Kwinjineli nakwimveliso, amandla yinto ethatha isigqibo. Nokuba yi-crankshaft kwi-injini yeemoto okanye isikhonkwane esinomthwalo ophezulu kwisixhobo sokwakha, ukomelela kwe-tensile kuqinisekisa ukuba ungakanani na umthwalo onokuwuphatha phambi kokwaphuka. Phakathi kweentsimbi ezininzi zealloy ezikhoyo,4140 intsimbi yentsimbiizuze udumo ngokulingana kwayo okuchukumisayo kokuqina, ukuqina, kunye nobuchule.
Kodwa yomelele kangakanani i-4140 alloy steel-ngokwenene? Kweli nqaku,sakysteeluntywila nzulu kwiipropathi eziqinile ze-4140, ijonga ukuba yintoni eyenza ibe yimathiriyeli ethembekileyo ekufuneni usetyenziso lwesakhiwo kunye noomatshini.
Yintoni i-4140 Alloy Steel?
4140 nguintsimbi ephantsi ye-chromium-molybdenumeyaziwa ngamandla ayo aphezulu kunye nokumelana nokudinwa okuhle. Isetyenziswa kakhulu kwimveliso, umatshini, izixhobo, kunye nezinto ezinobunzima.
Ukwakhiwa kweekhemikhali eziphambili ze-4140 kubandakanya:
-
Ikhabhoni:0.38% - 0.43%
-
I-Chromium:0.80% - 1.10%
-
I-Molybdenum:0.15% - 0.25%
-
IManganese:0.75% - 1.00%
-
Isilicon:0.15% - 0.35%
Ezi zinto zokudibanisa ziphucula ukuqina kunye namandla, okwenza i-4140 enye yezona zintsimbi ezithembekileyo zokusetyenziswa kwesakhiwo.
Ukuqonda Amandla Okuqina
Tensile strengthibhekisa kubuninzi bobunzima bokuqina (ukutsala okanye ukolula) uxinzelelo olunokuthi lunyamezeleke phambi kokusilela. Idla ngokulinganiswaii-megapascals (MPa) or iiponti nge-intshi nganye (psi). Amandla okuqina aphezulu athetha ukuba izinto eziphathekayo zinokumelana namandla amakhulu ngaphambi kokonakala okanye ukwaphuka.
Amandla e-Tensile ye-4140 Alloy Steel
Amandla okuqina kwentsimbi ye-4140 ixhomekeke kakhulu kwimeko yonyango lobushushu:
1. Imeko eAnealed
Kwimeko yayo ethambileyo (i-annealed), i-4140 yentsimbi ihlala ibonelela:
-
Tensile strength:655 - 850 MPa
-
Unikeze Amandla:415 – 620 MPa
-
Ukuqina:~197 HB
2. Imeko eqhelekileyo
Emva kokuqheleka, ubume bentsimbi buba bufanayo, buphucula iimpawu zoomatshini:
-
Tensile strength:850 - 1000 MPa
-
Unikeze Amandla:650 - 800 MPa
-
Ukuqina:~220 HB
3. Ucinyiwe kwaye Unomsindo (Q&T)
Le yeyona meko ixhaphakileyo kwizicelo ezisebenza kakhulu:
-
Tensile strength:1050 - 1250 MPa
-
Unikeze Amandla:850 - 1100 MPa
-
Ukuqina:28 – 36 HRC
At sakysteel, sinikezela4140 intsimbi yentsimbikwiimeko ezahlukeneyo eziphathwe ubushushu, zilungiselelwe ukuhambelana neemfuno ezithile zamandla kumashishini ahlukeneyo.
Kutheni le nto i-4140's Tensile Amandla iphezulu kangaka?
Izinto eziphambili emva kokuqina okuphezulu kwe-4140 ziquka:
-
Umxholo weChromium:Yongeza ubunzima kunye nokumelana nokunxiba
-
I-Molybdenum:Ukuphucula amandla kumaqondo obushushu aphezulu kunye nokwandisa ukuqina
-
Ububhetyebhetye kuNyango loBubushushu:Ukuthunga i-microstructure ukuze ihambelane namandla afunekayo kunye nokuqina
-
iNqanaba leKhabhoni elilungelelanisiweyo:Inika indibaniselwano elungileyo yamandla kunye ne-ductility
Ezi mpawu zivumela i-4140 ukuba iphumelele iintsimbi ezininzi zekhabhoni kunye nezinye izixhobo zentsimbi xa kuziwa kumandla obunzima phantsi komthwalo.
Ingaba i-4140 ithelekiswa njani nezinye iintsimbi?
4140 vs 1045 Carbon Steel
-
I-1045 yintsimbi ephakathi kwekhabhoni enamandla okuqina malunga ne-570 - 800 MPa.
-
I-4140 inikezela nge-30% ukuya kwi-50% yamandla angaphezulu, ngakumbi xa iphathwa ngubushushu.
