GB Q245R GB 713 Chemical Element
GB Q245R GB 713 tshuaj muaj pes tsawg leeg muaj qhov tseem ceeb ntawm GB Q245R GB 713 cov khoom siv tshuab. Ntawm tag nrho cov GB Q245R GB 713 hais. Carbon yog hardening keeb. Silicon pab txhawb lub zog. Manganese yog qhov tseem ceeb ntawm austenite stabilizing cov ntsiab lus pab txhawb kev tsim cov qauv kev ntxhib los mos thiab ua kom muaj zog, lub zog thiab hnav tsis kam. Phosphorus txo cov plasticity thiab toughness thiab tshwm txias brittleness. Lub caij no, Nws tuaj yeem ua kom muaj zog ntawm cov hlau, thiab txhim kho atmospheric corrosion stability. Sulfur ua rau kub brittleness ntawm steel siab.
