abu 40cr

40Cr ne GB misali karfe lambar a kasar Sin, da kuma 40Cr karfe ne daya daga cikin mafi yadu amfani karfe a inji masana'antu masana'antu.It yana da kyau m inji Properties, mai kyau low zafin jiki tasiri taurin da low daraja ji.Good karfe hardening, a lokacin da ruwa quench hardening to Ф 28 ~ 60 mm, a lokacin da man fetur quenching hardening Ф0 zuwa karfe Ф0. da kuma babban mitar quenching.Lokacin da taurin shine 174 ~ 229HB, ma'anar dangi shine 60% . Karfe ya dace don yin matsakaici - girman filastik filastik.

Medium carbon tempered karfe, sanyi heading mutu steel.The karfe ne na matsakaici price, sauki aiwatar da kuma iya samun wasu tauri, plasticity da abrasion juriya bayan dace zafi magani.Normalizing iya inganta sabon yi na blank ta inganta microstructure tacewa da kuma gabatowa da ma'auni state.Tempered a 550 ~ 570 karfe yana da mafi kyaun karfe 350 ~ 570 ℃. sama da 45 karfe, dace da babban mita quenching, harshen wuta quenching da sauran surface hardening magani.

Shaft sassa ne daya daga cikin hankula sassa sau da yawa ci karo a machines.It ne yafi amfani da su goyi bayan watsa aka gyara, canja wurin karfin juyi da load.Shaft sassa suna jujjuya jiki sassa, da tsawon wanda shi ne mafi girma fiye da diamita, kullum hada concentric shaft cylindrical surface, conical surface, ciki rami da zare da daidai karshen surface.A cewar ga daban-daban siffar shaft shaft tsarin, za a iya raba shaft shaft tsarin, a cikin daban-daban siffar shaft tsarin, shaft shaft tsarin. da crankshaft.

40Cr abu ne na gama gari na sassan shaft. Yana da arha kuma yana iya samun kyakkyawan aikin yanke bayan quenching da tempering (ko daidaitawa), kuma yana iya samun ingantattun kaddarorin inji kamar ƙarfi da tauri. Bayan quenching, da surface taurin iya isa 45 ~ 52HRC.

40Cr ana amfani dashi sosai a masana'antar injiniya. Irin wannan karfe yana da kyau inji Properties.This ne wani matsakaici carbon gami karfe da mai kyau quenching yi, 40Cr za a iya taurare zuwa HRC45 ~ 52. Saboda haka, idan surface taurin bukatar da za a inganta da m inji Properties na 40Cr ana sa ran da za a kawo a cikin play, da surface high-mita quenching magani ne sau da yawa za'ayi bayan da taurin harsashi da 40Cr. 55-58hrc, don samun babban taurin da ake buƙata da kuma kula da kyakkyawar taurin zuciya.
