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 tauri da kuma low daraja sensitivity.Good karfe hardenability, lokacin da ruwa quench. hardening zuwa Ф 28 ~ 60 mm, lokacin da man fetur quenching hardening zuwa Ф 15 ~ 40 mm. Ƙarfe kuma ya dace da cyanidation da kuma yawan adadin mita. Lokacin da taurin ya kasance 174 ~ 229HB, ma'anar dangi shine 60% karfe ya dace. don yin matsakaici - masu girman filastik.

Medium carbon tempered karfe, sanyi heading mutu steel.The karfe ne na matsakaici price, sauki aiwatar da zai iya samun wasu tauri, plasticity da abrasion juriya bayan dace zafi treatment.Normalizing iya inganta sabon yi na blank ta inganta microstructure tacewa da kuma gabatowa da ma'auni jihar.Tempered a 550 ~ 570 ℃, da karfe yana da mafi m inji Properties.The hardenability na karfe ne mafi girma fiye da 45 karfe, dace da high 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 juya jiki sassa, wanda tsawon wanda ya fi girma da diamita, kullum hada concentric shaft cylindrical. surface, conical surface, ciki rami da zaren da daidai karshen surface. Bisa ga daban-daban siffar da tsarin, shaft sassa za a iya raba zuwa na gani shaft, mataki shaft, m shaft 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.Wannan shi ne 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. Za a kawo shi cikin wasa, ana aiwatar da jiyya mai tsayin mita mai tsayi bayan yanayin yanayin 40Cr, tare da taurin har zuwa 55-58hrc, don samun taurin saman da ake buƙata da kuma kula da kyakkyawar taurin zuciya.
