Tungsten txhim khu cov xim liab hardness, kub lub zog, thiab hnav tsis kam ntawm kauv steel kav.
Silicon txhim kho lub hardness ntawm kauv steel kav tab sis txo lawv cov yas thiab toughness. Ib qho nyiaj ntawm silicon hauv kauv steel kav siv hauv hluav taws xob engineering tuaj yeem txhim kho cov khoom sib nqus zoo.
Chromium tsub kom lub hardenability thiab hnav tsis kam ntawm kauv steel kav, nrog rau txhim kho lawv corrosion kuj thiab oxidation kuj. Txhawm rau txhim kho cov kev tiv thaiv corrosion ntawm cov kav dej los tiv thaiv corrosion (dub kav), galvanization yog ua.
Sulfur yog ib qho teeb meem impurity nyob rau hauv kauv steel kav. Cov ntsiab lus sulfur siab dua ua rau cov kav dej ua rau embrittlement thaum lub sijhawm ua haujlwm kub, feem ntau hu ua kub luv.
Cov ntsiab lus carbon ncaj qha cuam tshuam nrog lub hardness ntawm steel; Qhov siab dua cov ntsiab lus carbon, qhov nyuaj dua cov hlau, tab sis nrog txo cov plasticity thiab toughness.
Manganese txhim khu lub zog ntawm kauv steel kav, txo cov kev tsis zoo ntawm leej faj, thiab txhim kho lawv cov hardenability. High-alloy kauv steel kav nrog siab manganese cov ntsiab lus (high-manganese kauv steel kav) pom zoo hnav tsis kam thiab lwm yam khoom siv lub cev.
Phosphorus ho txo cov plasticity thiab toughness ntawm kauv steel kav, tshwj xeeb tshaj yog nyob rau hauv qis kub. Qhov no tshwm sim yog hu ua txias shortness. Nyob rau hauv high-zoo kauv steel kav, sulfur thiab phosphorus cov ntsiab lus yuav tsum tau nruj me ntsis tswj. Txawm li cas los xij, los ntawm lwm qhov kev xav, cov ntsiab lus ntawm cov sulfur thiab phosphorus ntau dua hauv cov kav hlau uas muaj cov pa roj carbon tsawg tuaj yeem ua kom yooj yim chipping, uas muaj txiaj ntsig zoo rau kev txhim kho cov khoom siv ntawm cov kav hlau kav.
