4140 ʻAʻahu Paʻa Paʻa: Pehea ʻOiaʻiʻo?

I nā ʻoihana kahi e hoʻomau ai nā ʻāpana metala i ka hakakā, ka hopena, a me ka abrasion i kēlā me kēia lā,ʻaʻahu kūʻēlilo i waiwai ko'iko'i. Inā ʻo ke kaʻa kaʻa ma lalo o ka haʻahaʻa kaumaha a i ʻole nā kumu e hoʻomau mau ana i ka neʻe ʻana, pono e hana ʻia nā ʻāpana mai nā mea paʻakikī a mau loa. ʻO kekahi o nā kila hilinaʻi nui ma kēia kahua4140 kila kila.

ʻIke ʻia no kona ikaika ikaika a me ka paʻakikī, hoʻohanohano ʻo 4140 i ke kūpaʻa maikaʻi ʻana i ka ʻaʻahu - ke hana pololei ʻia.sakysteelʻimi i ka paʻakikī o ke kila 4140 i ka wā e kūʻē ai i ka ʻaʻahu, a no ke aha he mea kūpono ia no nā noi hoʻoluhi kiʻekiʻe.

He aha ka 4140 Steel?

ʻO 4140 kahichromium-molybdenum kila haʻahaʻae hāʻawi ana i kahi hui kūʻokoʻa o ka ikaika, ka paʻakikī, ka paʻakikī, a me ke kūpaʻa ʻana. Aia ia i ka AISI-SAE steel grading system a hoʻohana mau ʻia i ka hana ʻana i nā ʻāpana kikoʻī, nā mīkini hana kaumaha, a me nā mea hana.

Hoʻohui kemika maʻamau:

  • Kalapona: 0.38 – 0.43%

  • Chromium: 0.80 – 1.10%

  • Manganese: 0.75 - 1.00%

  • Molybdenum: 0.15 – 0.25%

  • Silika: 0.15 – 0.35%

Hoʻonui ka chromium i ka paʻakikī a me ke kūpaʻa ʻana, aʻo ka molybdenum e hoʻonui i ka paʻakikī a me ka ikaika wela. Hana kēia mau mea hoʻohui4140 kilakūpono no nā ʻāpana e kūʻē i ka pōʻino o ka ʻili no nā manawa lōʻihi.

He aha ka Wear Resistance?

ʻAʻahu kūʻēhe mea hiki ke pale i ka poho o ka ili ma muli o ka hana mechanical. Hiki i kēia hana ke komo:

  • Abrasion(ʻōniʻoniʻo, ʻōpala)

  • Hoʻopili(ka hoʻoili pili ʻana o ka mea)

  • ʻAi ʻino(ka hopena o nā ʻāpana a i ʻole ka wai)

  • Huhū(nā micro-neʻe ma lalo o ka ukana)

ʻO ke kūpaʻa ʻaʻahu kiʻekiʻe, ʻo ia ka mea e lōʻihi ka lōʻihi o ka lawelawe ʻana, e hōʻemi ana i nā kumukūʻai mālama a me ka manawa haʻahaʻa.

Pehea e hana ai ʻo 4140 Steel i ka pale ʻana?

ʻAʻole ʻo 4140 ka kila ʻoi aku ka paʻakikī ma ka mākeke, akā ʻo kona kūpaʻa ʻanahiki ke maʻalahi. Ma o ka ponolapaʻau wela, Hiki ke ho'ololi 'ia kēia kila mai kahi mea machinable, 'ano ikaika-ikaika i loko o ka hale mana pa'a 'ole.

1. Ma ke kūlana Annealed

  • Maʻalahi a maʻalahi i ka mīkini

  • 'Oolea ha'aha'a (~197 HB)

  • He haʻahaʻa haʻahaʻa ke kūpale ʻaʻahu

  • He kūpono no ka hana hou ʻana e like me ka mīkini a welding

2. Ma hope o ka hoʻopaʻa ʻana a me ka hoʻopaʻa ʻana

  • Hoʻonui nui i ka paʻakikī o ka ʻili (a hiki i 50 HRC)

  • ʻOi aku ka ikaika o ka tensile ma mua o 1000 MPa

  • Kūleʻa maikaʻi loa no ka hana haʻahaʻa a kaumaha

  • ʻO ka paʻakikī kaulike e pale i ka haki ʻana ma lalo o ka haʻalulu a i ʻole ke kaumaha mau

At sakysteel, Hoʻolako pinepine mākou i ka 4140 kila i kakūlana kinai ʻiae hoʻonui i ka ikaika a me ka hana ʻaʻahu. He mea kūpono kēia no nā mea hoʻoikaika e like me nā shafts, axles, a me nā blanks gear.

Mechanisms Behind 4140's Wear Resistance

ʻO kekahi mau mea e hoʻopili ai i nā waiwai kūpaʻa o 4140 alloy steel:

  • Maʻiʻo Chromium
    Hoʻonui i ka paʻakikī a pale i ka ʻaʻahu abrasive.

  • Hoʻohui Molybdenum
    E hoʻomaikaʻi i ka ikaika a hoʻemi i ka pilikia o ka hoʻomaʻamaʻa wela i nā wela kiʻekiʻe.

  • ʻO ka Microstructure maikaʻi
    Hoʻokumu ʻia ka 4140 i hoʻomaʻamaʻa ʻia i ka wela i kahi ʻano martensite maʻemaʻe e kūʻē i ka deformation a me ka scuffing.

  • Ka Hoʻomalu Paʻa Paʻa
    Hiki ke paʻakikī ke kila i ke kumu a iʻole ke koho kohoʻia ma kaʻilikai, e hāʻawi ana i ka maʻalahi no nā noi kiko'ī.

Hoʻohālikelike i ka 4140 Wear Resistance i nā mea ʻē aʻe

4140 vs 1045 ʻO ka hao hao
ʻOi aku ka maikaʻi o ka pale ʻana o 4140 ma muli o ke kiʻekiʻe o ka paʻakikī a me ka ʻike paʻa. Ua kūpono ʻo 1045 no nā noi haʻahaʻa haʻahaʻa.

4140 kū'ē i nā kila mea hana (e laʻa, D2, O1)
ʻO nā kila kila e like me D2 ke hāʻawi aku i ke kūpaʻa ʻoi aku ka maikaʻi i nā kūlana koʻikoʻi, akā ʻoi aku ka palupalu a ʻoi aku ka paʻakikī i ka mīkini. Loaʻa ka 4140 i kahi kaulike maikaʻi no nā ʻāpana ikaika e koi ana i ka ikaika a me ka paʻakikī.

4140 kūʻē i nā kila ʻino (e laʻa, 316)
Kūʻē nā kila kila i ka ʻinoʻino akā ʻoi aku ka wikiwiki ma lalo o ka ukana. Koi ʻia ʻo 4140 no nā kaiapuni maloʻo a me ka mechanical kahi i ʻoi aku ka ʻino o ka friction ma mua o ka corrosion.

ʻO nā noi honua maoli e hilinaʻi nei i ka pale ʻana o 4140

Ma muli o kona ʻano paʻakikī a me ka paʻakikī, hoʻohana ʻia ʻo 4140 i kahi ākea o nā ʻāpana ʻaʻahu:

ʻOihana Kaʻa

  • Nā lāʻau hoʻoili

  • Nā kāmele

  • ʻO nā puʻupuʻu hoʻokele

  • ʻO nā mea hakahaka a me nā spacers

Mea Paahana a Make

  • Kuʻi

  • Mea paʻa

  • Nā poloka make

Ke kū nei kēia mau noi i ke koʻikoʻi, ka hakakā, a me ka hopena - ʻo ka hana ʻana i ka pale ʻana i ka lole he mea koʻikoʻi no ka hana palekana, kūpono, a lōʻihi.

Hiki iā 4140 ke mālama ʻia i ka ʻili no ka pale ʻana i ka lole ʻoi aku ka maikaʻi?

ʻAe. 4140 kila ua kūpono loa meʻenekinia ʻilinā ʻenehana e hoʻoikaika hou i ka pale ʻana i ke kapa:

  • Nitriding
    Hoʻopuka i kahi ʻāpana ʻili paʻakikī (a hiki i 65 HRC) me ka ʻole o ka hoʻololi ʻana i ka ʻāpana. Kūpono no ka mea hana.

  • Hoʻopaʻa paʻakikī
    Hoʻopaʻakikī paʻakikī i ka ʻili i ka wā e paʻa ana i kahi kumu paʻa-maʻamau i nā kumu a me nā mea hana.

  • ʻO ka hoʻopaʻa ʻana
    Hoʻohui i ke kalapona i ka ʻili no ka paʻakikī hou. He kūpono no nā ʻāpana i ʻike ʻia i ka friction a me ke kaomi.

At sakysteel, hāʻawi mākou i ke kākoʻo ʻenehana no nā mea kūʻai aku e ʻimi nei i nā mea nitrided a i ʻole induction-hardened 4140.

Nā Pōmaikaʻi Koʻikoʻi o 4140 no nā noi ʻaʻahu

  • ʻO ka paʻakikī o ka ʻili kiʻekiʻe (a hiki i 50 HRC a i ʻole)

  • ʻOi maikaʻi ʻo Core Toughnesse pale aku i ka pohā

  • Paʻa ma lalo o ka welaa me ka hoʻouka ʻana

  • Kūʻai-Ponohoʻohālikelike ʻia me nā kila mea hana

  • Maʻalahi e Mīkini a Weldma mua o ka lapaʻau hope ʻana

  • Kākoʻo i ka paʻakikī o ka ʻili

ʻO kēia mau mea maikaʻi e hoʻolilo iā 4140 i kahi koho no nā mea ʻenekinia e hoʻolālā ana i nā ʻāpana neʻe e pono e mau.

ʻO ka hōʻoia maikaʻi mai sakysteel

I ka wā e pili ana i ka pale ʻana i ka lole,ʻO ka mana maikaʻi nā mea a pau. Ma kasakysteel, hōʻoia mākou i ka hana kūlike me:

  • Hoʻopaʻa ʻiakemika a me ka mechanical analysis

  • Ka nānā ʻana i ka mālama ʻana i ka wela

  • ʻO ka hoʻāʻo paʻakikī pololei

  • EN10204 3.1 palapala hōʻoia

  • Kūkākūkā lāʻau lapaʻau koho

Hāʻawi mākou i ke kila 4140 i loko o ka ʻōwili wela, huki ʻia ke anu, hoʻopaʻa ʻia, a me nā ʻano hana pololei, i hoʻopili ʻia i nā koi o kāu noi.

Ka hopena

No laila pehea ka paʻakikī o ke kila 4140—maoli? Ua maopopo ka pane:paakiki loa, ʻoi aku ka maikaʻi ke mālama pono ʻia ka wela. Me kona kaulike maikaʻi loa o ka paʻakikī o ka ʻili, ka ikaika kumu, a me ka machinability, hāʻawi ʻo 4140 alloy steel i ke kūpaʻa ʻaʻahu pono i nā mea āpau mai nā axles kaʻa a hiki i nā mea hana drill hana kaumaha.

Inā pili kāu noi i ka hakakā, ka hopena, a i ʻole ka abrasion,4140 kila mai sakysteelhe hopena hilinaʻi i kūkulu ʻia no ka lōʻihi a me ka hana.
