I-4140 Alloy Steel Tensile: Iqine Kangakanani Ngempela?

Kwezobunjiniyela nakwezokukhiqiza, amandla ayisici esinqumayo. Noma ngabe i-crankshaft enjinini yezimoto noma iphinikhodi enomthwalo omkhulu kumishini yokwakha, amandla aqinile anquma ukuthi ungakanani umthwalo ongawuthwala ngaphambi kokuphuka. Phakathi kwezinsimbi eziningi ze-alloy ezitholakalayo,4140 ingxubevange yensimbiizuze idumela ngokulinganisela kwayo okumangazayo yamandla aqinile, ukuqina, kanye nobuciko.

Kepha iqine kangakanani i-4140 alloy steel-ngempela? Kulesi sihloko,sakysteelingena ijule ezintweni eziqinile ze-4140, ihlola ukuthi yini eyenza ibe yinto ethenjwayo ekufuneni izinhlelo zokusebenza zesakhiwo nemishini.

Iyini i-4140 Alloy Steel?

4140 ngiinsimbi ephansi ye-chromium-molybdenumeyaziwa ngamandla ayo aphezulu okudonsa kanye nokumelana nokukhathala okuhle. Isetshenziswa kabanzi ekukhiqizeni, ekukhiqizeni, ekusetshenzisweni kwamathuluzi, nasezintweni ezisindayo.

Ukwakhiwa kwamakhemikhali angukhiye we-4140 kuhlanganisa:

  • Ikhabhoni:0.38% - 0.43%

  • I-Chromium:0.80% - 1.10%

  • I-Molybdenum:0.15% - 0.25%

  • I-Manganese:0.75% - 1.00%

  • I-silicon:0.15% - 0.35%

Lezi zakhi ze-alloying zithuthukisa ukuqina namandla, okwenza i-4140 ibe yinye yezinsimbi ezinokwethenjelwa kakhulu ekusetshenzisweni kwesakhiwo.

Ukuqonda Amandla Aqinile

Amandla aqinileisho inani eliphakeme lokudonsa (ukudonsa noma ukwelula) ingcindezi into engabekezelela ngaphambi kokuba ihluleke. Ngokuvamile kukalwa ngoama-megapascals (MPa) or amaphawundi nge-intshi yesikwele (psi). Amandla aqine kakhulu asho ukuthi into ingakwazi ukumelana namandla amakhulu ngaphambi kokonakala noma ukuphuka.

I-Tensile Strength ye-4140 Alloy Steel

Amandla okuqina wensimbi engu-4140 ancike kakhulu esimweni sayo sokwelashwa kokushisa:

1. I-Annealed Condition

Esimeni sayo esithambile kakhulu (i-annealed), i-4140 steel ngokuvamile inikeza:

  • Amandla Okuqina:655 - 850 MPa

  • Amandla Okukhiqiza:415 – 620 MPa

  • Ukuqina:~ 197 HB

2. Isimo Esijwayelekile

Ngemuva kokujwayelekile, ukwakheka kwensimbi kuba okufanayo, kuthuthukise izakhiwo zemishini:

  • Amandla Okuqina:850 - 1000 MPa

  • Amandla Okukhiqiza:650 - 800 MPa

  • Ukuqina:~ 220 HB

3. I-Quenched and Tempered (Q&T)

Lesi yisimo esivame kakhulu sezinhlelo zokusebenza ezisebenza kahle kakhulu:

  • Amandla Okuqina:1050 - 1250 MPa

  • Amandla Okukhiqiza:850 - 1100 MPa

  • Ukuqina:28 – 36 HRC

At sakysteel, sinikeza4140 ingxubevange yensimbiezimweni ezihlukahlukene ezilashwa ngokushisa, ezilungiselelwe ukufanisa izidingo ezithile zamandla ezimbonini ezahlukene.

Kungani Amandla E-4140's Tensile Aphezulu Kangaka?

Izici ezibalulekile ngemuva kwamandla aphezulu we-4140 zifaka:

  • Okuqukethwe kwe-Chromium:Ingeza ubulukhuni nokumelana nokugqoka

  • I-Molybdenum:Ithuthukisa amandla emazingeni okushisa aphezulu futhi ithuthukise ukuqina

  • Ukuguquguquka Kokwelashwa Kokushisa:I-Tailor microstructure ukuze ihambisane namandla nokuqina okufunayo

  • Izinga Lekhabhoni Elilinganisiwe:Inikeza inhlanganisela enhle yamandla kanye ne-ductility

Lezi zici zivumela i-4140 ukuthi idlule izinsimbi eziningi ze-carbon ngisho nezinsimbi zamathuluzi uma kuziwa emandleni aqinile ngaphansi komthwalo.

I-4140 iqhathaniswa kanjani nezinye izinsimbi?

4140 vs 1045 Carbon Steel

  • I-1045 iyinsimbi ye-carbon emaphakathi enamandla aqinile azungeze ama-570 - 800 MPa.

  • I-4140 inikeza amandla angu-30% kuya kwangu-50% ngaphezulu, ikakhulukazi uma iphathwa ngokushisa.

4140 vs 4340 Insimbi

  • I-4340 ifaka i-nickel, ekhulisa ukuqina nokumelana nokukhathala.

  • Nakuba i-4340 ingase inikeze ukuqina okuphezulu kancane, i-4140 iyonga kakhulu ngokusebenza okufanayo okuqinile.

4140 vs Stainless Steel (isb, 304, 316)

  • Izinsimbi ezingenasici ze-Austenitic zinikeza ukumelana nokugqwala kodwa amandla aphansi okuqinile (imvamisa engu-~500 - 750 MPa).

  • I-4140 icishe iqine ngokuphindwe kabili kodwa kufanele ivikelwe ekugqwaleni ezindaweni ezinolaka.

Izinhlelo zokusebenza ezincike ku-4140's Tensile Strength

Ngenxa yamandla ayo aphezulu, i-4140 isetshenziswa kakhulu ezingxenyeni ezibekezelela imithwalo esindayo noma amandla ashukumisayo. Izinhlelo zokusebenza ezijwayelekile zifaka:

Ezezimoto

  • Shaft shafts

  • Ama-Crankshafts

  • Izingxenye zokumiswa

  • Izikhala zamagiya

Amafutha Negesi

  • Dweba amakholomu

  • Amalunga ethuluzi

  • Imizimba ye-valve

  • Ukufakwa kweHydraulic

I-Aerospace

  • Izingxenye zegiya lokuhlala

  • Abakaki bokusekela injini

  • Izixhumanisi eziqondile

Ithuluzi & Die

  • Izibhakela futhi uyafa

  • Abaphathi bamathuluzi

  • Amathuluzi okwakha

Ikhono lokumelana nemithwalo emile kanye ne-cyclic lenza4140umgogodla wezingxenye ezibalulekile ezingenakubalwa ezimbonini zomhlaba.

Izici Ezithonya Amandla Aqinile Ekuqeqesheni

Amandla e-theoretical tensile we-4140 angahluka ezinhlelweni zomhlaba wangempela ngokusekelwe kulokhu:

  • Usayizi wengxenye:Izingxenye eziphambanayo ezinkulu zingapholisa kancane phakathi nokwelashwa kokushisa, zehlise ubulukhuni.

  • Ukuqedwa kobuso:Ukuqedwa okuqinile kungasebenza njengokukhuphuka kwengcindezi.

  • Imisebenzi yomshini:Ukwenza imishini engalungile kungadala ukugxila kwengcindezi.

  • Ukulawula ukwelashwa kokushisa:Amazinga okushisa okucisha okunembayo nawokuthambisa athinta ngokuqondile amandla okugcina.

At sakysteel, sisebenzisa ukulawulwa kwekhwalithi okuqinile ngesikhathi sokwelashwa kokushisa nokwenza imishini ukuze siqinisekise izakhiwo eziqinile nezingaguquki kuyo yonke imikhiqizo yethu yensimbi engama-4140.

Ukuhlola kanye Nezitifiketi

Amandla okuqina ngokuvamile akalwa kusetshenziswa aumshini wokuhlola wendawo yonke (UTM)ukulandela amazinga e-ASTM noma e-ISO. Isampula yensimbi yeluliwe kuze kube yilapho iphuka, futhi imiphumela irekhodwa.

KonkesakysteelIzinto zensimbi ezingama-4140 zinganikezwa:

  • I-EN 10204 3.1 izitifiketi

  • Imibiko yokuhlolwa komshini

  • Idatha yokwakheka kwamakhemikhali

Lokhu kuqinisekisa ukuba sobala okuphelele nokuhambisana nezinkambiso zemboni.

Imicabango yokugcina

4140 ingxubevange yensimbiingenye yezinsimbi eziguquguqukayo neziqinile ezitholakala emakethe yomhlaba. Ngamandla aqinile adlula i-1000 MPa ezimeni zokwelashwa, ihlangabezana nezidingo ezidingekayo zezinhlelo zokusebenza zesakhiwo, ezomshini, nezamathuluzi.

Lapho amandla, ukuqina, nokusebenza kubaluleke kakhulu,4140 okulethwayo-futhisakysteeliqinisekisa ukuthi uthola kuphela okokusebenza kwekhwalithi ephezulu kakhulu, okuhloliwe futhi kwaqinisekiswa ngokuthula kwakho kwengqondo.
