434 stainless hlau ua tau zoo nyob rau hauv cov nqe lus ntawm machinability thiab yuav siv tau nrog tag nrho cov txheej txheem machining txheej txheem.
Nws muaj kev ua tau zoo txiav thiab tuaj yeem ua cov haujlwm ua haujlwm xws li txiav, drilling, milling, thiab tig. Tsis tas li ntawd, nws cov weldability kuj zoo heev thiab tuaj yeem siv rau kev ua haujlwm welding. Tau kawg, zoo li lwm yam khoom siv, ua ntej machining, nws tseem yuav tsum tau xaiv cov cuab yeej tsim nyog, cov khoom siv thiab cov txheej txheem ua haujlwm raws li qhov xwm txheej tshwj xeeb kom ntseeg tau tias qhov ua tau zoo tshaj plaws.
Kev tsim ntawm 434 stainless hlau:
434 stainless hlau muaj zoo formability thiab yog haum rau ntau yam blanking, shearing thiab kos duab ua hauj lwm. Vim nws cov ductility siab, nws tuaj yeem ua tiav cov duab zoo nyob rau hauv kev ntxhov siab yam tsis muaj deformation ntau dhau los yog tawg. Qhov no ua rau 434 stainless hlau dav siv nyob rau hauv kev tsim cov hlau qhov chaw, ntim, kav dej thiab lwm yam khoom uas muaj cov zoo li xav tau.
Cov txheej txheem tsim nyog thiab cov khoom siv kuj tseem ceeb heev thaum ua haujlwm molding los xyuas kom meej cov khoom zoo molded
434 stainless hlau
Vuam ntawm 434 stainless hlau:
434 stainless hlau tuaj yeem koom nrog siv cov txheej txheem vuam. Cov txheej txheem muaj xws li arc vuam, argon arc vuam, thiab ntshav arc vuam. Ua ntej pib nrog kev sib txuas, xyuas kom cov chaw yuav tsum tau koom nrog yog huv si thiab tsis muaj impurities thiab oxides.
Tom qab vuam tiav lawm, nws raug nquahu kom ntxuav cov vuam kom huv si kom tshem tawm cov oxides thiab lwm yam kab mob uas tsim los ntawm vuam, uas yuav pab txhim kho corrosion kuj ntawm 434 stainless hlau. Cov khoom siv vuam tsim nyog thiab cov txheej txheem yuav tsum raug xaiv kom ntseeg tau tias vuam zoo thiab lub zog.
Annealing ntawm 434 stainless hlau:
Thaum 434 stainless hlau yog soaked thiab annealed, qhov zoo tshaj plaws kub ntau yam yog 788 degree rau 872 degree (1450 degree F txog 1600 degree F). Lub hom phiaj ntawm soaking annealing yog txhawm rau tshem tawm kev ntxhov siab hauv cov khoom thiab txhim kho qhov sib xws ntawm cov nplej.
Cov txheej txheem no tuaj yeem ua tiav los ntawm cua sov 434 stainless hlau mus rau qhov kub thiab txias thiab tswj nws rau qee lub sijhawm.
Tom qab soaking annealing, 434 stainless hlau yuav tsum tau txias hauv huab cua. Lub ntuj txias no pab kom ruaj khov ntawm cov khoom siv, muab nws cov khoom siv zoo dua qub thiab tiv thaiv corrosion.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias qhov kub thiab lub sij hawm tswj tau thaum lub sij hawm annealing txheej txheem kom ntseeg tau tias cov khoom xav tau thiab cov qauv ua tiav. Nyob rau tib lub sijhawm, annealed 434 stainless hlau kuj tseem yuav tsum tau ua ntxiv lossis kho kom tau raws li cov cai tshwj xeeb thiab kev siv.
Hardening ntawm 434 stainless hlau:
434 stainless hlau feem ntau tsis dhau qhov kev hloov pauv tseem ceeb lossis cov tshuaj tiv thaiv tawv thaum kho cua sov. Nyob rau hauv sib piv, ntau ntawm lub zog thiab hardness ntawm 434 stainless hlau yog tiav los ntawm kev ua hauj lwm txias los yog txias deformation. Los ntawm kev ua haujlwm txias, xws li txias dov, kos duab txias lossis kos duab txias, cov qauv nplej ntawm 434 stainless hlau yog deformed, ua rau cov hardness thiab lub zog ntawm cov khoom. Cov txheej txheem deformation txias no qhia txog kev tsis sib haum xeeb thiab cov ciam teb, txwv tsis pub muaj peev xwm ntawm cov nplej kom plam thiab txav mus los.
