Raws li qhov zoo thiab kev ua tau zoo ntawm cov kav hlau steel, peb tau sau cov khoom ntawm cov khoom sib txawv ntawm cov hlau uas muaj
Cov pa roj carbon:Qhov siab dua cov ntsiab lus carbon ntau dua qhov hardness ntawm cov hlau cuaj tab sis qhov phem dua cov plasticity thiab toughness.
Sulfur:Nws yog ib qho teeb meem impurity nyob rau hauv steel kav.Yog hais tias cov hlau muaj cov ntsiab lus sulfur siab.it yog ib qho yooj yim los ua nkig ntawm qhov kub thiab txias.Uas feem ntau hu ua kub brittleness.
Phosphorus:Nws tuaj yeem txo cov plasticity thiab toughness ntawm steel, tshwj xeeb tshaj yog nyob rau hauv qis kub.Qhov tshwm sim no yog hu ua txias brittleness.In high-quality steel, sulfur thiab phosphorus yuav tsum nruj me ntsis tswj. Ntawm qhov tod tes., cov ntsiab lus siab ntawm sulfur thiab phosphorus. nyob rau hauv tsawg carbon steel yuav ua rau nws yooj yim mus txiav, uas yog conducive rau kev txhim kho cov kev ua tau zoo ntawm cov hlau.
Manganese:nws tuaj yeem txhim kho lub zog ntawm cov hlau, tsis muaj zog thiab tshem tawm cov kev tsis zoo ntawm cov sulfur, thiab txhim kho cov hardenability ntawm steel.
High alloy steel (siab manganese steel) nrog manganese cov ntsiab lus muaj lub cev zoo xws li hnav tsis kam.
Silicon:Nws tuaj yeem txhim kho hardness ntawm steel, tab sis nws cov yas thiab toughness txo.Tab sis silicon tuaj yeem txhim kho cov khoom sib nqus mos.
Tungsten:Nws tuaj yeem txhim kho cov xim liab thiab thermal zog ntawm cov hlau, thiab txhim kho cov hnav tsis kam ntawm cov hlau.
Chromium:Nws tuaj yeem txhim kho lub hardena, hnav tsis kam.corrosion kuj thiab oxidation tsis kam ntawm hlau.
Vanadium:Nws tuaj yeem kho cov qauv ntawm cov hlau thiab txhim kho lub zog, toughness thiab hnav tsis kam ntawm steel.Thaum nws melts rau hauv austenite ntawm qhov kub thiab txias.Lub hardenability ntawm hlau tuaj yeem nce ntxiv.Ntawm qhov tsis sib xws, thaum nws muaj nyob rau hauv daim ntawv ntawm carbide, nws hardenability yuav raug txo.
