeping, ua rau fastener loosening, aging, thiab cov khoom tsis ua hauj lwm.
Titanium bolts rely on a dense, self-healing TiO₂ passive film, showing almost zero corrosion rate in seawater and high-chloride environments. Lawv yuav tsum tsis txhob hloov ntau zaus thiab txo cov nqi txij nkawm tom qab.
Austenitic stainless hlau khaws cov hlau nplaum tsis muaj zog tom qab ua tiav thiab kev vibration, uas cuam tshuam nrog siab - precision magnetic test, kev kho mob, thiab cov khoom siv electromagnetic. Titanium yog kiag li tsis yog- sib nqus uas tsis muaj kev cuam tshuam sib nqus ntawm txhua qhov, ua rau nws yog ib qho khoom siv tsis tuaj yeem hloov tau rau cov hlau nplaum- qhov xwm txheej ceev.
Stainless hlau fasteners muaj nickel Cheebtsam, uas tej zaum yuav precipitate ions thiab ua rau muaj kev tsis haum tshuaj los yog cov ntaub so ntswg irritation tom qab ntev - mus cuag tib neeg daim tawv nqaij thiab cov ntaub so ntswg. Titanium muaj biocompatibility zoo heev, tsis yog - toxicity, thiab tsis muaj kev tsis lees paub, ua raws li kev kho mob qib - cov qauv kev nyab xeeb.
Nyob rau hauv kev ua hauj lwm ntawm nitric acid, organic acid, qaug zog alkali tov, thiab tshuaj fermentation ib puag ncig, stainless hlau yog nquag rau tshuaj corrosion thiab nto oxidation. Titanium tuav ruaj khov ua yeeb yaj kiab ua haujlwm ntev ntev, tiv thaiv cov tshuaj lom neeg nruab nrab thiab tsis txhob cuam tshuam kev ua haujlwm tsis zoo thiab muaj kuab paug.
Stainless hlau yuav muaj qhov pom tseeb lub zog attenuation thiab nto oxidation aging nyob rau hauv ntev -lub sij hawm tsis tu ncua kub kub (tsawg dua los yog sib npaug rau 300 degree) thiab ultra- qhov kub thiab txias ib puag ncig. Titanium bolts feature ruaj khov txhua yam khoom nyob rau hauv thaj tsam ntawm -196℃mus rau 300 degree, zoo heev qaug zog thiab thermal stability, haum rau huab cua kub mus ua hauj lwm tej yam kev mob.
