GB DT4 GB / T 6983 Cov khoom siv tshuaj
GB DT4 GB / T 6983 tshuaj muaj pes tsawg leeg muaj qhov tseem ceeb ntawm GB DT4 GB / T 6983 cov khoom siv tshuab. Ntawm tag nrho cov GB DT4 GB / T 6983 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.

GB DT4 GB / T 6983 Lub cev muaj zog
Lub cev muaj zog ntawm GB DT4 GB / T 6983 suav nrog lub zog siab, qhov hnyav, ua haujlwm ntev, ductility thiab tsis kam tiv thaiv corrosion. Hlau, raws li peb txhua tus paub, muaj lub zog zoo txawm tias nws yog qhov hnyav. Qhov tseeb, qhov piv ntawm lub zog rau qhov hnyav rau steel yog qhov qis tshaj li lwm yam khoom siv hauv tsev muaj rau peb.
