41CrMo4 (1.7223) alloy structural steel muaj siab yield zog thiab tensile zog thiab yog haum rau daim ntaub ntawv uas yuav tsum tau muaj zog. 41CrMo4 muaj qhov zoo toughness thiab cuam tshuam tsis kam, thiab tuaj yeem tuav lub zog zoo thiab deformation muaj peev xwm nyob rau hauv siab loads thiab cuam tshuam. 41CrMo4 muaj qhov hnav tsis zoo thiab tshwj xeeb tshaj yog haum rau cov khoom thiab kev ua haujlwm uas yuav tsum tau tiv thaiv hnav. 41CrMo4 muaj qhov zoo weldability thiab yog haum rau cov pa vuam txoj kev.
siv:
Mechanical qhov chaw tsim khoom: 41CrMo4 feem ntau yog siv los tsim cov khoom siv kho tshuab uas xav tau lub zog siab thiab hnav tsis kam, xws li cov kabmob log, lub zog, kis tau tus mob, spur zog, thiab lwm yam.
Kev lag luam tsheb: 41CrMo4 yog siv rau hauv kev tsim cov khoom siv tsheb, xws li cav crankshafts, kis tau tus mob zog, txuas rods, thiab lwm yam.
Kev lag luam forging: 41CrMo4 tuaj yeem siv rau hauv kev tsim cov cuab yeej forging xws li kub tuag, forging tuag, thiab txias extrusion tuag.
Kev lag luam hluav taws xob: 41CrMo4 yog siv rau hauv qhov kub thiab txias cov cuab yeej siv hauv kev lag luam roj av, roj av thiab tshuaj lom neeg kev lag luam, xws li roj drilling kav, li qub thiab petrochemical reactors.
Cov kev kho cua sov feem ntau rau 41CrMo4 suav nrog normalizing, quenching thiab tempering.
Normalizing: Thaum tshav kub kub 41CrMo4 rau qhov tsim nyog kub (feem ntau ntawm 850 degree thiab 880 degree), tuav rau ib lub sij hawm, thiab ces txias nyob rau hauv cov huab cua. Normalizing nce hardness thiab lub zog ntawm steel.
Quenching: Cua sov 41CrMo4 mus rau qhov tsim nyog kub (feem ntau ntawm 830 degree thiab 860 degree ) thiab tom qab ntawd txias nws sai sai tuaj yeem ua tiav lub zog siab thiab tawv, tab sis yuav ua rau muaj kev tawg ntau dua.
Tempering: Thaum tshav kub kub quenched 41CrMo4 mus rau qhov tsim nyog kub (feem ntau ntawm 200 degree thiab 300 degree), tuav nws rau ib lub sij hawm ntawm lub sij hawm thiab ces txias nws ntawm tus nqi tsim nyog. Tempering tuaj yeem txo cov kev ntxhov siab sab hauv ntawm cov hlau thiab txhim kho nws qhov toughness thiab cuam tshuam tsis kam.
