GB Qib E32 GB 712 Chemical Element
Carbon, Silicon, Manganese, Phosphorus, Sulfur yog cov ntsiab lus tseem ceeb hauv GB Qib E32 GB 712.
Cov pa roj carbon monoxide yog qhov tseem ceeb tshaj plaws hardening nyob rau hauv steel.
Silicon pab txhawb lub zog. Zoo li manganese, silicon yog siv los tswj lub zog ntawm cov hlau thaum lub sij hawm tsim cov hlau.
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 yog ib qho teeb meem. Txo cov plasticity thiab toughness ntawm steel thiab tshwm txias brittleness. Nws tuaj yeem txhim kho lub zog ntawm cov hlau, thiab txhim kho cov atmospheric corrosion stability. Cov ntsiab lus yuav tsum txwv tsawg dua 0.05%.
Feem ntau cov sulfur yog ib qho teeb meem, uas ua rau kub brittleness ntawm steel siab, thiab cov ntsiab lus ntawm sulfur yog txwv tsis pub tsawg tshaj li 0.05%.
