Cov yam ntxwv tseem ceeb thiab kev siv ntawm 1.4002 / 405
Txhim kho Weldability:Kev sib xyaw ua ke ntawm cov pa roj carbon tsawg thiab txhuas ntxiv ua rau txhim kho weldability piv rau lwm cov qib ferritic, txo qhov nyiam ntawm cov qoob loo loj hlob thiab tawv tawv hauv tshav kub- cuam tshuam cheeb tsam.
Zoo Siab -Tub kub Oxidation Resistance:Muab kev tiv thaiv txaus rau scaling thiab oxidation ntawm qhov kub siab txog li 650 degree, haum rau nruab nrab -kev siv kub.
Tsawg Ua Haujlwm Hardening Rate:Tsom pom kev ua haujlwm qis dua li qib austenitic, uas tuaj yeem ua tau zoo rau qee yam kev ua haujlwm.
Sib nqus thiab nqi-zoo:Muaj zog sib nqus thiab txuag nyiaj ntau dua npib tsib xee- muaj cov qib austenitic.
Cov ntawv thov tseem ceeb:
Thaum tshav kub kub Exchangers:Cheebtsam hauv nruab nrab- cov khoom siv hluav taws xob hloov pauv kub.
Cov khoom siv Petrochemical:Cov tais diav, hauv ob sab phlu, thiab sab hauv hauv kab thiab cov hlab ntsha.
Cov khoom siv Annealing:Rauv qhov chaw, pob tawb, thiab cov khoom siv ua haujlwm ntawm qhov kub nruab nrab.
Chav Nozzles:Cheebtsam hauv chav tshuab.
Automotive:Cov pa hluav taws xob cov khoom hauv qis dua - qhov kub thiab txias.
Architectural:Kho kom zoo nkauj daim ntaub ntawv qhov twg weldability yuav tsum tau.
405 (1.4002) piv rau 410 (1.4006) thiab 304 (1.4301) li cas?
405 txawv ntawm 410 feem ntau nyob rau hauv nws cov ntsiab lus qis carbon thiab txhuas ntxiv, uas muab kev txhim kho weldability thiab txo hardening thaum vuam. Thaum 410 tuaj yeem ua rau muaj zog heev nyob rau hauv tshav kub- thaj tsam cuam tshuam thaum lub sij hawm vuam, 405 tseem softer thiab ntau ductile, ua rau nws nyiam rau welded Cheebtsam. Piv rau 304, 405 muaj kev tiv thaiv corrosion tsawg, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig chloride, tab sis tsis tshua muaj nqi thiab nqi ntau dua - ruaj khov. Nws yog hlau nplaum, thaum 304 tsis yog -sib nqus{13}} feem ntau yog xaiv rau nruab nrab- cov ntawv thov kub qhov chaw weldability tseem ceeb thiab cov kev xav tau corrosion tsis hnyav.
Dab tsi yog qhov kev txiav txim siab vuam rau 405?
405 muaj qhov zoo weldability ntau dua li lwm cov qib ferritic vim nws cov ntsiab lus tsis tshua muaj carbon thiab txhuas ntxiv. Cov ntsiab lus tseem ceeb suav nrog:
Tsawg cua sov input vuam cov tswv yim pom zoo kom txo qis kev loj hlob ntawm cov nplej
Preheating (150-200 degree) tej zaum yuav muaj txiaj ntsig zoo rau cov ntu tuab
Muab cov hlau sib txuam (405 hom) lossis austenitic fillers (309L) tuaj yeem siv
Tom qab-weld kev kho cua sov ntawm 760-790℃tom qab txias qeeb tuaj yeem txhim kho ductility
Vuam tuaj yeem ua tau yam tsis muaj qhov tseem ceeb hauv cov cua sov- thaj tsam cuam tshuam
Resistance vuam yog haum rau nyias gauge daim ntaub ntawv
Qhov ntsuas kub li cas yog 405 haum rau?
405 yog tsim rau kev pabcuam txog li 650℃(1200℃F) rau kev ua haujlwm tas mus li. Nws tuav tau zoo oxidation tsis kam nyob rau hauv no ntau yam, ua rau nws haum rau nruab nrab -kub daim ntaub ntawv xws li tshav kub exchanger Cheebtsam thiab lub qhov cub. Rau cov ntawv thov uas yuav tsum tau muaj peev xwm kub siab dua, qib nrog cov ntsiab lus chromium siab dua xws li 446 (1.4762) lossis qib austenitic xws li 309/310 yuav tsim nyog dua. Ntawm qhov kub siab, 405 tuav lub zog zoo thiab tiv thaiv qhov ntsuas, tab sis ntev ntev ntawm qhov kub siab tshaj 650℃tuaj yeem ua kom oxidation.
