GB Qib B GB 712 Chemical element
GB Qib B GB 712 tshuaj muaj pes tsawg leeg muaj qhov tseem ceeb ntawm GB Qib B GB 712 cov khoom siv tshuab. Ntawm tag nrho cov GB Qib B GB 712 hais. Carbon yog hardening keeb. Silicon pab txhawb lub zog. Manganese yog qhov tseem ceeb austenite stabilizing cov ntsiab lus pab txhawb kev tsim cov qauv kev ntxhib los mos thiab ua rau 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.
