40Cr 5140 41cr4 Kub Rolled Seamless Steel Yeeb Nkab Astm T91 Boiler Tube Seamless Alloy Steel Pipe P11 Alloy Steel Tube

Lus piav qhia luv luv:

40Cr steel yog ib qho ntawm cov hlau siv dav tshaj plaws hauv kev tsim khoom siv tshuab.Tom qab quenching thiab tempering, nws muaj cov cuab yeej zoo txhua yam, zoo kub tsis tshua muaj kev cuam tshuam toughness thiab tsis tshua muaj notch rhiab heev.Lub hardenability ntawm cov hlau yog zoo, thiab nws yuav quenched mus rau qhov siab tshaj plaws thaum dej quenched Ф 28 ~ 60mm, roj quenched rau Ф 15～40 mm.Thaum lub hardness yog 174 ~ 229hb, tus txheeb ze machinability yog 60%.Cov hlau yog tsim los ua cov yas pwm nruab nrab.

Product Description

40Cr belongs rau nruab nrab carbon quenched thiab tempered steel thiab txias taub hau tuag steel.Cov hlau muaj tus nqi nruab nrab thiab kev ua haujlwm yooj yim.Tom qab kev kho cua sov kom zoo, nws tuaj yeem tau txais qee qhov toughness, plasticity thiab hnav tsis kam.Normalizing tuaj yeem txhawb kev ua kom zoo ntawm cov qauv, ze rau lub xeev sib npaug, thiab txhim kho qhov kev ua tau zoo ntawm qhov khoob.Thaum tempered ntawm 550 ~ 570 ℃, cov hlau muaj qhov zoo tshaj plaws txhua yam khoom siv.Lub hardenability ntawm cov hlau yog siab dua li ntawm 45 steel, uas yog haum rau kev kho deg hardening xws li high zaus quenching thiab nplaim quenching.40Cr ncej ib feem yog ib qho ntawm feem ntau ntsib hauv tshuab.Nws yog tsuas yog siv los txhawb qhov kis tau tus mob, hloov torque thiab dais load.

Khoom siv

40Cr thiab lwm yam alloy steels yog tsim rau cov ncej nrog nruab nrab precision thiab siab ceev.Tom qab quenching, tempering thiab quenching, cov hlau no muaj cov khoom siv zoo dua qub.Tom qab quenching thiab tempering, cov hlau zoo li no yog siv los ua cov khoom siv kho tshuab uas tuaj yeem nqa nruab nrab thiab nruab nrab ceev, xws li lub kauj khawm, lub nraub qaum ib nrab ntawm lub tsheb, iav, ncej, cua nab, spline ncej thiab lub tes tsho sab saum toj ntawm lub tshuab cuab yeej.
