ua 40cr

40Cr yog GB tus qauv steel tooj nyob rau hauv Suav teb, thiab 40Cr steel yog ib tug ntawm cov feem ntau lug siv hlau nyob rau hauv mechanical manufacturing kev lag luam.Nws muaj zoo tag nrho cov neeg kho tshuab zog, zoo kub tsis tshua muaj kev cuam tshuam toughness thiab tsis tshua muaj notch rhiab heev.Zoo steel hardenability, thaum dej quench hardening rau Ф 28 ~ 60 hli, thaum roj quenching yog tsim nyog rau Ф 28 ~ 60 hli. cyanidation thiab high zaus quenching.Thaum lub hardness yog 174 ~ 229HB, tus txheeb ze machinability yog 60%.

Qhov nruab nrab carbon tempered steel, txias taub hau tuag steel.Cov hlau yog tus nqi nruab nrab, yooj yim rau kev ua haujlwm thiab tuaj yeem tau txais qee qhov toughness, plasticity thiab abrasion tsis kam tom qab kev kho cua sov kom zoo.Normalizing tuaj yeem txhim kho qhov kev ua tau zoo ntawm cov dawb paug los ntawm kev txhawb nqa microstructure refinement thiab mus txog lub xeev sib npaug. cov hlau yog siab tshaj 45 steel, haum rau high zaus quenching, nplaim quenching thiab lwm yam nto hardening kho.

Ncej qhov chaw yog ib qho ntawm cov khoom feem ntau ntsib hauv cov tshuab.Nws yog siv los txhawb cov khoom sib kis, hloov torque thiab load.Ncaj qhov chaw yog rotating lub cev qhov chaw, qhov ntev ntawm uas yog ntau tshaj li txoj kab uas hla, feem ntau yog tsim los ntawm concentric ncej cylindrical nto, conical nto, sab hauv lub qhov thiab cov xov thiab qhov sib thooj ntawm qhov kawg ntawm cov qauv tuaj yeem muab faib ua qhov sib txawv. optical ncej, kauj ruam ncej, hollow ncej thiab crankshaft.

40Cr yog ib qho khoom siv ntawm cov ncej ncej. Nws yog pheej yig thiab tuaj yeem tau txais kev ua haujlwm zoo dua tom qab quenching thiab tempering (lossis normalizing), thiab tuaj yeem tau txais cov khoom zoo dua qub xws li lub zog thiab tawv. Tom qab quenching, qhov tawv tawv tuaj yeem ncav cuag 45 ~ 52HRC.

40Cr yog siv dav hauv kev tsim khoom. Cov hlau no muaj cov khoom zoo txhua yam.Qhov no yog ib qho nruab nrab carbon alloy steel nrog zoo quenching kev ua tau zoo, 40Cr yuav hardened rau HRC45 ~ 52.Yog li ntawd, yog hais tias lub deg hardness yuav tsum tau txhim kho thiab superior mechanical zog ntawm 40Cr yuav tsum tau coj mus rau hauv kev ua si, lub nto high-frequency quenching kev kho mob yog feem ntau nqa tawm tom qab 55-8 hrc nrog txias txias. thiaj li tau txais qhov yuav tsum tau muaj qhov siab hardness thiab tswj lub siab toughness zoo.
