A2-70 yog dab tsi?
Dab tsi yog A2-70 ua los ntawm yog ib lo lus nug tshwm sim hauv kev lag luam tshuaj thiab hauv cov fasteners. Kev nkag siab txog cov khoom siv, cov khoom thiab cov ntawv thov ntawm A2-70 yog qhov tseem ceeb los xyuas kom meej qhov ua tiav ntawm koj qhov project. Hauv tsab xov xwm no, peb yuav muab cov ncauj lus kom ntxaws txog cov ntsiab lus ntawm cov khoom siv, muaj pes tsawg leeg, thiab cov khoom ntawm A2-70 thiab nws cov ntawv thov hauv ntau qhov kev lag luam.
Lub ntsiab txhais ntawm A2-70 Khoom
A2-70 yog hais txog ib qho tshwj xeeb ntawm austenitic stainless hlau uas feem ntau siv rau hauv fasteners xws li bolts, ceev thiab screws.A2 stands rau hom khoom, thaum 70 qhia nws tensile lub zog ntsuas. Tshwj xeeb, cov khoom siv A2-70 ua raws li ISO 3506 tus qauv thoob ntiaj teb rau qib stainless hlau, thiab muaj cov khoom zoo heev tshwj xeeb tshaj yog nyob rau hauv cov nqe lus ntawm corrosion resistance thiab mechanical zog.
Tshuaj muaj pes tsawg leeg ntawm A2-70
A2-70 cov khoom poob rau hauv qeb ntawm 304 stainless hlau, nrog rau cov khoom tseem ceeb xws li hlau, chromium (18%), npib tsib xee (8%), thiab cov pa roj carbon tsawg (siab tshaj 0.08%). Cov tshuaj muaj pes tsawg leeg ntawm no alloy muab nws zoo corrosion kuj thiab txhua yam muaj zog. Tshwj xeeb, qhov sib ntxiv ntawm chromium tsim cov yeeb yaj kiab tiv thaiv ntom ntom ntawm chromium oxide, uas zoo tiv thaiv oxidation thiab corrosion. Cov nickel tivthaiv, ntawm qhov tod tes, ua kom cov ductility thiab toughness ntawm cov khoom, ntxiv dag zog rau nws lub peev xwm los siv nyob rau hauv hnyav ib puag ncig.
Mechanical Properties ntawm A2-70
Cov khoom siv tshuab yog qhov tseem ceeb hauv kev nkag siab txog dab tsi A2-70 yog ua los ntawm, raws li A2-70 muaj lub zog tensile tsawg kawg yog 700 MPa, uas yog qhov "70" los ntawm. Tsis tas li ntawd, A2-70 muaj qhov zoo shear resistance, ductility thiab qaug zog.
Cov chaw thov rau A2-70 cov ntaub ntawv
Vim nws zoo heev corrosion kuj thiab mechanical zog, A2-70 khoom siv nyob rau hauv ib tug ntau yam ntawm industries, tshwj xeeb tshaj yog nyob rau hauv cov tshuaj, marine, kev tsim kho thiab zaub mov sectors. Hauv kev lag luam tshuaj, A2-70 feem ntau yog siv rau hauv cov khoom siv thiab cov kav dej uas yuav tsum tau ua rau cov tshuaj corrosive. Qhov kev tiv thaiv corrosion ntawm A2-70 kuj tseem ceeb tshwj xeeb hauv cov dej hiav txwv ib puag ncig, ua rau nws tsim nyog siv rau hauv nkoj tsim, offshore roj platforms, thiab lwm yam kev siv uas xav tau kev tiv thaiv dej hiav txwv corrosion.
Qhov zoo thiab qhov tsis zoo ntawm A2-70 cov khoom tsom xam
Piv nrog rau lwm cov ntaub ntawv stainless hlau, A2-70 muaj ntau yam zoo, xws li zoo corrosion kuj, siab mechanical zog thiab ntau yam kev siv. Nws kuj muaj qee qhov kev txwv.A2-70 tsis haum rau kev siv hauv ib puag ncig uas muaj cov tshuaj chloride ions siab, vim qhov no yuav ua rau pitting corrosion. Nws muaj qhov tsis zoo ntawm qhov kub thiab txias tsis zoo thiab tsis haum rau siv nyob rau hauv qhov kub thiab txias ib puag ncig.
Cov ntsiab lus
Cov lus teb rau lo lus nug ntawm dab tsi yog A2-70 ua los ntawm yog A2-70 yog cov khoom siv austenitic stainless hlau raws li 304 stainless hlau, uas muaj kev tiv thaiv corrosion zoo thiab txhua yam muaj zog, thiab tau siv dav hauv ntau qhov chaw xws li tshuaj lom neeg kev lag luam, marine, thiab kev tsim kho. Nkag siab txog cov khoom siv thiab cov xwm txheej ntawm daim ntawv thov ntawm A2-70 pab ua kom paub ntau ntxiv txog kev xaiv cov khoom siv hauv engineering.
Los ntawm kev qhia txog kab lus no, kuv ntseeg tias koj muaj kev nkag siab ntau ntxiv ntawm A2-70 cov ntaub ntawv, uas muab cov ntaub ntawv tseem ceeb rau kev txiav txim siab ua haujlwm yav tom ntej.
