ASTM A519 Qib 6150 Tubing hauv luv luv
Qib 6150 yog chromium -vanadium alloy steel hauv ASTM A519 seamless mechanical tubing tsev neeg. Nws cov ntsiab lus ntawm cov pa roj carbon ntau txaus los teb cov lus teb rau quenching, cov chromium txhawb nqa hardenability, thiab vanadium tsim cov carbides ruaj khov uas txwv tsis pub cov qoob loo loj hlob thaum lub sij hawm austenitizing. Qhov kev sib xyaw ua ke no ua rau cov khoom siv nrog qhov tsis sib xws siab elastic txwv thiab zoo heev tiv thaiv kev qaug zog thiab poob ntawm kev thauj khoom hauv qab kev ntxhov siab. Qib yog qhov kev xaiv classic rau lub caij nplooj ntoos hlav-zoo li cov khoom tsim los ua lub raj lossis bar, thiab nws kuj yog siv rau cov cuab yeej thiab tshuab cov ntsiab lus uas yuav tsum khaws lawv qhov ntev thaum ua haujlwm hauv kev vibration.
Vim hais tias austenitizing kub tswj yog ib qho tseem ceeb rau grain loj nyob rau hauv ib tug vanadium - bearing steel, 6150 yog ib txwm yuav nyob rau hauv lub quenched thiab tempered mob, nrog lub zeb qhia hardness thiab, thaum thov, tensile zog.

Muab quenched thiab tempered, tubing ntawm qib no feem ntau ncav cuag lub zog tensile ntawm 1200 mus rau 1500 MPa nrog elongation ntawm li 10% los yog ntau tshaj, thiab hardness nyob rau hauv qhov ntau ntawm HRC 45 mus rau 52 thaum ib feem yog austempered mus rau ib tug bainitic qauv es tsis txhob ntawm quenched nyob rau hauv txoj kev thiab tempered. Elastic modulus tseem nyob ib puag ncig ze 205 GPa tsis hais txog ntawm qhov cua sov- txoj kev kho mob, yog li qhov tawv nqaij raug teeb tsa los ntawm ntu, tsis yog los ntawm kev kho mob. Qhov twg qaug zog lub neej tswj hwm, qhov chaw saum npoo tseem ceeb tshaj qhov kev nce ntxiv hauv cov tub ntxhais lub zog: decarburization, sib tsoo kub hnyiab thiab cov khoom siv ua haujlwm ua haujlwm tawg thiab yuav tsum tau tswj hwm los ntawm kev txwv tshwj xeeb thiab kev tshuaj xyuas.
Tej kev siv
Ncua torsion bars, stabilizer tuav thiab coil caij nplooj ntoos hlav ntsiab rau tsheb thiab cov khoom siv rail.
Valve springs thiab springs -loaded damping Cheebtsam hauv cav thiab compressors.
Cov cuab yeej siv roj av xws li lub thawv ntim khoom thiab hnyav- lub luag haujlwm valve springs, qhov twg cuam tshuam thiab kev co ua ke.
Diaphragm springs thiab load hlwb nyob rau hauv precision instruments, qhov twg ib tug ruaj khov elastic txwv yog qhov tseem ceeb.
Cov cuab yeej tuav, chuck puab tsaig thiab siab -load clamping ntsiab.
Kev kho cua sov thiab kev ua haujlwm
Austenitize ntawm 850 txog 880 degree. Cov ntsiab lus vanadium nce qhov kub thiab txias uas xav tau rau kev daws cov carbides kom tiav, yog li cov dej ntub dej yuav tsum tau ntev txaus kom yaj lawv yam tsis pub cov qoob loo loj hlob; qhov ntsuas kub me ntsis nrog qhov tuav ntev dua yog qhov muaj kev nyab xeeb dua li qhov kub, lub voj voog luv. Roj los yog polymer quench, los yog austemper nyob rau hauv ib tug ntsev da dej rau cov seem tuab, uas yuav txo tau distortion thiab cracking txaus ntshai. Kub ntawm 400 thiab 500℃rau lub caij nplooj ntoos hlav; tuav txog li ob teev ntawm 450℃yog qhov pib pib rau lub caij nplooj ntoo hlav, thiab qhov kawg qhov tseem ceeb yuav tsum tau lees paub los ntawm kev sim ntawm qhov tseeb ntawm qhov cub. Loj - txoj kab uas hla lossis hnyav- cov hlab ntsa tau txais txiaj ntsig los ntawm cov txheej txheem quench kom ua kom cov thermal gradients nyob rau hauv kev sib tsoo ntawm cov hlau.
Kev tsim thiab machining yuav tsum tau ua ua ntej hardening qhov twg los tau. Yog tias yuav tsum tau vuam, preheat rau 300 txog 350 degree, siv qis -hydrogen consumable, thiab kev ntxhov siab-relieve ntawm li 620℃tom qab vuam, nrog rau soak scaled rau seem thickness. Tsis txhob cia lub welded los ua ke kom txias qeeb los ntawm 350 txog 550℃ntau yam.
Kev soj ntsuam thiab tuav cov ntsiab lus
Rau kev qaug zog- cov hlab ntsha tseem ceeb, qhia cov kev txwv ntawm decarburization saum npoo thiab xav tau cov khoom sib nqus los yog eddy tam sim no kuaj ntawm qhov chaw. Tshawb xyuas qhov nyuaj ntawm cov qauv ntawm txhua qhov cua sov, txheeb xyuas qhov ncaj, thiab tiv thaiv qhov chaw thaum lub sij hawm khaws cia thiab thauj: khawb los yog qhov corrosion ntawm lub caij nplooj ntoos hlav yuav ua rau lub neej luv dua li qhov sib txawv me me. Paub meej tias cov ntsiab lus vanadium tau tshaj tawm hauv daim ntawv pov thawj, txij li lub ntsiab lus tseem ceeb rau cov nplej - kho tus cwj pwm ntawm qib thiab nws qhov poob hloov kev ua haujlwm qaug zog.
FAQ
Q: Dab tsi ntawm cov hlau yog ASTM A519 qib 6150?
Nws yog chromium-vanadium alloy steel nrog txog 0.5% carbon, muab los ua seamless mechanical tubing rau caij nplooj ntoos hlav thiab siab - kev siv qaug zog.
Q: Puas yog 6150 magnetic?
Yog lawm. Nws yog ferritic -martensitic steel thiab yog cov hlau nplaum sib nqus hauv txhua qhov cua sov- kho mob.
Q: Qhov txawv ntawm 6150 thiab 5160 chav kawm yog dab tsi?
6150 muaj vanadium thiab muaj ntau dua chromium. Qhov ntawd ua kom zoo dua cov qauv nplej thiab txhim kho kev qaug zog thiab khaws cia ntawm qhov ntsuas kub nruab nrab, thaum cov chav kawm 5160 tseem qis dua - nqi hloov nrog kev ua haujlwm zoo.
Q: Can 6150 tubing yuav welded?
Nws tuaj yeem welded nrog preheat, qis -hydrogen consumables thiab post-weld kev nyuaj siab nyem, tab sis welded pob qij txha nyob rau hauv lub caij nplooj ntoos hlav steel ntawm cov pa roj carbon theem no yog zam nyob rau hauv cov cheeb tsam uas muaj kev ntxhov siab heev vim hais tias tshav kub- thaj tsam cuam tshuam poob qaug zog.
Q: Qhov twg tshav kub- txoj kev kho mob ua rau lub neej qaug zog zoo tshaj?
Austenitizing nrog nruj nplej- loj tswj raws li austempering feem ntau muab qhov zoo tshaj plaws ua ke ntawm hardness thiab toughness, thiab nws kuj txo distortion nyob rau hauv ntev, slender qhov chaw.
Q: Yuav ua li cas lub raj yuav raug txiav txim?
Qhia rau sab nraud txoj kab uas hla, phab ntsa, ntev, chav kawm kam rau ua, lub quenched thiab tempered mob, thiab lub hardness los yog tensile band yuav tsum tau, ua ke nrog rau tej qhov chaw kuaj thiab decarburization txwv.
