SMn438 cov qauv thiab cov khoom siv tshuaj muaj pes tsawg leeg
Jul 11, 2023
SMn438 yog ib hom hlau alloy nrog cov qauv tshwj xeeb, cov khoom zoo tshaj plaws, thiab cov tshuaj muaj pes tsawg leeg.
Cov qauv:
SMn438 yog tsim nyob rau hauv raws li cov qauv kev lag luam los xyuas kom meej qhov zoo thiab kev ua tau zoo. Cov qauv no qhia cov kev txwv xws li cov tshuaj lom neeg muaj pes tsawg leeg, cov khoom siv kho tshuab, thiab qhov ntev ntev. Kev ua raws li cov qauv no yog qhov tseem ceeb rau nws siv hauv ntau yam kev siv.
Cov khoom:
Qhov no alloy steel exhibits zoo heev mechanical zog. Nws muaj lub zog tensile siab, ua rau nws tiv taus qhov hnyav thiab kev ntxhov siab. Lub zog tawm los ntawm SMn438 kuj tseem ceeb, kom ntseeg tau tias nws tsis deform yooj yim nyob rau hauv siab. Tsis tas li ntawd, nws muaj qhov zoo hardness thiab hnav tsis kam, ua rau nws haum rau qhov chaw uas raug kev sib txhuam thiab kev cuam tshuam. SMn438 kuj muaj qhov zoo ductility thiab toughness, tso cai rau nws los tsim thiab ua tiav rau hauv cov duab sib txawv yam tsis muaj cracking.
Tshuaj muaj pes tsawg leeg:
Cov tshuaj muaj pes tsawg leeg ntawm SMn438 yog ua tib zoo tsim kom ua tiav nws cov khoom tsim nyog. Nws feem ntau muaj cov ntsiab lus xws li carbon (C), manganese (Mn), silicon (Si), thiab lwm yam alloying ntsiab. Cov ntsiab lus carbon muab hardness thiab lub zog, thaum manganese pab txhawb toughness thiab hardenability. Silicon txhim kho cov hlau lub zog thiab kub tsis kam. Cov kev faib ua feem ntawm cov ntsiab lus no yog tswj xyuas kom cov hlau ua tau raws li qhov xav tau ntawm kev ua tau zoo.
Hauv kev xaus, SMn438 yog ib qho tseem ceeb alloy steel nrog cov qauv kev cai, cov khoom zoo, thiab cov tshuaj muaj pes tsawg leeg. Nws ua ke ntawm lub zog, hardness, hnav tsis kam, thiab ductility ua rau nws haum rau ntau yam kev siv hauv kev lag luam xws li tshuab tsim, tsheb, thiab engineering. Txawm hais tias nws yog rau lub zog, ncej, lossis lwm yam tseem ceeb, SMn438 muaj kev ua tau zoo thiab ua haujlwm ntev.
