20Cr alloy seamless steel yeeb nkabyog ib qho ntawm cov yeeb nkab steel hlau nrog cov khoom siv loj tshaj plaws hauv kuv lub teb chaws thiab muaj ntau yam kev siv.Suav GB txheem steel tooj 20Cr;Japanese JIS tus qauv steel tooj SCr22;German DIN txheem steel tooj 20Cr4;British BS tus qauv steel tooj 590M17;Fabkis NF tus qauv steel tooj 18C3;American AISI / SASTM tus qauv steel tooj 5120;International Standards Organization ISO txheem steel No. 20Cr4.
Yam ntxwv
20Cr alloy steel yeeb nkabmuaj kuj zoo hardenability, nruab nrab lub zog thiab toughness.Lub hardenability ntawm roj quenching rau ib nrab martensitic hardness yog Φ20-Φ23mm.Tom qab carburizing thiab quenching nto ntxiv dag zog rau kev kho mob, zoo koob zoo li tempered martensite yuav tau nyob rau saum npoo ntawm pwm nrog ib tug hardness ntawm 58-62HRC;Cov qauv qis-carbon martensite yuav tau txais nyob rau hauv qhov chaw nrog hardness ntawm 35-40HRC.Lub matrix muaj lub zog siab thiab tawv, thiab tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm kev ua haujlwm siab hardness, siab zog, siab toughness thiab tsim nyog corrosion kuj ntawm cov pwm ua haujlwm txias.Normalizing tuaj yeem txhawb cov spheroidization ntawm cov qauv, kho qhov loj proeutectoid ferrite, thiab txhim kho qhov kev ua tau zoo ntawm qhov khoob.
Kev siv
20Cr seamless steel kavfeem ntau yog siv los tsim cov khoom siv carburized (roj quenching) nrog cov tub ntxhais muaj zog siab, hnav saum npoo, hla ntu hauv qab 30mm, los yog cov duab nyuaj thiab cov khoom siv qis, xws li: tshuab cuab yeej gearbox iav, iav shafts, Cams, worms, piston pins , claw clutches, thiab lwm yam.;rau qhov chaw nrog kev kho cua sov me me deformation thiab hnav tsis kam, high-frequency nto quenching yuav tsum tau ua tom qab carburization, xws li lub zog, shafts.20Cr seamless kavkuj tuaj yeem siv rau hauv lub xeev quenched thiab tempered los tsim cov khoom uas ua haujlwm ntawm kev kub ceev thiab tiv taus qhov cuam tshuam nruab nrab.Nws kuj tseem tuaj yeem siv los ua cov pa roj carbon tsawg martensitic quenching steel kom ntxiv dag zog thiab tensile lub zog ntawm cov hlau.
