Vim li cas ho xaiv stainless hlau ASTM A193 B8 Stud bolts thiab A 194 8 txiv ntseej?
Kev xaiv ntawm stainless hlau ASTM A193 B8 Stud bolts thiab A 194 8 txiv ntseej yog tsim los ntawm lawv cov corrosion kuj zoo heev, siab zog, thiab ntev - kev lag luam, tshwj xeeb tshaj yog haum rau cov cheeb tsam hnyav. Cov hauv qab no yog cov ntsiab lus ntawm cov laj thawj tseem ceeb:
Excellent corrosion resistance: Stainless steel (such as 304 or 316 models) can form a dense chromium oxide passivation film on its surface, effectively resisting corrosive media such as moisture and salt spray. Nyob rau hauv ntug dej hiav txwv los yog tshuaj lom neeg ib puag ncig, nws corrosion kuj lub neej nyob deb tshaj li cov carbon steel bolts zoo tib yam. Piv txwv li, 304 stainless hlau tuaj yeem tiv taus 500-800 teev yam tsis muaj xeb liab hauv kev kuaj ntsev ntsev, thaum carbon steel bolts tuaj yeem ua tsis tiav hauv 30 hnub. cov
Lub zog siab thiab kev ntseeg siab: Stainless hlau ASTM A193 B8 Stud bolts thiab A 194 8 txiv ntseej muaj lub zog tensile siab (xws li 304 stainless hlau Ntau dua los yog sib npaug rau 515MPa) thiab qaug zog zog (txog 240MPa lossis ntau dua), thiab thaum ua ke nrog ob lub taub hau tsim, tuaj yeem ua tiav kev sib npaug ntawm kev quab yuam. Qhov no ua rau nws ruaj khov hauv kev thauj khoom-cov kabmob xws li txuas txuas thiab cov kav hlau txais xov, thiab tseem txo qhov kev hloov pauv los ntawm 23% hauv kev simulated av qeeg. cov
Lub sij hawm ntev kev lag luam kom zoo dua: Txawm hais tias tus nqi pib ntawm cov khoom siv yog kwv yees li 35% siab dua cov pa roj carbon steel, qhov kev saib xyuas tsis pub muaj qhov txo qis tag nrho cov nqi ntawm lub neej. Piv txwv li, dhau 20-xyoo lub neej, kev tiv thaiv- cov nqi kho corrosion tuaj yeem txuag tau ntau dua 60%, thiab kev poob qis los ntawm kev hloov pauv tuaj yeem zam tau. Tus nqi tag nrho yuav qis dua qhov kub-dip galvanized carbon steel bolts. cov
Haum rau qhov chaw tshwj xeeb: Hauv cov chaw ntug dej hiav txwv, dej hiav txwv, lossis thaj chaw muaj av noo, chloride ions tuaj yeem yooj yim ua rau corrosion ntawm cov hlau, thaum stainless hlau ASTM A193 B8 Stud bolts thiab A194 8 txiv ntseej (tshwj xeeb tshaj yog 316 qauv uas muaj molybdenum) tuaj yeem tiv taus pitting thiab crevice corrosion. Cov xwm txheej tiag tiag tau pom tias cov khoom siv tsis ua haujlwm ntawm Xiamen Chaw nres nkoj tau txo qis los ntawm 60% tom qab siv stainless hlau bolts. cov
Kev txhim kho thiab kev saib xyuas yooj yim: Kev tsim ob lub taub hau ua kom yooj yim symmetrical fastening, txo cov teeb meem kev teeb tsa; Cov txheej txheej saum npoo (xws li molybdenum disulfide) tuaj yeem txo qhov coefficient ntawm kev sib txhuam thiab ua kom muaj kev tswj xyuas ntau dua ntawm preload quab yuam. Nyob rau tib lub sijhawm, nws cov kev tiv thaiv corrosion zam qhov nyuaj ntawm kev sib tsoo los ntawm xeb, ua rau nws tsim nyog rau cov xwm txheej uas yuav tsum tau saib xyuas tas li. cov
Thaum xaiv, nws yog ib qho tsim nyog yuav tau xav txog qhov tshwj xeeb ib puag ncig: 304 stainless hlau tuaj yeem xaiv rau qhov chaw zoo tib yam ntsev tsuag, thiab 316 qauv raug pom zoo rau kev muaj zog corrosion los yog kev sib cuag nrog seawater scenarios kom sib npaug kev ua tau zoo thiab tus nqi.
