Kubunjineli nakwimveliso, amandla yinto ebalulekileyo. Nokuba yi-crankshaft kwinjini yemoto okanye iphini yomthwalo ophezulu kwizixhobo zokwakha, amandla okutsalwa amisela ukuba ingakanani umthwalo onokuwuthwala ngaphambi kokuba uqhekeke. Phakathi kweentsimbi ezininzi ze-alloy ezikhoyo,Intsimbi ye-alloy engu-4140ifumene udumo ngokulinganisela kwayo okumangalisayo kwamandla okutyhafa, ukuqina, kunye nokusebenza kakuhle koomatshini.
Kodwa iqine kangakanani intsimbi ye-alloy ye-4140—ngokweneneKweli nqaku,i-sakysteelingena nzulu kwiimpawu zokuxinana ze-4140, ihlola ukuba yintoni eyenza ukuba ibe yinto ethembekileyo kwizicelo ezifuna ulwakhiwo kunye noomatshini.
Yintoni i-4140 Alloy Steel?
I-4140 yiintsimbi ye-chromium-molybdenum ene-alloy ephantsiyaziwa ngamandla ayo aphezulu okutyhala kunye nokumelana kakuhle nokudinwa. Isetyenziswa kakhulu kwimveliso, ekuchweni, kwizixhobo, nakwizinto ezinzima.
Ulwakhiwo oluphambili lweekhemikhali ze-4140 luquka:
-
Ikhabhoni:0.38% – 0.43%
-
I-Chromium:0.80% – 1.10%
-
I-Molybdenum:0.15% – 0.25%
-
IManganese:0.75% – 1.00%
-
I-silicon:0.15% – 0.35%
Ezi zinto zokudibanisa ziqinisa ukuqina nokuqina, nto leyo eyenza i-4140 ibe yenye yezona ntsimbi zithembekileyo zokusetyenziswa kwesakhiwo.
Ukuqonda Amandla Okuxinana
Tensile strengthibhekisa kubuninzi boxinzelelo oluxinzelelweyo (lokutsala okanye lokuzolula) olunokuthi lunyamezeleke ngaphambi kokuba luhluleke. Luhlala lulinganiswaii-megapascals (MPa) or iiponti nge-intshi yesikwere (psi)Amandla aphezulu okuxinana athetha ukuba izinto zinokumelana namandla amakhulu ngaphambi kokuba zijike okanye ziqhekeke.
Amandla okuThamba e-4140 Alloy Steel
Amandla okutsalwa kwentsimbi ye-4140 axhomekeke kakhulu kwimeko yayo yonyango lobushushu:
1. Imeko eNgxotshiweyo
Kwimeko yayo ethambileyo (efakwe intsimbi), intsimbi ye-4140 idla ngokunika:
-
Tensile strength:655 – 850 MPa
-
Unikeze Amandla:415 – 620 MPa
-
Ubunzima:~197 HB
2. Imeko Eqhelekileyo
Emva kokulungiswa, ulwakhiwo lwentsimbi luba yinto efanayo ngakumbi, nto leyo ephucula iipropati zoomatshini:
-
Tensile strength:850 – 1000 MPa
-
Unikeze Amandla:650 – 800 MPa
-
Ubunzima:~220 HB
3. Ukucima kunye nokulinganisela (Q&T)
Le yeyona meko ixhaphakileyo kwizicelo ezisebenza kakuhle:
-
Tensile strength:1050 – 1250 MPa
-
Unikeze Amandla:850 – 1100 MPa
-
Ubunzima:28 – 36 HRC
At i-sakysteel, sinikezelaIntsimbi ye-alloy engu-4140kwiimeko ezahlukeneyo ezinyangwa ngobushushu, zenzelwe ukuhambelana neemfuno ezithile zamandla kumashishini ahlukeneyo.
Kutheni i-4140's 4140's inamandla okutyhafa kangaka?
Izinto eziphambili ezibangela amandla aphezulu okutsalwa kwe-4140 ziquka:
-
Umxholo weChromium:Yongeza ubulukhuni kunye nokumelana nokuguguleka
-
I-Molybdenum:Iphucula amandla xa kushushu kakhulu kwaye iphucula ukuqina kwayo
-
Ukuguquguquka koNyango loBushushu:Yenza ulwakhiwo oluncinci ukuze luhambelane namandla kunye nokuqina okufunwayo
-
Inqanaba leKhabhoni eliLungelelanisiweyo:Inika indibaniselwano elungileyo yamandla kunye nokuguquguquka
Ezi mpawu zivumela i-4140 ukuba iphumelele ngaphezu kweentsimbi ezininzi zekhabhoni kwanezinye izixhobo xa kufikwa kumandla okuxinana phantsi komthwalo.
Ithelekiswa njani i-4140 nezinye iintsimbi?
Intsimbi yeCarbon engu-4140 vs 1045
-
I-1045 yintsimbi yekhabhoni ephakathi enamandla okutsalwa amalunga ne-570 ukuya kwi-800 MPa.
-
I-4140 inika amandla angaphezulu angama-30% ukuya kuma-50%, ingakumbi xa inyangwa ngobushushu.
