GB Standard 5CrMnMo Round Bar
5CrMnMo round bar yog pwm hlau uas yog tsim los ntawm kev ntxiv peb lub ntsiab: Cr, Mn thiab Mo raws li cov pa roj carbon nruab nrab. Nws tseem tuaj yeem suav tias yog hloov Ni lub hauv paus hauv 5CrNiMo steel nrog Mn keeb. Cov hlau no yog cov hlau ua haujlwm kub. Tsuas yog nws cov hardenability thiab thermal qaug zog tsis kam, 5CrMnMo steel muaj cov khoom zoo sib xws rau 5CrNiMo steel, tab sis nws cov hardenability me ntsis zuj zus. Cov hlau no yog tsim rau kev tsim cov ntawv thov uas xav tau lub zog siab dua thiab ua haujlwm siab. Ntau hom abrasive forging tuag. Thaum yuav tsum tau muaj zog dua, electroslag remelted steel yuav siv tau. Cov ntsiab lus carbon hauv 5CrMnMo steel yog khaws cia ntawm 0.40% ~ 0.60%, uas tuaj yeem tau txais lub zog siab dua thiab thermal qaug zog, thiab qee yam Hardness thiab hnav tsis kam, zoo toughness steel thiab thermal conductivity .

5CrMnMo puag ncig Tshuag hlau Khoom duab
Lub hom phiaj tseem ceeb ntawm kev ntxiv Cr, Mn thiab Mo rau 5CrMnMo yog txhawm rau txhim kho cov tawv tawv ntawm cov hlau. Tshwj xeeb tshaj yog thaum lawv ua hauj lwm ua ke, lub hardenability tau zoo heev. Cr, Mn, thiab Mo cov ntsiab lus tuaj yeem yaj hauv ferrite rau cov khoom siv ntxiv dag zog, thiab tuaj yeem yaj hauv Fe3C los ua (Fe, Cr, Mo) 3C kom nws cov tawv tawv thiab txhim kho cov hnav tsis kam ntawm cov hlau. Kev sib xyaw ua ke ntawm Cr, Mn, thiab Mo cov ntsiab lus tseem ceeb txhim kho kev ruaj ntseg ntawm cov hlau. Mo lub caij tuaj yeem txo qhov kub hnyiab thiab ua kom cov nplej zoo dua.
