40cr 5140 Steel phaj, 65Mn phaj, astm1566, alloy steel phaj

Lus piav qhia luv luv:

40Cr steel phaj yog ib qho ntawm cov hlau siv dav tshaj plaws hauv kev lag luam kev lag luam.Tom qab quenching thiab tempering, nws muaj cov cuab yeej zoo txhua yam, zoo kub tsis tshua muaj kev cuam tshuam toughness thiab qis qis rhiab heev.Lub hardenability ntawm steel yog zoo, thiab nws yuav tsum tau quenched rau Ф 28 ~ 60mm, uas yuav tsum tau quenched rau Ф 15 ~ 40mm. Ntxiv rau quenching thiab tempering, cov hlau no kuj haum rau cyanidation thiab siab zaus quenching.Kev ua haujlwm txiav yog qhov zoo.Thaum lub hardness yog hb174 ~ 229, tus txheeb ze machinability yog 60%.Cov hlau yog tsim los ua cov yas pwm nruab nrab.

Product Description

40Cr belongs rau gb3077 "alloy structural steel".Qhov txawv yog tom qab kev kho cua sov.Lub luag haujlwm tseem ceeb ntawm Cr hauv kev kho cua sov yog los txhim kho lub hardenability ntawm hlau.Vim yog kev txhim kho ntawm hardenability, cov khoom siv xws li lub zog, hardness thiab cuam tshuam toughness ntawm 40Cr tom qab quenching (los yog quenching thiab tempering) kev kho mob kuj tseem muaj ntau dua li ntawm 45 steel.Txawm li cas los xij, vim muaj zog hardenability, qhov kev ntxhov siab sab hauv ntawm 40Cr thaum lub sij hawm quenching yog ntau dua li ntawm 45 steel.Nyob rau hauv tib yam kev mob, qhov tawg inclination ntawm 40Cr cov khoom yog ntau dua li ntawm 45 steel.Yog li ntawd, txhawm rau kom tsis txhob ua haujlwm tawg, 40Cr quenching feem ntau siv cov roj uas tsis muaj thermal conductivity raws li qhov nruab nrab quenching (qee zaum ob txoj kev ua kua quenching kuj siv, raws li cov lus hais mus, dej quenching roj txias), thaum 45 steel siv dej nrog siab. thermal conductivity raws li qhov nruab nrab quenching.
