Ob lub alloys pom zoo txhua yam khoom, nrog rau lub zog tensile, yield zog, thiab elongation. Txawm li cas los xij, muaj molybdenum nyob rau hauv 316 stainless hlau me ntsis txo nws cov ductility thaum piv rau 304 stainless hlau. Qhov no txhais tau hais tias 316 stainless hlau yuav tsis tshua muaj kev hloov pauv thaum muaj kev ntxhov siab, txawm hais tias qhov sib txawv feem ntau yog tsawg thiab tsis tshua muaj qhov txwv tsis pub siv hauv kev siv. Ob leeg 304 thiab 316 stainless hlau yog cov weldable heev thiab tuaj yeem tsim siv ntau yam txuj ci xws li vuam, khoov, thiab machining. Lawv cov qauv austenitic ua rau lawv tuaj yeem ua haujlwm rau ntau hom duab thiab ntau thiab tsawg yam tsis tau poob lawv cov kev tiv thaiv corrosion. Txawm li cas los xij, 316 stainless hlau tuaj yeem nyuaj rau vuam vim qhov thermal conductivity ntau dua thiab qis dua thermal expansion coefficient ntawm cov hlau, uas tuaj yeem cuam tshuam qhov zoo ntawm vuam thiab yuav tsum tau ceev faj tswj cov vuam tsis.
304 Stainless hlau puas tuaj yeem welded?
Cov txheej txheem vuam feem ntau siv rau 304 stainless hlau suav nrog TIG (tungsten inert gas) vuam, MIG (hlau inert gas) vuam, thiab qee zaus lo vuam (SMAW). TIG vuam yog qhov zoo dua rau nws txoj kev huv thiab muaj peev xwm tsim cov vuam zoo, tshwj xeeb tshaj yog nyob rau hauv cov ntu nyias. MIG vuam yog nrawm dua thiab kev lag luam ntau dua, ua rau nws tsim nyog rau cov ntu tuab uas qhov kev nrawm yog qhov tseem ceeb. Cov hlua vuam tsis tshua nyiam vim nws muaj kev cuam tshuam ntau dua rau kev sib kis tab sis tuaj yeem siv tau thaum lwm txoj hauv kev tsis ua tau. Kev npaj sib koom ua ke yog qhov tseem ceeb rau kev ua tiav ntawm 304 stainless hlau. Nto yuav tsum tau ntxuav kom huv si thiab tsis muaj roj, roj, nplai, thiab lwm yam kab mob. Sib tsoo nrog cov txhuam hlau tsis muaj hlau lossis cov tshuaj ntxuav tsis muaj tshuaj chloride yuav tsim nyog ua ntej vuam pib. Xaiv cov khoom siv hlau uas tsim nyog yog qhov tseem ceeb. Rau TIG welding, 308L lossis 308LSi rods thiab cov xov hlau feem ntau yog siv vim lawv nyob ze rau 304 stainless hlau, muab kev tiv thaiv corrosion zoo nyob rau hauv ob qho tib si vuam hlau thiab tshav kub-tshuaj lom. Rau MIG vuam, ER308L kuj yog ib qho kev xaiv. Nws yog ib qho tseem ceeb kom phim tus muab tub lim hlau muaj pes tsawg leeg rau lub hauv paus hlau kom ntseeg tau tias muaj kev sib haum xeeb thiab txo qis qhov muaj peev xwm corrosion. Rau TIG thiab MIG welding, siv cov roj tiv thaiv tsis zoo xws li argon tau pom zoo. Ntxiv ib qho me me ntawm helium rau cov roj sib xyaw tiv thaiv tuaj yeem txhim kho arc kev ua tau zoo thiab nkag mus. Rau MIG vuam nyob rau hauv qhov chaw qias neeg lossis cua daj cua dub, kev sib xyaw ntawm argon thiab CO2 yuav siv tau rau kev ruaj ntseg zoo dua ntawm arc thiab kev tiv thaiv ntawm lub pas dej ua ke. Kev siv hluav taws xob ntau dhau thaum lub vuam tuaj yeem ua rau muaj teeb meem xws li poob ntawm corrosion kuj, muaj kev pheej hmoo ntawm distortion thiab warping, thiab nce nyob rau hauv hardness ntawm HAZ, ua rau nws raug kev nyuaj siab corrosion cracking. Yog li ntawd, nws yog ib qho tseem ceeb kom tswj tau lub arc ruaj khov, siv qhov tseeb electrode txoj kab uas hla, thiab kho qhov ceev mus los raws li kev tswj cov cua sov.
