JIS G4051 S45C Steel Paub meej
JIS G4051 S45C steel yog cov khoom siv tseem ceeb thiab siv dav hauv kev lag luam thiab kev tsim khoom. Nws yog ib hom carbon steel uas ua raws li cov qauv tsim los ntawm Japanese Industrial Standards (JIS).
Cov hlau no muaj cov ntsiab lus carbon ntawm ib ncig ntawm 0.45%, uas muab nws cov khoom tshwj xeeb thiab lub cev. Nyob rau hauv cov nqe lus ntawm lub zog, nws muaj ib tug kuj siab tensile lub zog, ua rau nws dais tseem ceeb zog yam tsis tau yooj yim rupturing. Nws qhov hardness kuj tsim nyog rau kev saib xyuas, ua rau nws tsim nyog rau cov ntawv thov uas yuav tsum tau hnav thiab puas, xws li hauv kev tsim cov tshuab, cov cuab yeej, thiab cov khoom siv.
Lub machinability ntawm JIS G4051 S45C steel yog qhov zoo. Nws tuaj yeem ua tiav thiab zoo li tus siv ntau yam kev ua haujlwm machining, uas yog qhov zoo tshaj plaws hauv kev tsim khoom. Qhov no ua rau nws yog qhov kev xaiv nrov rau kev tsim ntau yam khoom xws li iav, ncej, thiab bolts.
Hais txog nws cov microstructure, nws feem ntau muaj ferrite thiab pearlite. Lub ferrite muab ib qho kev kawm ntawm ductility, tso cai rau cov hlau deform mus rau ib qho twg yam tsis tau tawg, thaum lub pearlite pab txhawb rau nws tag nrho lub zog thiab hardness.
Kev kho cua sov tuaj yeem siv rau JIS G4051 S45C steel kom zoo dua nws cov khoom. Annealing tuaj yeem txhim kho nws cov ductility thiab txo cov kev ntxhov siab sab hauv, thaum quenching thiab tempering tuaj yeem ua rau nws cov tawv tawv thiab tawv tawv nyob ntawm qhov tshwj xeeb ntawm daim ntawv thov.
Piv rau lwm cov hlau, JIS G4051 S45C muaj qhov sib npaug zoo ntawm lub zog thiab kev ua haujlwm ntawm tus nqi tsim nyog. Txawm li cas los xij, zoo li feem ntau cov pa roj carbon steel, nws yuav raug cuam tshuam rau corrosion hauv qee qhov chaw, thiab kev tiv thaiv tsim nyog yuav tsum tau ua. Zuag qhia tag nrho, JIS G4051 S45C steel yog cov khoom tseem ceeb nrog ntau yam kev siv thiab kev ua tau zoo hauv kev lag luam hauv ntiaj teb.
