42CrMo yog cov hlau muaj zog heev nrog lub zog siab thiab tawv.
Tam sim no, Muaj cov ntaub ntawv tseem ceeb rau chisels: 42CrMo, 40Cr.
42CrMo4 steel yog lub zog muaj zog ultra-high steel nrog lub zog siab thiab tawv, zoo hardenability, tsis pom tseeb temper brittleness, siab qaug zog txwv thiab ntau yam cuam tshuam tsis kam tom qab quenching thiab tempering, thiab zoo kub tsis tshua muaj kev cuam tshuam toughness.Cov hlau yog tsim rau kev tsim cov yas pwm loj thiab nruab nrab uas xav tau qee lub zog thiab toughness.
Cov yam ntxwv no xyuas kom meej tias lub hardness ntawm lub tiav laum pas nrig tuaj yeem ncav cuag qib siab, tib lub sijhawm, nws muaj qhov zoo toughness thiab zoo ua haujlwm rau ntau yam kev cuam tshuam.Lub hardness ntawm lub laum pas nrig yog zoo, hnav tsis kam yog zoo, lub hardenability yog zoo, thiab lub hardness ntawm lub nto ntawm lub laum pas nrig thiab cov tub ntxhais yuav guaranteed.Qhov tsis muaj tempering brittleness txo qhov tawg ntawm lub laum pas nrig, thiab lub toughness yog zoo.Lub peev xwm yog qhov zoo, thiab nws tau lees paub tias tus Tsov tus tw ntawm lub laum pas nrig thiab lub piston tsis yooj yim los tsoo lub thaiv.Muab ua ke, nws yog ib qho khoom siv zoo tshaj plaws rau kev ua laum rods.Tab sis tus nqi ntawm cov khoom siv raw yog siab dua.Yog li ntawd, tus nqi ntawm cov pas nrig tiav yog siab dua.Txawm li cas los xij, kev ua tau zoo ntawm tus nqi yog qhov siab.
40Cr tsis yog cov hlau uas muaj zog heev
40Cr yog qhov qis dua rau 42CrMo hauv tempering brittleness, qaug zog txwv thiab tsis kam mus rau ntau yam cuam tshuam, tab sis nws muaj zoo toughness thiab hardenability.Yog li ntawd, lub brazing pas nrig ua los ntawm nws raws li ib tug raw khoom yog tsis zoo li 42CrMo nyob rau hauv cov nqe lus ntawm hnav tsis kam thiab tus Tsov tus tw.Vim nws muaj zog toughness, lub laum pas nrig tsis yooj yim rau tawg.Nyob rau tib lub sijhawm, tus nqi ntawm nws cov khoom siv raw yog qis dua 42CrMo, yog li tus nqi ntawm cov laum ua tiav yog pheej yig dua.Nws kuj yog hom nrov tshaj plaws ntawm brazing pas nrig tam sim no nyob rau hauv kev ua lag luam.Txawm li cas los xij, hauv kev ua haujlwm mine, qhov hnav yuav nrawm dua thiab lub laum pas nrig yuav softer.Nws tsis tsim nyog yog tias koj ntsib kev ua haujlwm hnyav thiab ib puag ncig.
42CrMo steel hnav tsis kam yog qhov zoo
Nws tsis yooj yim rau kev tawg thiab rhuav tshem cov thaiv, tab sis tus nqi lag luam kuj yog siab, thiab tag nrho cov nqi kev ua tau zoo yog qhov zoo tshaj plaws.Nws belongs rau qib zoo hauv kev ua lag luam tam sim no.40Cr raws li cov khoom siv raw khoom pheej yig thiab tsis yooj yim tawg, tab sis nws tsis zoo li 42CrMo hauv kev hnav tsis kam thiab tus Tsov tus tw.Tus nqi tiag tiag ntawm kev ua haujlwm ntawm kuv tsis siab tshaj 42CrMo.
