Round Stainless hlau yeeb nkab SS304

Thaum tsim cov kav hlau stainless ua los ntawm SS304, ntau qhov txheej txheem tseem ceeb yuav tsum raug txiav txim siab los xyuas kom meej cov khoom ua tau zoo. Nov yog qee yam tseem ceeb uas yuav tsum nco ntsoov:

Chemical Composition: Qhov sib npaug ntawm cov ntsiab lus alloying yog qhov tseem ceeb. SS304 feem ntau muaj 18-20% chromium thiab 8-10.5% npib tsib xee, uas muab kev tiv thaiv corrosion zoo 1.

Annealing: Yuav kom ua tiav cov khoom siv kho tshuab thiab cov khoom siv zoo, SS304 cov kav dej yuav xav tau kev sib tsoo ntawm qhov kub ntawm 1010-1120 degree, ua raws li qhov txias txias. Cov txheej txheem no yuav pab txo qis kev ntxhov siab sab hauv thiab rov ua kom zoo ib yam microstructure 4.

Kev Ua Haujlwm Txias: Kev ua haujlwm txias tuaj yeem txhim kho lub zog ntawm SS304 tab sis tuaj yeem txo nws cov ductility. Cov txheej txheem xws li kev kos duab, khoov, lossis dov tuaj yeem siv los ua cov kav dej, tab sis kev saib xyuas yuav tsum tau ua kom tsis txhob qhia txog kev ua haujlwm txias heev, uas tuaj yeem tsim nyog rau cov txheej txheem annealing tom ntej 4.

Vuam: SS304 muaj qhov zoo tshaj plaws weldability yam tsis tas yuav tsum tau ua tom qab vuam annealing rau nyias seem. Txawm li cas los xij, qhov hnyav welded yuav xav tau tom qab vuam annealing kom ua kom muaj kev tiv thaiv corrosion. Nws yog ib qho tseem ceeb uas yuav tsum tau siv cov ntaub ntawv tsim nyog xws li E308 lossis E309 kom muaj kev tiv thaiv corrosion 4.

Kev kho cua sov: Txawm hais tias SS304 tsis tuaj yeem ua kom tawv nqaij los ntawm kev kho cua sov vim nws cov qauv austenitic, nws tuaj yeem kho tau (annealed) los txhim kho formability thiab ductility. Nws yog ib qho tseem ceeb kom tsis txhob muaj qhov kub thiab txias ntawm 425-860 degree, qhov twg rhiab heev tuaj yeem tshwm sim, ua rau txo qis corrosion 6.

Machining: SS304 tuaj yeem ua tshuab siv cov qauv kev coj ua. Txawm li cas los xij, rau kev txhim kho machinability, "Ugima" txhim kho versions ntawm SS304 muaj, tshwj xeeb tshaj yog rau bar khoom 6.

Corrosion Resistance: SS304 yog resistant rau ntau yam atmospheric ib puag ncig thiab ntau corrosive xov xwm. Txawm li cas los xij, nws muaj kev cuam tshuam rau pitting thiab crevice corrosion nyob rau hauv sov chloride ib puag ncig. Yog li ntawd, nws yog ib qho tseem ceeb rau kev ntsuam xyuas qhov chaw pabcuam thiab xaiv cov khoom tsim nyog thiab kev kho mob raws li 6.

Kev Tswjhwm Zoo: Thoob plaws hauv cov txheej txheem tsim khoom, txhua kauj ruam los ntawm kev xaiv cov khoom siv raw mus rau qhov kawg ntawm kev tsim khoom yuav tsum tau soj ntsuam nruj me ntsis thiab tswj xyuas kom zoo thiab ua haujlwm ntawm cov kav dej SS304. Qhov no suav nrog cov kev sim uas tsis muaj kev puas tsuaj xws li kev kuaj xyuas qhov tsis zoo ntawm ultrasonic thiab eddy tam sim no kuaj 7.

Los ntawm kev ua tib zoo saib xyuas cov kev txwv no, cov tuam ntxhab tuaj yeem ua kom ntseeg tau tias SS304 round stainless hlau kav ua tau raws li qhov xav tau tshwj xeeb rau lawv cov ntawv thov.
