Galvanized steel yeeb nkabtau ua ntau hom yeeb nkab steel hauv kev lag luam steel yeeb nkab tam sim no. Ua ntej tshaj plaws, peb yuav tsum hais txog ib qho tseem ceeb ntawm cov yeeb nkab steel: "carbon". Tsis tas li ntawd, cov ntsiab lus carbon, rau qee qhov, txiav txim siab qhov nyuaj ntawm cov yeeb nkab steel tiav. Qhov ntau cov yeeb nkab steel tiav muaj cov pa roj carbon, nws nyuaj dua. Raws li qhov tshwm sim, nws yuav ua kom muaj kev ruaj ntseg ntau dua kom ntev lub neej kev pab cuam ntawm cov yeeb nkab steel. Txawm li cas los xij, nws tsis tuaj yeem tsis lees paub tias cov ntsiab lus carbon ntau dua yuav cuam tshuam rau lub zog tensile ntawm cov yeeb nkab steel. Yog li ntawd, nws tseem tsim nyog rausteel yeeb manufacturerscoj lub ntsiab lus mus rau hauv tus account nyob rau hauv qhov tseeb ntau lawm processing.
Niaj hnub no, nrog kev txhim kho txuas ntxiv ntawm cov txheej txheem ua tiav thiab kev nce qib tag nrho ntawm tib neeg, muaj kev sib txawv ntawm cov kav dej hauv kev xav tau zoo. Feem ntau, galvanized steel yeeb nkab tau txais kev nyiam ntau dua los ntawm cov neeg siv khoom feem ntau ntawm ntau hom kav dej, vim nws cov khoom ruaj khov zoo dua qub. Nrog siv rausteel yeeb nkab nqi, yuav ua li cas kom cov yeeb nkab rational pricing muaj ntau yam ua rau cov khoom siv ntawm cov yeeb nkab steel. Yog li, nws tau dhau los ua ntau thiab tsim nyog rau cov neeg siv kawg kom muaj kev paub txaus ua ntej ntawm ntau hom kav dej ntawm lawv qhov kev yuav khoom ntawm cov kav dej uas xav tau rau lub hom phiaj kawg.
Ntawm qhov tod tes, los ntawm cov txheej txheem tsim khoom, cov khoom siv ntawm cov yeeb nkab steel me ntsis muaj kev cuam tshuam zoo rau kev ua haujlwm ntawm cov yeeb nkab steel hauv lub hom phiaj tiag tiag. Hais txogtxias dov steel yeeb nkab qhov ntau thiab tsawg, muaj ntau hom steel kav rau cov neeg siv khoom xaiv. Ntawm no, peb xav hais txog lwm qhov tseem ceeb ntawm cov khoom "sulfur". Tsis tas li ntawd, cov ntsiab lus ntawm leej faj kuj tuaj yeem ua rau qee yam cuam tshuam rau qhov zoo ntawm cov yeeb nkab steel. Raws li cov neeg sab hauv hauv kev lag luam steel paub, sulfur yog suav tias yog ib yam khoom muaj teeb meem. Yog tias cov ntsiab lus ntawm sulfur siab dhau lawm, yuav muaj qee yam cuam tshuam rau cov yeeb nkab steel zoo thiab txawm tias ua rau qhov kawg ntawm cov kav dej. Tsis tas li ntawd, nrog rau kev siv lub zog tensile ntawm cov yeeb nkab steel, cov tuam ntxhab yuav tsum tau them nyiaj ntau rau "phosphor" cov ntsiab lus hauv cov yeeb nkab tiav. Raws li txoj cai, cov ntsiab lus "phosphor" siab dhau lawm yuav ua rau qis zog tensile ntawm cov yeeb nkab steel. Yog li ntawd, nws zoo nkaus li tseem ceeb heev rau cov tuam txhab steel yeeb nkab yuav tsum tau them nyiaj ntau rau cov ntsiab lus ntawm cov yeeb nkab steel hauv kev tsim khoom tiag tiag.
