GB 17Cr2Ni2Mo GB/T 17107 Tshuaj
Carbon, Silicon, Manganese, Phosphorus, Sulfur yog cov ntsiab lus tseem ceeb hauv GB 17Cr2Ni2Mo GB / T 17107.
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 kom lub zog ruaj khov, 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 pua .
Feem ntau cov sulfur yog ib qho teeb meem, uas ua rau cov kub brittleness ntawm steel siab, thiab cov ntsiab lus ntawm sulfur yog txwv tsis pub tsawg tshaj li 0.05 feem pua.
