Intsimbi ye-4140 yintsimbi ethandwayo yealloy eyaziwa ngamandla ayo, ukuqina, kunye nokuguquguquka. Iphuma kwintsapho yeentsimbi ze-chromium-molybdenum, enikezela indibaniselwano ekhethekileyo yeempawu zomatshini ezenza kube yinto ekhethwayo kwizicelo zoshishino. Iinjineli, abavelisi, kunye nabavelisi bayisebenzisa ngokubanzi le ntsimbi kuyo yonke into ukusuka kumalungu emoto ukuya kwizinto zoomatshini.
Kweli nqaku le-SEO, i-sakysteel inika umbono obanzi we4140 intsimbi, kubandakanywa ukubunjwa kweekhemikhali, iipropati zomatshini, iinkqubo zonyango lokushisa, kunye nokusetyenziswa okuqhelekileyo.
Ukuhlelwa kwe-4140 Steel
I-4140 yintsimbi ephantsi ye-alloy ewela phantsi kwenkqubo yokuhlelwa kwe-SAE-AISI. Ikwabizwa ngokubaI-AISI 4140, EN19 (eYurophu), kwayeI-SCM440 (eJapan). Igama elithi “4140” libhekisa kumxholo othile wealloyi:
-
"41" ibonisa intsimbi ye-chromium-molybdenum
-
"40" imele i-carbon content (0.40%).
Intsimbi ye-4140 ayiyiyo insimbi engenasici, njengoko ingenayo i-chromium eyaneleyo yokubonelela ukuxhathisa ukubola. Endaweni yoko, ixabiswa ngenxa yokuqina kwayo koomatshini kunye nobunzima emva konyango lobushushu.
Ukubunjwa kweMichiza ye-4140 Steel
Ukwakhiwa kweekhemikhali ze-4140 yiyona nto inika iimpawu zayo eziphuculweyo zomatshini. Uluhlu oluqhelekileyo lubandakanya:
-
Ikhabhoni (C):0.38% - 0.43%
-
I-Chromium (Cr):0.80% - 1.10%
-
IManganese (Mn):0.75% - 1.00%
-
I-Molybdenum (Mo):0.15% - 0.25%
-
Isilicon (Si):0.15% - 0.35%
-
I-Phosphorus (P):≤ 0.035%
-
Isulfure (S):≤ 0.040%
Ezi zinto zisebenza kunye ukukhulisa ukuqina, ukuxhathisa ukunxiba, kunye nokuqina kukonke, ukwenza i-4140 ibe yimathiriyeli yokuya kufuna iindawo ezinomatshini.
Iipropati zoomatshini ze-4140 Steel
I-4140 inikezela ngoluhlu olunomtsalane lweempawu zoomatshini, ngakumbi emva konyango olufanelekileyo lobushushu. Ezi ziquka:
-
Tensile strength:Ukuya kuthi ga kwi-1100 MPa (160 ksi)
-
Unikeze Amandla:Malunga ne-850 MPa (123 ksi)
-
Ukwandiswa ngexesha lekhefu:Malunga nama-20%
-
Ukuqina:Ngokuqhelekileyo i-197 ukuya kwi-235 HB ikwimeko ye-annealed, ukuya kuthi ga kwi-50 HRC emva kokucima kunye nokuvutha
Ezi xabiso zinokuhluka ngokuxhomekeka kwifom yentsimbi (ibha, ipleyiti, i-forged) kunye nemeko yonyango lokushisa.
Unyango lobushushu lwe-4140 Steel
Unyango lobushushu yinkqubo ephambili eyandisa ukusebenza kwe4140 intsimbi. Intsimbi inokungena ezi nkqubo zilandelayo:
-
Ukuhlaziya
Ukupholisa kancinane ukusuka malunga ne-850 ° C ukuphucula ubuchule kunye nokunciphisa uxinzelelo lwangaphakathi. Oku kubangela ulwakhiwo oluthambileyo kunye ne-ductility ephuculweyo. -
Ukuqheleka
Kufudunyezwe ukuya kutsho kuma-870°C ukucokisa ubume beenkozo. Ibonelela ngokulinganisela kwamandla kunye nokuqina. -
Ukunciphisa kunye nokunciphisa
Iqiniswe kukufudumeza ukuya kuma-845°C kwaye iphole ngokukhawuleza kwi-oyile okanye emanzini, ilandelwe kukufudumeza kumanqanaba obunzima obufunekayo. Oku kwandisa kakhulu amandla kunye nokumelana nokunxiba. -
Ukunciphisa Uxinzelelo
Kwenziwe malunga ne-650 ° C ukunciphisa uxinzelelo olushiyekileyo oluvela kumatshini okanye ukuwelda.
Kwi-sakysteel, sibonelela4140 intsimbikwiimeko ezahlukeneyo zokuphathwa kobushushu ngokusekelwe kwiimfuno zabathengi, ukuqinisekisa ukusebenza okuphezulu kwisicelo sakho.
