Cov nyhuv ntawm galvanized steel yeeb nkab kev ua tau zoo

(1) Cov pa roj carbon; Qhov siab dua cov ntsiab lus carbon, qhov siab dua qhov hardness ntawm cov hlau, tab sis qhov phem nws cov plasticity thiab toughness.
(2) sulfur; Nws yog cov khib nyiab tsis zoo hauv cov hlau, thiab cov hlau uas muaj cov ntsiab lus sulfur yog ib qho yooj yim rau nkig thaum nws ua tiav nyob rau hauv lub siab kub, feem ntau hu ua kub brittleness.
(3) Phosphorus; Yuav ua rau cov yas thiab tawv tawv ntawm cov hlau poob qis, tshwj xeeb tshaj yog nyob rau qhov kub thiab txias, qhov tshwm sim no hu ua txias brittleness. Nyob rau hauv high-zoo hlau, sulfur thiab phosphorus yuav tsum tau nruj me ntsis tswj. Txawm li cas los xij, ntawm qhov tod tes, cov pa roj carbon tsawg muaj cov sulfur thiab phosphorus ntau dua, uas tuaj yeem ua kom yooj yim txiav, thiab nws muaj txiaj ntsig zoo los txhim kho kev ua haujlwm ntawm cov hlau.
(4) Manganese; tuaj yeem txhim kho lub zog ntawm cov hlau, tuaj yeem txo thiab tshem tawm cov kev tsis zoo ntawm leej faj, thiab tuaj yeem txhim kho cov tawv tawv ntawm cov hlau, cov hlau alloy siab nrog cov ntsiab lus siab manganese (siab manganese steel) muaj kev hnav zoo thiab lwm yam khoom siv lub cev.
(5) Silicon; Nws tuaj yeem txhim kho cov tawv tawv ntawm cov hlau, tab sis cov plasticity thiab toughness poob qis, hluav taws xob hlau muaj qee qhov nyiaj ntawm silicon, tuaj yeem txhim kho cov khoom sib nqus mos.
(6) Tungsten; Nws tuaj yeem txhim kho cov xim liab thiab thermal zog ntawm cov hlau, thiab txhim kho qhov hnav tsis kam ntawm cov hlau.
(7) Chromium; Nws tuaj yeem txhim kho lub hardenability thiab hnav tsis kam ntawm steel, thiab txhim kho corrosion kuj thiab oxidation tsis kam ntawm hlau.
(8) Zinc; Txhawm rau txhim kho corrosion kuj, cov yeeb nkab steel dav dav (dub yeeb nkab) yog galvanized. Galvanized steel yeeb nkab yog muab faib ua kub dip galvanized thiab hluav taws xob steel zinc ob, kub dip galvanized galvanized txheej yog tuab, hluav taws xob galvanized qis nqi, yog li muaj galvanized steel yeeb nkab.
