GB Qib A36 GB 712 Taw Qhia
GB Qib A36 GB 712 yog siv rau ntau yam kev siv, xws li kev tsim choj, kev siv tshuab, kev tsim nkoj, thiab cov khoom siv tsheb. Nws yog feem ntau siv nyob rau hauv qhov tob ntawm cov choj thiab lwm cov qauv loj, raws li nws tuaj yeem ua rau muaj kev ntxhov siab ntau dua. Nws kuj yog siv nyob rau hauv tsheb rau ncua kev kawm ntawv qhov chaw thiab lwm yam Cheebtsam, xws li tsav shafts thiab axles. Hauv kev tsim cov nkoj, nws yog siv rau lub nkoj thav duab thiab lwm qhov chaw, vim nws lub zog thiab kev tiv thaiv corrosion. Nws tseem tuaj yeem siv rau hauv cov tshuab ua lag luam, xws li xovxwm thiab conveyor rollers, vim nws tsis kam hnav thiab tsim kua muag.

GB Qib A36 GB 712 Chemical Element
GB Qib A36 GB 712 tshuaj muaj pes tsawg leeg muaj qhov tseem ceeb ntawm GB Qib A36 GB 712 cov khoom siv tshuab. Ntawm tag nrho cov GB Qib A36 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.
