Inconel 625 thiab 718 bolts: Qhov twg zoo dua rau koj daim ntawv thov?
Xaiv Inconel 625 bolts muab kev tiv thaiv corrosion zoo heev (rau seawater, acids, thiab tshuaj) thiab weldability zoo dua, ua rau lawv zoo tagnrho rau marine thiab tshuaj industries; xaiv Inconel 718 bolts muaj lub zog siab tshaj plaws thiab siab tshaj - qhov kub thiab txias tsis kam, zoo tshaj plaws rau aerospace, roj turbine, thiab siab - kev siv roj thiab roj uas muaj cov khoom siv hluav taws xob hnyav, vim tias 718 alloy yog nag lossis daus- tawv thiab tuaj yeem tiv taus huab cua.
Lub zog ntawm Inconel 718 bolts yog dab tsi?
185-220 hli
Inconel 718 yog ob zaug muaj zog li nws tus muam alloy, Inconel 625, thiab muaj npe nrov rau nws lub zog siab heev tom qab lub hnub nyoog tawv, nrog lub zog tensile txog li 185-220 ksi. Inconel 718 bolts tuav lawv lub zog txawm tias nyob rau hauv siab thiab kub siab txog 1300℃F (700 degree).
Inconel 625 bolts yog siab -kev ua tau zoo fasteners ua los ntawm Inconel 625 alloy. Lawv cov txiaj ntsig tseem ceeb yog nyob rau hauv kev nthuav dav thiab zoo dua corrosion tsis kam ntawm cov alloy, zoo tiv thaiv pitting corrosion, crevice corrosion, chloride stress corrosion cracking, thiab oxidation thiab txo cov acidic media. Lawv kuj muaj qhov zoo heev - qhov kub thiab txias zog (txog li 980 degree) thiab nkag siab tsis kam. Lawv tau tsim tshwj xeeb los muab cov kev daws teeb meem ruaj khov rau cov ntawv thov hauv huab cua corrosive thiab siab - qhov kub thiab txias ib puag ncig, xws li marine engineering, xav tau kev ua tshuaj lom neeg, flue gas desulfurization systems, thiab aerospace, ua rau lawv muaj kev sib txuas zoo dua nrog kev ua haujlwm dav thiab muaj zog dua li cov hlau tsis zoo tib yam bolts.
Inconel 718 bolts yog siab- lub zog fasteners ua los ntawm nag lossis daus-nickel hardened-chromium-raws li siab- kub alloy (Inconel 718). Lawv cov yam ntxwv tseem ceeb yog nag lossis daus ua tiav los ntawm cov ntsiab lus xws li niobium, tswj hwm ultra- lub zog siab, zoo heev creep tsis kam, thiab qaug zog tiv thaiv ntawm qhov kub txog li 700 degree, thaum tseem muaj cov corrosion kuj zoo. Lawv tau tsim tshwj xeeb rau cov ntawv thov tseem ceeb uas yuav tsum tau ua kom muaj kev ruaj ntseg xauv lub zog thaum muaj kev ntxhov siab, kub siab, thiab kev vibration hnyav, xws li hauv cov tshuab dav hlau, cov qauv hauv aerospace, roj thiab roj kev lag luam, thiab siab - kev ua tau zoo ntawm cov tsheb sib tw, ua rau lawv yog ib qho kev xaiv saum toj kawg nkaus -tier bolt xaiv rau qhov xav tau kev sib tw tshuab kev sib tw tshaj plaws.

Inconel 625 vs . 718 Bolts: Qhov twg yog qhov zoo tshaj rau koj daim ntawv thov?
Inconel fasteners feem ntau siv nyob rau hauv qhov chaw huab cua thiab muaj nyob rau hauv ob peb "qib" nyob ntawm daim ntawv thov. Tsab ntawv xov xwm no yuav qhia luv luv piv ob ntawm cov qib uas muaj ntau tshaj, Inconel 625 thiab Inconel 718, los pab koj xaiv cov khoom siv zoo tshaj plaws.
Qhov Tseem Ceeb Qhov txawv 625 vs . 718
Ib 625
• Zoo dua tag nrho corrosion kuj
• Ntev-lub sij hawm siab- kub stability
ib 718
• nag lossis daus hardened
• Ob zaug lub zog ntawm Inconel 625
Ib 625
Inconel 625 screws muaj ntau cov nickel, chromium, thiab molybdenum, ua rau lawv tsis tsuas yog muaj zog ntawm qhov kub thiab txias, tab sis kuj tiv taus corrosion, oxidation, thiab carburization. Ib qho ntawm nws cov yam ntxwv tseem ceeb tshaj plaws yog nws tsis kam tiv thaiv kev ntxhov siab corrosion, pitting, thiab crevice corrosion, txawm tias thaum raug chloride ions.
Qhov zoo
