Q1: Dab tsi yog cov tshuaj lom neeg muaj pes tsawg leeg ntawm S460NH cov yeeb nkab?
Cov tshuaj lom neeg muaj kuab lom ntawm S460NH steel yeeb nkab feem ntau suav nrog cov pa roj carbon (c) Cov pa roj carbon cov ntsiab lus yog feem ntau tswj tau hauv qab 0.20% kom ntseeg tau zoo weldability thiab tsawg} kub. Cov ntsiab lus manganese yog tus muaj siab (1.00% -1.60%) txhawm rau txhim kho lub zog thiab cov tawv nqaij tawv. Phosphorus thiab cov leeg sulfur cov ntsiab lus yuav tsum tau nruj me ntsis (p tsawg dua lossis sib npaug lossis 0.025%) kom txo qis txias brittleness thiab kub cracking. Tsis tas li ntawd, ntxiv mus ntxiv rau Niobium thiab Vanadium Refines cov noob nplej, txhim kho lub zog thiab tawv ntawm cov yeeb nkab steel.
Q2: Cov khoom siv neeg kho tshuab ntawm S460NH cov yeeb nkab? S460NH steel yeeb nkab muaj tsawg kawg vim muaj lub zog (RM) ntawm 460 MPa li ntawm 550} (5) ntawm tsawg kawg 17%. Qhov kev ua yeeb yam hlau no ua kom muaj kev cuam tshuam ntau rau qhov kev ua tau zoo, tswj cov kev ua tau zoo txawm tias tsis kub (-50 degree). Nws brinell hardness (HBW) feem ntau yog li 170-220, ua rau nws haum rau cov khoom siv hluav taws xob siab. Nws cov cuab yeej siv tau ruaj khov ua rau nws dav siv hauv cov choj, cov tuam tsev, thiab tshuab hnyav.
Q3: Muaj ib puag ncig ib puag ncig haum rau s460NH cov yeeb nkab?
S460NH steel yeeb nkab yog qhov haum rau qis - kub, thiab cov qauv kev ntxhov siab nyob rau hauv cov cheeb tsam txias lossis cov cua tshuab hluav taws xob txhawb nqa. Nws cov huab cua ua hauj lwm tshaj plaws uas yog cov pa roj carbon hlau, tswj kev ua tau zoo hauv qhov kub thiab txias nyob rau {{8 Qib rau {{5} degree. Qhov txheej txheem hlau no kuj tseem ua pov hwm qee qhov kev tiv thaiv corrosion, tab sis tseem yuav tsum tau sib tiv thaiv ntawm cov chaw muaj huab cua lossis lub cev. Tsis tas li ntawd, nws lub zog siab thiab zoo heev veldability ua rau nws haum rau av qeeg {{ove} Cov qauv tsim hauv av qeeg.
Q4: Dab tsi yog qhov sib txawv ntawm S460NH Steel Yeeb thiab lwm yam siab- lub zog hlau (xws li S355 thiab S690)?
S460NH cov txiaj ntsig lub zog (460 MPA) yog siab dua li ntawm S690 (690 MPa), ua rau nws nruab nrab {{{}} lub zog steel. Piv rau S355, S460NH muaj cov ntsiab lus ntau dua, tshwj xeeb manganese thiab microalloying ntsiab (nb thiab v) {{{{} kub todlight. S690, ntawm qhov tod tes, yuav tsum muaj ntau txoj kev kho tshav kub kub (xws li quenching thiab tempering), ua rau muaj nqi siab dua. S460NH tawm qhov sib npaug zoo ntawm Weldability thiab tus nqi- ua tau zoo, ua rau nws hnyav {17} Lub luag haujlwm.
Q5: Cov thawj cov yeeb nkab yog dab tsi?
Thawj cov qauv rau S460NH cov yeeb nkab yog EN 10219 (txias {{2} Hlub welded steel yeeb (}} mive welded steel yeeb nkab) hauv Tebchaws Europe. Nws kuj tseem tuaj yeem ua raws li ISO 630 cov qauv ntawm cov qauv lossis cov qhua tuaj noj mov - Cov Lus Pom Zoo Teadic. Cov qauv no qhia meej lawv cov tshuaj muaj pes tsawg leeg, cov khoom siv neeg siv tshuab, muaj kev nkag siab ntev, thiab cov qauv ntsuas. Thaum kev yuav khoom, nws yog ib qho tseem ceeb kom qhia tus qauv txheem (piv txwv li, en 10219-1: 2006) kom ntseeg tau tias cov ntaub ntawv ua raws.
