40Cr alloy steel phaj yog siv dav hauv nruab nrab - carbon alloy structural steel, muaj npe nrov rau nws cov khoom siv zoo heev thiab kev ua haujlwm. Nws plays lub luag haujlwm tseem ceeb hauv kev tsim khoom, kev lag luam tsheb, khoom siv engineering, thiab lwm yam. Nov yog cov lus qhia ntxaws ntxaws los ntawm cov yam ntxwv ntawm cov khoom siv, cov xwm txheej ntawm daim ntawv thov, qhov zoo tshaj plaws, thiab ua cov ntsiab lus tseem ceeb:

 

Mechanical Properties

Tom qab quenching thiab tempering kev kho mob, 40Cr exhibits zoo heev mechanical zog:

 

Tensile zog: Ntau dua los yog sib npaug rau 980MPa

Yield zog: Ntau dua los yog sib npaug rau 785MPa

Elongation: Ntau dua lossis sib npaug li 9%

Lub zog cuam tshuam (Akv): Ntau dua lossis sib npaug rau 47J
Nws muaj qhov sib npaug zoo ntawm lub zog thiab tawv, ua rau nws muaj peev xwm tiv taus ob qho tib si zoo li qub thiab qee qhov dynamic loads.

Kev ua tau zoo

Hardenability: Nws muaj zoo hardenability. Rau workpieces nrog tus ntoo khaub lig-sectional txoj kab uas hla los yog thickness tsawg tshaj li 50 hli, uniform hardening yuav ua tau tiav los ntawm cov roj txias, kom ntseeg tau zoo ib yam ntawm cov workpiece.

Weldability: Weldability yog nruab nrab. Preheating (feem ntau 150-250 degree) yuav tsum tau ua ntej vuam kom txo tau qhov kev pheej hmoo ntawm qhov txias txias, thiab tom qab vuam cua sov yog pom zoo kom tshem tawm cov welding residual stress.

Machineability: Nyob rau hauv lub xeev annealed, nws muaj zoo machinability, uas yog haum rau ua ntau yam complex qhov chaw; Tom qab quenching thiab tempering, nws hardness nce, thiab xaiv cov cuab yeej txiav tsim nyog thiab tsis yog yuav tsum tau rau machining.

 

 

 

 

 

 

 

 

Cov ntawv thov ib txwm nyob hauv cov teb ntsig txog

Ua tsaug rau nws cov khoom zoo heev, 40Cr alloy steel phaj yog dav siv nyob rau hauv ntau yam teb:

 

Mechanical Manufacturing: Siv los tsim cov khoom tseem ceeb xws li shafts, gears, bolts, thiab txuas rods uas dais nruab nrab loads thiab muaj qee yam hnav tsis kam. Piv txwv li, lub ntsiab ncej ntawm lub tshuab cuab yeej, lub iav gearbox ntawm kev tsim kho tshuab, thiab lwm yam.

Automotive Kev Lag Luam: Siv rau cov khoom tseem ceeb xws li tsheb kis tau tus mob shafts, crankshafts, thiab ib nrab shafts, uas muaj peev xwm tiv taus lub alternating loads thiab torque thaum lub tsheb khiav.
